Abstract

The goal of this study was to investigate the effect of modified rice straw ORS on the mechanical and thermal properties of modified rice straw-polycaprolactone composites ORS-PCL-Cs. The composites Cs of polycaprolactone PCL with ORS were successfully synthesized using the solution-casting method. The RS modified with octadecylamine ODA as an organic modifier. The prepared composites were characterized by using powder X-ray diffraction XRD, thermogravimetric analysis TGA, scanning electron microscopy SEM, and Fourier transforms infrared spectroscopy FT-IR, and mechanical properties were investigated. Composites of ORS-PCL showed superior mechanical properties due to greater compatibility of ORS with PCL. The XRD results showed that the intensity of the peaks decreased with the increase of ORS content from 1.0 to 7.0 wt.% in comparison with PCL peaks. Tensile measurement showed an increase in tensile modulus but a decrease in tensile strength and elongation at break as the ORS contents are increased from 1.0 to 7.0 wt.%; on the other hand, tensile strength was improved with the addition of 5.0 wt.% of ORS. Thermal stability was decreased with the increase of ORS contents. SEM micrograph indicated good dispersion of ORS into the matrix, and FT-IR spectroscopy showed that the interaction between PCL and ORS is physical interaction.
