It was found that increasing the CSP content decreased the tensile strengths and elongations at break of the PLA/CSP biocomposites. However, incorporating CSP increased their modulus of elasticity. The tensile strengths and modulus of elasticity of the PLA/CSP biocomposites were enhanced by the presence of 3-APE, which can be attributed to a stronger filler-matrix interaction. The thermal stabilities of the biocomposites increased with the filler content, and they were enhanced by 3-APE treatment. Meanwhile, the presence of CSP increased the glass transition temperatures (T g) and crystallinities (X c) of the PLA/CSP biocomposites at a filler content of 30 php. After 3-APE treatment, T g and X c of the PLA/CSP biocomposites increased due to enhanced interfacial bonding. The presence of a peak crystallization temperature (T c) for the PLA/CSP biocomposites indicated that the CSP has a nucleating effect. The melting temperatures (T m) and the T c values of the biocomposites were not significantly affected by the fillercontent and 3-APE. PLA/CSP biocomposites that had been treated with 3-APE presented the strongest filler-matrix interaction, as confirmed by SEM. 2014-05-30T02:11:08Z 2014-05-30T02:11:08Z 2012 Article Journal of Polymer Research vol.19(5), 2012, pages 1-8 10229760 http://link.springer.com/article/10.1007%2Fs10965-012-9859-8 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34892 10.1007/s10965-012-9859-8 en Springer Netherlands
