Research on Structure and Sorption Properties of Affiliative Polymer Piezoelectric Sensor Film Coating

摘要

Thin nanocomposite organic film coating with exactly thickness and high uniformity on the surface of the affiliative polymer piezoelectric sensor may be obtained using vacuum electron beam dispersion (EBD) coating technology. Structure and sorption properties of the thin film coating are studied. An experimental survey shows that EBD coating technology can produce a uniform thickness of the thin film coating when the cellulose treated as raw materials, and the physical and chemical analyses show that the coating has a high performance of absorption using the method of infrared spectroscopy. Meanwhile, the absorption and sensitivity performance of the thin film coating will change if other organic materials are added to the thin film coating. It is shown that cellulose based coatings have high sorption properties and may be used for gas sensing layers.
