Abstract

A series of waterborne poly(urethane-urea) anionomers were prepared from isophorone diisocyanate (IPDI), polycaprolactone diol (PCL), dimethylol propionic acid (DMPA), ethylene diamine (EDA), and triethylamine (TEA), NaOH, or Cu(COOCH3)2 as neutralizing agent. This study was performed to decide the effect of neutralizing agent type on the particle size, viscosity, hydrogen bonding index, adhesive strength, antistaticity, antibacterial and mechanical properties. The particle size of the dispersions decreased in the following order: TEA based samples (T-sample), NaOH based samples(N-sample), and Cu(COOCH3)2 based sample (C-sample). The viscosity of the dispersions increased in the order of C-sample, N-sample, and T-sample. Metal salt based film samples (N and C-sample) had much higher antistaticity than TEA based sample. By infrared spectroscopy, it was found that the hydrogen bonding index (or fraction) of samples decreased in the order of T-sample, N-sample, and C-sample. The adhesive strength and tensile modulus/strength decreased in the order of T-sample, N-sample, and C-sample. The C-sample had strong antibacterial halo, however, T- and N-samples did not.
