The aim of this investigation was to study the effect of surface thermal oxidation of bamboo/poly(methyl methacrylate) composite by irradiation. Thermal oxidative effects on the surface energy of bamboo fiber were measured by radiation as a function of exposure time and temperature. Oxidized bamboo/poly(methyl methacrylate), after exposure to air at temperatures of 100°C and 110°C, had a range of maximum surface energies from 38 to 41 mJ/m2. Comparisons between Fourier transform infrared carbonyl peak growth and the surface energy showed that both methods detect oxidation, though the increase in surface energy was detected before the carbonyl peak growth was noticeable. The work of adhesion predicted by the surface free energies obtained in this work between a coated calcium carbonate and bamboo fiber changes by 10% due to the oxidation of the polymer at 110°C. The structural results were discussed in the oxidation chemistry of the macromolecule.
