Studies of Dimensional Stability, Thermal Stability and Biodegradation Resistance Capacity of Chemically Treated Bamboo
Runumee D. Borthakur and P.K. Gogoi

Abstract:
Bamboo is the world’s fast growing and widely used lignocellulosic versatile material. Like other biological materials, bamboo is susceptible to environmental degradation such as moisture, heat, rain, insects etc. as well as dimensional variation when exposed to natural environmental conditions although, with the use of appropriate treatments, the shelf-life of these materials can be prolonged. Chemical modification of split bamboo with a bulk Monomer like Methyl Methacrylate (MMA) or butyl methacrylate (BMA) in the presence of a dithioligand was studied. Polymerisation of MMA and BMA was possible by heat treatment as the catalyst. The dimensional stability efficiency of the treated sample in terms of Anti-shrink Efficiency (ASE%) was improved compared to untreated samples, as were the mechanical strength properties modulus of rupture and modulus of elasticity. The efficacy of the preservative chemicals for the treatment of bamboo samples was evaluated in ground contact against termite and fungus and found to be improved on treatment. The penetration of the preservative chemicals and deterioration of the bamboo samples after burial test was evident from Scanning Electron Micrograph (SEM). From the thermal analysis data of the treated and untreated samples, it was observed that the percentage of weight loss decreases in treated samples compared to untreated sample. The interaction of the bamboo component and chemicals was confirmed by FTIR spectroscopy.
