Laser Surface Modification And Adhesion

The book provides a unique overview on laser techniques and applications for the purpose of improving adhesion by altering surface chemistry and topography/morphology of the substrate. It details laser surface modification techniques for a wide range of industrially relevant materials (plastics, metals, ceramics, composites) with the aim to improve and enhance their adhesion to other materials. The joining of different materials is of critical importance in the fabrication of many and varied products.

The acronym Laser is derived from Light Amplification by Stimulated Emission of Radiation. With the advent of the ruby laser in 1960, there has been tremendous research activity in developing novel, more versatile and more efficient laser sources or devices, as lasers applications are ubiquitous. Today, lasers are used in many areas of human endeavor and are routinely employed in a host of diverse fields: various branches of engineering, microelectronics, biomedical, medicine, dentistry, surgery, surface modification, to name just a few. In this book (containing 10 chapters) we have focused on application of lasers in adhesion and related areas. The topics covered include: • Topographical modification of polymers and metals by laser ablation to create superhydrophobic surfaces. • Non-ablative laser surface modification. • Laser surface modification to enhance adhesion. • Laser surface engineering of materials to modulate their wetting behavior • Laser surface modification in dentistry. • Laser polymer welding. • Laser based adhesion testing technique to measure thin film-substrate interface toughness. • Laser surface removal of hard thin ceramic coatings. • Laser removal of particles from surfaces. • Laser induced thin film debonding for micro-device fabrication applications.

This book documents the proceedings of the Fourth International Symposium on Polymer Surface Modification: Relevance to Adhesion held under the auspices of MST Conferences, LLC in Orlando, FL, June 9-11, 2003. Polymers are used for a variety of purposes in a host of technological applications and even a cursory look at the literature will evince that currently there is tremendous interest and R&D activity in the area of polymer surface modification to attain their desired surface characteristics, particularly to enhance their adhesion. This volume contains a total of 25 papers which were properly peer reviewed, revised and edited. So this book is not merely a collection of papers, rather represents the highest standard of publication. The book is divided into three parts: 1. Plasma Surface Modification Techniques; 2. Other / Miscellaneous Surface Modification Techniques; and 3. General Papers. The topics covered include: low pressure plasma surface modification of a variety of polymers using various gases; atmospheric pressure plasma treatment; improvement of stain release properties of fabrics; modification of electrostatic properties of polymers; photon-based processes for surface modification of fibers; excimer UV light treatment; excimer laser surface treatment; low-energy ion treatment; photo-grafting and photo-curing; metallization of treated polymers; chemical (wet) functionalization of polymers; adhesion of paints to thermoplastic substrates; polymer release surfaces; nanolithography in polymer films; gas barrier properties of ceramic layers on polymers; and modification of interphase layer and relevance to adhesion. This volume and its predecessors containing plentiful information should serve as a comprehensive source of latest R&D activity in the highly technologically important arena of polymer surface modification. Anyone interested –centrally or peripherally– in knowing or learning about the various ways to modify polymer surfaces should find this book of immense value.

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.

The topic of polymer surface modification is of tremendous contemporary interest because of its critical importance in many and varied technological applications where polymers are used. Currently there is brisk research activity in unraveling the mechanisms of surface modification and finding ways to prolong the life of surface treatment. Also there is acute interest and need to devise new, improved and economical means to modify polymer surfaces. This book is divided into three parts as follows: Part 1: Surface Modification Techniques; Part 2: Interfacial Aspects and Adhesion; Part 3: General Papers. The topics covered include: various techniques for surface modification including plasma (both vacuum and atmospheric pressure), ozone, photografting, UV photo-oxidation, laser, use of charged particles and others for a variety of polymers; longevity of surface treatment; hydrophobic recovery; fabrication of high-density polymer nano-dots; immobilization of organometallic catalysts on textile carrier materials; polymer membrane antifouling properties; electroless metallization of polymers; effects of surface modification on interfacial shear strength of composites, cord/rubber adhesion, adhesion of UV-curable coatings and attachment of hyperbranched polymers; plasma polymerization; block copolymers; application of plasma technology in decontamination of heat-sensitive polymer surfaces. In essence this book reflects the current state-of-the-knowledge in the arena and represents the work of many renowned scientists and technologists. It should be of interest to anyone with a desire or need to learn the latest R&D activity in this domain and the information contained here should be very valuable in deciding the optimum surface modification technique for his/her particular requirements.
