Palm Kernel Oil‑Based Polyester Polyurethane Composites Incorporated With Multi‑Walled Carbon Nanotubes For Biomedical Application

Abstract

In this study, polyurethane (PU) films from palm kernel oil-based polyester (PKO-p) incorporated multi-walled carbon nanotubes (MWNTs) were prepared via evaporative casting method. Nanoparticle fluid dispersions containing 0.01, 0.04 and 0.08 % wt. of MWNTs were added into PKO-p-based resin and mixed by digital probe sonicator for 20 min followed by mixing with isocyanate to produce PU-MWNTs composite films. The mechanical properties, water resistance, water vapor transmission rates (WVTR), biocompatibility, and antibacterial activities of the PU-MWNTs composite films were examined.
