A novel antistatic polyurethane hybrid based on nanoscale ionic material

Abstract

A novel liquid-like nanoscale ionic material (NSiF-Hs) at ambient temperature was synthetized. NSiF-Hs, as supramolecular cross-linking agents, can react with prepolymer (polytetramethylene ether glycol and 4,4′-diphenyl methane diisocyanate) to prepare a novel polyurethane hybrid (PU/NSiF-Hs). The tensile strength and the elongation at break of PU/NSiF-Hs hybrids both increased with augmented proportion of NSiF-Hs when it was less than 4 wt%. Especially, NSiF-Hs endowed PU hybrid with permanent antistatic property duo to ionic bond and hygroscopicity of residual hydroxyl groups on NSiF-Hs. The surface resistivity of PU hybrid with 8 wt% NSiF-Hs reached 7.35 × 107 Ω/sq.
