Abstract

The use of natural fibers as reinforcing fillers involves performing surface treatments to reduce hydrophilicity and improve the compatibility of the vegetable particle with polymers. In this investigation natural Smooth Retama fiber (Telinne Monspessulana) was treated with silane coupling agent vinyl-trimethoxysilane (VTMS). Silane was pre-hydrolyzed in aqueous ethanol /water 80/20 for 1 h, maintaining the pH between 3.0-3.5. Subsequently, the fiber was immersed in the solution of pre-hydrolyzed silane for 3 h. Treated fiber was washed with distilled water and dried for 24 h at 45 °C. Finally, soxhlet extraction was performed to the fiber to remove residual silane. The influence of dicumyl peroxide (DCP) catalyst on the silane grafting process with the natural fiber was analyzed. By analyzing infrared spectroscopy FTIR, ash content, and scanning electron microscopy (SEM) quantitatively and qualitatively the positive effect of organic peroxide was determined as a catalyst for VTMS.
