Paper Title:
Vapor-Induced Response of HTPB/MWNTs-COOH PU Conductive Films Based on Hydrogen Bonding Interactions
  Abstract

Novel polyurethane (PU) conducting films consisting of hydroxyl-terminated polybutadienes (HTPB) and carboxyl functionalized multi-walled carbon nanotubes (MWNTs-COOH) were developed by a simple coupling approach based on hydrogen bonding interactions between MWNTs-COOH and PU moieties. The morphologies and structural characterization were conducted by means of FTIR, TEM and TGA etc; and the influence of the MWNTs-COOH loading and curing temperature on vapor response was investigated. The experimental results indicated that a micro-phase separation structure between soft and hard segments was formed, and MWNTs-COOH was tightly encapsulated by PU moieties and homogeneously dispersed in the PUs. The developed films displayed selective response to non-polar organic solvent vapor and good long-term stability.
