New study aims at the development of novel waterproof and breathable membranes
Increased water resistance When the HTPDMS content of WPUA was 10.0 wt%, the water contact angle of the cured film was the largest at 114°, which indicated that the surface of the cured film has been changed from a hydrophilic surface to a hydrophobic one. Thermogravimetric analysis results showed that the initial decomposition temperature of WPUA film gradually increased with adding of HTPDMS, performing better thermal stability.
Test results indicated that with increasing HTPDMS content in the WPUA, the particle size of the emulsion was increased significantly, while the absolute value of Zeta potential was increased slightly. The resistance of WPUA cured film to water was increased. The ultimate water absorption declined from 11.12 % to 6.81 % and the equilibrium time of water absorption extended from 50 h to more than 100 h.
