A study on the functional and tensile properties of polyurethane composite film with carbon nanotube fibers

摘要

The purpose of this study is to propose a process of fabricating conductive polyurethane (PU)/CNT composite films that possess electrostatic discharge (ESD), UV cut, and warming characteristics. Polyvinylpyrrolidone (PVP), Methyl Ethyl Ketone (MEK), Iso-propanol (IPA) were used as the dispersion agent to facilitate the dispersion of CNT fiber before blending with PU in a planetary stirring defoaming machine for thorough uniform mixing. In this study, various amounts of CNT fibers were added into the solvent-based PU solution to improve the electrical conductivity of the conventional PU product. Based on the test results, the PU with CNT fiber shows better performance than that of conventional PU. This paper successfully prepared the PU/CNT composite film which coat on the fabric to prevent static electricity generation, rapid warming, improve home security and the versatility of outdoor and camouflage military products applications.
