Notes:
Interfaces of evaporated viterous selenium and various organic polymeric resins of both the thermosetting and thermoplastic type have been studied by ultra-thin sectioning and transmission electron microscopy techniques. Epoxy, phenoxy, polyamide, butadien-styrene copolymer, vinyl-toluene-butadiene copolymer, resins as well as polyethylene are among those organic polymers studied. Interfaces prepared by vaccum evaporation of selenium onto the various substrates and under varying processing conditions were examined. Intermixing and interdiffusion of the inorganic and organic polymers in the interfacial region were observed in certain cases when selenium was evaporated onto incompletely curved epoxy or lower viscosity polymers. These occurrences were found to contribute significantly to the mechanical strength of the assembly. Electrical properties of certain specific systems have also been investigated.
