UV Curing Kinetics and Properties of Polyurethane Acrylate/Multi-walled Carbon Nanotube Coatings

Abstract

Polyurethane (PU) acrylate/multi-walled carbon nanotube (MWNT) composite coatings were synthesized by simple UV irradiation at ambient temperature. In particular, aromatic PU acrylate and aliphatic PU acrylate were chosen to examine the effect of the pi-pi interaction between the MWNTs and the aromatic PU acrylate. The electrical properties showed that the incorporation of only a few hundred MWNT in wt% was sufficient for electrostatic dissipative applications. Other properties, such as the rheological properties and transparency were also examined.
