Paper Title:
Effects of Modified Carbon Nanotubes on Curing and Mechanical Properties of N-Phenyl Maleimide/Bismaleimide Composites
  Abstract

One kind of bismaleimide resin (BMI) was prepared from Michael addition reaction with modification carbon nanotubes (m-CNTs). CNTs were modified by N-phenyl maleimide (N-PMI) and ethylenediamine. The effect of modification was determined by NMR spectra and Raman Analyser. The cure kinetics, thermal behavior and mechanical property of carbon nanotubes/bismaleimide-o,o-diallyl bisphenol A resin (CNTs/BMI-BA) were studied. It was found that this kind of CNTs can be easily dispersed in high performance resin only with a slight stirring. The curing apparent activation energy (Ea) decreased with the increasing amount of m-CNTs. The maleimide-CNTs could fully express its unique mechanical properties and dramatically increase the reaction activity, the storage modulus, impact strengths and bending stress of the CNTs/BMI-BA composites while the CNTs-COOH reduce the important mechanical properties. These critical enhancements will definitely help to attract more researches in this field.
