Quantifying The Use Of Chloroform Vapor Exposure To Improve The Adhesion Of Au Thin Films Onto Pmma, Kathleen T. Krist

Senior Honors Projects, 2010-2019

The metallization of Au onto plastics is an important processing step in applications such as the aerospace and automotive industries, the field of microelectronics, and the fabrication of microfluidic devices. While its corrosion resistance and excellent electrical and thermal conductivity make Au a useful choice, its inertness results in poor adhesion to polymer surfaces. Previous studies have indicated that exposing commercially available poly(methyl methacrylate) (PMMA) sheets to chloroform vapor following Au deposition significantly improves adhesion. In this study, we utilized electron-beam evaporation and magnetron sputtering to deposit Au thin films onto 1.50 mm thick PMMA and exposed the samples to …
