Available in PDF, EPUB and Kindle. Book excerpt: Hard transparent coatings are an essential component of structures involving polymer surfaces. An important application is airplane passenger windows, which are subject to large variations in pressure, temperature and humidity as well as UV exposure and abrasive conditions. The coatings suitable for such extreme environments must have high hardness, resistance to UV degradation and excellent adhesion to the polymer substrate. Measuring the adhesion of a hard coating on a compliant substrate is not trivial; hence, qualitative cross-cut tape tests have been the standard for automotive and aerospace industries. In this dissertation we address the quantitative assessment of adhesion of hard transparent coatings on polymer substrates. An asymmetric double cantilever beam specimen was employed to sample the interface without contribution from crazing in the substrate. Fracture energies of coatings that had passed standard tests were found to vary from 1.4 J/m2 to 22 J/m2. Significant subcritical crack growth was observed in coatings on windows with interfacial fracture energy of 7 J/m2. Cracks were found to continue to grow at driving forces below 2 J/m2 due to viscoelastic deformation at the crack tip. Simulated outdoor weathering decreased the adhesion energy and led to cracking and delamination. Driving force for cracking and delamination was correlated to UV cross-linking of the coating; FTIR evidence showed that the ratio of network forming Si--O--Si bonds increased with outdoor exposure. The effect of surface pre-treatments on adhesion was assessed. Mechanical polishing and UV-Ozone treatment were found to increase adhesion significantly. The effect of UV absorbers on stress generation in coatings exposed to UV was investigated. A cyanoacrylate absorber was found to perform better than a benzophenone absorber at high concentrations. However, both absorbers seemed to change the molecular structure of the coating and did not increase the lifetime of the coating significantly. Atmospheric plasma deposition was employed as a solvent-free and wasteless alternative to sol-gel processing of hybrid coatings. We focused on molecularly bridged hybrid coatings for improved cohesion and resistance to water assisted crack growth. A high temperature precursor delivery system was designed and constructed for deposition of molecularly bridged hybrid silica coatings. Bridged precursors with very low vapor pressure were deposited on silicon and polycarbonate substrates. The effects of precursor flow rate, temperature and other plasma parameters on deposition rate were investigated. Bridged precursor coatings developed significantly higher growth stresses than curing stresses in sol-gel coatings, but the former were comparable to atmospheric plasma coatings deposited using conventional silanes.

This book was released on 2014 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of transparent, hard, scratch-resistant coatings has enabled the transition from glass to transparent plastics in the ophthalmic, automotive and aviation industries. Drivers for this switch include weight reduction, design flexibility and safety. Currently, the state of the art technology uses liquid applied resin coatings in the form of SiO2 nanoparticles in an organic matrix. This mature technology has been developed over the past 40 years. As an alternative, this study has investigated the development of vacuum based hardcoatings deposited via microwave PECVD. These coatings are derived from tetramethyldisiloxane and oxygen. The resulting coatings can be described as organosilicone polymers. The main advantage of vacuum based deposition is the ability to grade the coating's chemical and mechanical properties across its thickness by ramping up the oxygen flow over the course of deposition. Thus, the coating can be mechanically matched to the substrate and then transformed to be harder and stiffer at its surface, so that it can provide a durable and scratch resistant coating.

Book excerpt: This conference provided a forum where researchers and industrialists working with glass and thin films, could meet and discuss common, complex problems. Many apparently old fundamental procedures and processes are still under investigation, due to their complexity. In particular it is often so that experience dictates the operating conditions, e.g. a special glass treatment or a special coating process rather than the understanding of the treatment or the process itself. It was therefore the aim of this conference to discuss the various problems and to deepen the knowledge that is useful for industrial situations. Based on the fundamental steps of glass fabrication, modification and film deposition, and property studies and the search for possible applications, a wide range of glass and plastic treatments have been carefully considered in this book by experts working in the field.
