Abstract

A series of aqueous polyurethane-urea (PUU) dispersions having urushiol were synthesized by in situ step polymerization of isophorone diisocyanate (IPDI), poly(ethylene glycol) (PEG, M_n = 1000 g/mol), urushiol, dimethylol propionic acid (DMPA), and ethylene diamine (EDA). Urushiol was extracted with acetone from the purified lacquer of Toxicodendron vernicifluum and the different concentrations (0, 11.8, 17.6, and 22.2 wt.% based on the total solids) of urushiol were introduced during the PU prepolymer synthesis. Thermal stability, mechanical strength, antimicrobial, and anticorrosive properties of the urushiol/PUU films were investigated in terms of urushiol concentration.
