Abstract

This research was carried out to investigate the effectiveness of polydimethylsiloxane (PDMS) and hexamethyldisiloxane (HMDSO) as compatibilizing agent in producing wood composites of betel nut fiber/polypropylene (BNF/PP) and betel nut fiber/polystyrene (BNF/PS). Wood composite was prepared by blending 40% of matrix polymer and 60% of treated and untreated BNF using internal mixer Brabender Plasticoder at 170˚C with 50 rpm rotor speed for 13 minutes. The treatment was done prior to blending the materials by immersing the BNF in PDMS and HMDSO solutions with 1%, 3% and 5% of concentrations for 24 hours. The effects of 1% HMDSO treatment on BNF/PP composite contributed to high flexure strength and impact strength which are 19.2 MPa and 7.9 kJ/M2 respectively while the percentage of water absorption showed the minimum value of 6.7%. The impact strength of BNF/PS composite treated with 3% HMDSO showed maximum value that is 4.7 kJ/M2 and minimum percentage of water absorption, 6.8%. However, the flexure strength of untreated BNF/PS composite is higher than treated BNF/PS composite with value of 4.7 MPa. The morphology of treated BNF/PP composites from SEM micrographs showed better interface interaction between fibers and matrices. FTIR spectra showed the presence of siloxane groups such as Si-O, Si-CH3, Si-(CH3) and Si(CH3) as a result of HMDSO and PDMS treatment. Based on the characterization analysis, HMDSO treated composite of BNF/PP showed more effective interfacial interaction between BNF and matrices.
