Thermal Characterization of Low Grade Wood Polyacylonitrile Composite
A series of wood polyacrylonitrile (PAN) composites (WPCs) were synthesized through impregnation polymerization of Eucalyptus wood (Eucalyptus Grandies) by acrylonitrile (AN) in methanol (20-60% v/v) in the presence of benzoyl peroxide (1.0% w/v) in benzene medium at 70 ±10C. This resulted in corresponding WPCs with polyacrylonitrile (PAN) loading in the range of 15.5-20%. Loading of PAN into wood, as ascertained through TGA, DTGA and DTA and supported by Fourier Transform Infrared Spectroscopy (FTIR) as well as Scanning Electron Microscopy (SEM) was found to increase the resistance against thermo-oxidation of WPCs in comparison to untreated wood.
