Abstract

A Fourier transform infrared (FTIR) spectroscopy analysis of the surface chemistry of marine grade plywood is presented. One side of the plywood was irradiated with plasma enhanced chemical vapor of 85% phosphoric acid for 30 mins with different plasma current discharges at 1Torr and 0.9 Torr. The H₃PO₄ plasma treatment of the wood samples brought about decrease in the O-H, C-H, C=O and C-O absorption bands which suggests molecular substitution of phosphorous functional groups of P-O and P=O. These effects where observed significantly at 15 and 20 mA discharge current at 1 Torr. However further surface characterizations of samples are needed to identify compounds formed on the surface.
