Contact Angle Of Different Portion Of Beting Bamboo (Gigantochloa Levis) Treated With Maleic Anhydride For Composite Materials

Beting bamboo or scientifically known as Gigantochloa Levis is readily available, can be obtained at lower cost, easy to harvest, and good in mechanical properties. Alteration of bamboo surface using chemical treatment prior to making it as a product has been reported to have potential to enhance the structural and functional properties of the product. The objective of this study is to determine which portion of bamboo (outer and inner) is good in adhesion as well as the effect of different percentage of treatment (Maleic Anhydride (MA) - 0%, 0.5%, 1% and 2%) on bamboo surface properties such as contact angle, and chemical structure. The contact angle, and chemical component of bamboo samples were determined using contact angle meter, and FT-IR respectively. It is concluded that the combination ofinner portion of bamboo with 1% MA treatment showed the mostsuitable outcome to be used in enhancing the surface properties of a product. Based on the spectroscopic analysis using FTIR method, it was concluded that treating bamboo with MA chemically modified the surface of bamboo as indicated by the spectrum on the analysis.There were major differences at the spectrums that showed different assignments.
