Thermal degradation of environmentally friendly phenolic resin/Al₂O₃ hybrid composite

Abstract

Abstract An environmentally friendly phenolic resin/Al 2 O 3 hybrid composite was prepared. Al 2 O 3 particles were pretreated with a silcane coupling agent, then the mixture of paraformaldehyde and treated Al 2 O 3 was grinded with ball crusher for several hours, and added during the phenolic resin polymerization process, finally got the hybrid composite. The kinetic parameters of thermal degradation were calculated by the methods of Kissinger, Flynn‐Wall‐Ozawa and Crane. The thermal degradation activation energy of environmentally friendly phenolic resin/Al 2 O 3 hybrid composite is approximate three times of pure phenolic resin. The results show that the heat resistance is obviously improved. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
