Atmospheric Pressure Plasma For Surface Modification

This Book's focus and intent is to impart an understanding of the practical application of atmospheric plasma for the advancement of a wide range of current and emerging technologies. The primary key feature of this book is the introduction of over thirteen years of practical experimental evidence of successful surface modifications by atmospheric plasma methods. It offers a handbook-based approach for leveraging and optimizing atmospheric plasma technologies which are currently in commercial use. It also offers a complete treatment of both basic plasma physics and industrial plasma processing with the intention of becoming a primary reference for students and professionals. The reader will learn the mechanisms which control and operate atmospheric plasma technologies and how these technologies can be leveraged to develop in-line continuous processing of a wide variety of substrates. Readers will gain an understanding of specific surface modification effects by atmospheric plasmas, and how to best characterize those modifications to optimize surface cleaning and functionalization for adhesion promotion. The book also features a series of chapters written to address practical surface modification effects of atmospheric plasmas within specific application markets, and a commercially-focused assessment of those effects.

An indispensable volume detailing the current and potential applications of atmospheric pressure plasma treatment by experts practicing in fields around the world Polymers are used in a wide variety of industries to fabricate legions of products because of their many desirable traits. However, polymers in general (and polyolefins, in particular) are innately not very adhesionable because of the absence of polar or reactive groups on their surfaces and concomitant low surface energy. Surface treatment of polymers, however, is essential to impart reactive chemical groups on their surfaces to enhance their adhesion characteristic. Proper surface treatment can endow polymers with improved adhesion without affecting the bulk properties. A plethora of techniques (ranging from wet to dry, simple to sophisticated, vacuum to non-vacuum) for polymer surface modification have been documented in the literature but the Atmospheric Pressure Plasma (APP) treatment has attracted much attention because it offers many advantages vis-a-vis other techniques, namely uniform treatment, continuous operation, no need for vacuum, simplicity, low cost, no environmental or disposal concern, and applicability to large area samples. Although the emphasis in this book is on the utility of APP treatment for enhancement of polymer adhesion, APP is also applicable and effective to modulate many other surface properties of polymers: superhydrophilicity, superhydrophobicity, anti-fouling, anti-fogging, anti-icing, cell adhesion, biocompatibility, tribological behavior, etc. The key features of Atmospheric Pressure Plasma Treatment of Polymers: Address design and functions of various types of reactors Bring out current and potential applications of APP treatment Represent the cumulative wisdom of many key academic and industry researchers actively engaged in this key and enabling technology

This book addresses plasma modification of polyolefin surfaces. It comprises 21 chapters divided into three major sections. The first section covers the different techniques used for plasma modification of polyolefin surfaces and the effects of various gases as a surrounding medium, while the second provides a detailed analysis of the physics and chemistry of plasma modification and discusses various innovative characterization techniques, as well as ageing of the modified surface. It focuses on the analysis of changes in polymers’ surface chemistry using various spectroscopic techniques, and of changes in their surface morphology after plasma treatment using optical microscopy, electron microscopy and atomic force microscopy. In addition, it provides detailed information on the characterization of modified polymer surfaces. The book’s third and last section covers a range of applications of plasma-modified polyolefin surfaces varying from the packaging industry to the biomedical field, and shares valuable insights on the lifecycle analysis of plasma modification and modified surfaces.

Plasma is one of the most fundamental states of matter other than solid, liquid and gaseous. It consists of positive ions, neutral atoms, electrons, negative ions and neutral or charged molecules can be identified. Generally, plasma can be classified according to its gas temperature. Atmospheric-pressure plasma (APP), is actually a partly ionized gas. Non-equilibrium APP has an ability to produce a mixture of reactive species including, reactive oxygen species (ROS) and reactive nitrogen species (RNS), which can act as biologically active agents. This book discusses the processes, technology and applications of APPs. The first chapter examines the influence of APPs on biomolecules. Chapter Two focuses on the development and application of optical techniques for diagnosing gliding arc discharge at atmospheric pressure, emphasis being placed on gaining a better understanding of the spatial, temporal and spectral discharge characteristics. Chapter Three presents several approaches for such free-form plasma activation of different plastics and polymers based on direct and indirect dielectric barrier discharge (DBD) plasmas. Chapter Four reviews the combination of plasmachemical oxidation PCO and atmospheric pressure chemical vapour deposition APCVD for creating novel functional surfaces. Chapter Five reviews the impact of gas diffusion barrier film synthesis on polymers by atmospheric pressure plasma enhanced chemical vapour deposition. Chapter Six presents and discusses some of the most recent applications of microwave plasmas, with the view of understanding microwave plasma behaviour. Chapter Seven discusses selective synthesis of self-standing carbon nanostructures using microwave driven plasmas at atmospheric pressure conditions. Chapter Eight studies the application of non-thermal atmospheric pressure plasma in textiles. Chapter Nine reviews a current state of the art and opportunities for the use of plasma surface treatment in the coating and conversion of paper products.

This book chronicles the proceedings of the Second International Symposium on Polymer Surface Modification: Relevance to Adhesion held Newark, New Jersey, May 24--26, 1999. Polymeric materials are intrinsically not very adhesionable and this necessitates their surface treatment to enhance their adhesion characteristics to other materials. Since the first symposium on this topic, held in 1993, there has been a tremendous R&D activity in devising novel or ameliorating the existing techniques for surface modification of polymers. This volume contains a total of 32 papers, which have been rigorously peer-reviewed and suitably revised before inclusion in this volume. The book is divided into three parts as follows. Part 1: Plasma Surface Modification Techniques; Part 2: Other/Miscellaneous Surface Modification Techniques; and Part 3: General Papers. The topics covered include: plasma surface modification of a variety of polymers using various plasma gases; atmospheric plasma system; surface functionalization; ultrahydrophobic polymeric surfaces; metallization of plasma treated polymers; surface modification of polymers via molecular design for adhesion promotion; wet chemical methods for polymer surface modification; laser surface modification of various polymers; UV/ozone treatment; surface and interface studies of treated polymer surfaces by an array of techniques; bioadhesion of polymeric biomaterials to tissue; polymer-fiber systems; and plasma deposited coatings.
