Abstract:

To improve the temperature-sensitivity and moisture permeability of intelligent waterproof and moisture permeable membrane, poly-N-isopropylacrylamide (PNIPAM) was coated on hierarchical pore polyurethane (PU) membranes and PNIPAM/PU gradient composite membranes were prepared by adjusting the mass fraction of PNIPAM. Structure, thermo-sensitive hydrophilic-hydrophobic and thermo-sensitive moisture permeability were investigated. The results show that the construction of PNIPAM does not change the hierarchical pore structure. It has thermo-sensitive hydrophilic-hydrophobic transition properties, exhibiting hydrophilicity when temperature below the transition temperature (30 ℃), and hydrophobicity when temperature above this temperature. Meanwhile, the introduction of PNIPAM improves thermo-sensitive moisture permeability, from 4 843.4 g/(m2·24 h) of PU to 6 398.3 g/(m2·24 h) of PNIPAM/PU gradient composite membrane at 50 ℃ when mass fraction of PNIPAM is 6%. It was also found that the higher the content of PNIPAM, the more significant decrease in swelling property with the temperature increase.

Key words: hierarchical pore, gradient membrane, thermo-sensitive, hydrophilic-hydrophobic transition, moisture permeability, functional textile material
