Thermal Characterization of Neem and Cork Wood Polyacrylonitrile Composites
Wood polyacrylonitrile composite (WPC) from neem and cork woods were synthesized. The process was carried out through benzoyl peroxide(0.05mol/l) catalyzed impregnation polymerization of acrylonitrile 2mol/l, 4mol/l, 6mol/l into neem and cork woods in benzene medium at 75+-10c.The properties of WPC over untreated wood was evaluated. Loading of PAN into cork woods as ascertained through TGA, DTGA and DTA as well as Scanning Electron Microscopy (SEM) was found to increase the resistance against thermo-oxidation of WPCs in comparison to untreated wood. Themogravimteric analysis (TGA) is one of the techniques used to determine the thermal properties of wood.Wood polyacrylonitrile composite (WPC) from, mango and cork wood was synthesized. The process was carried out through benzoyl peroxide (0.05moll) catalyzed impregnation polymerization of acrylonitrile, 4mol/l, 6moll into cork wood and mango wood in benzene medium at 75+-10c. The properties of WPCs over untreated woods were evaluated in terms of Thermo gravimetric analysis (TGA) in Nitrogen. Thermo gravimetric analysis were improved with impregnation of polyacrylonitrile. Impregnation of polyacrylonitrile (PAN) into, mango, cork woods were confirmed through scanning electron microscope. In the present research effects have been made to develop such polyacrylonitrile impregnated composites in Benzene medium having improved thermal stability for there commercial exploitation for desirable purposes.
