Study of the dielectric constant of polyurethane/polybutyl-methacrylate interpenetrating polymer networks using metal-insulator-semiconductor structure
Abstract:Polyurethane/polybutyl-methacrylate interpenetrating polymer networks (IPNs) film was formed on n-Si substrate by the dropping technique. When aluminum (Al) was vacuum deposited on the top of the film, the Al/IPNs/n-Si (metal-insulatorsemiconductor) structure was fabricated successfully. With the aid of the high-frequency capacitance-voltage (C-V) characteristics at room temperature, the dielectric constant of IPNs was obtained. In the C-V curves, an increased hysteresis at high sweep voltage and a plateau in … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
