A highly crosslinked organic polymer that does not rely on an Interpenetrating polymer network (IPN) structure was investigated. a sacrificial layer of poly(4-hydroxystyrene) (PHS) was spin-coated to a thickness of 0.1 μm on a flat substrate. The crosslinking was monitored by using attenuated total reflectance Fourier transform IR spectroscopy. The 20 nm thick nanomembrane was transferred to a wire frame 1 cm in diameter. The epoxy nanomembranes were transferred onto anodized aluminum oxide (AAO) membranes for scanning electron microscopy (SEM) measurements. The electrical properties of the nanomembranes were studied on a p-type silicon wafer by using a potentiostat/galvanostat system. It was observed that the epoxy resin is highly compatible with many chemical substances and the behavior can be used to develop superior or functional and structural composites.
