Conteúdo: | Chopped sisal fibers and finely powdered high-density polyethylene were surface functionalized using dichlorosilane (DS) under radio frequency (RF)-plasma conditions and characterized by electron spectroscopy for chemical analysis (ESCA) and fluorescence labeling techniques. A high-capacity (10 L.), rotating, 13.56 MHz, electrodeless plasma installation, specially designed to allow the unform surface modification of powdery and particulate matter of irregular shape, was used. A three-factor fractional experimental design was employed to evaluate the effect of RF-power, pressure, and reaction time on the ESCA-based relative atomic composition of plasma-treated samples. It was demonstrated that -SiHxC1y functionalities are present on plasma-exposed surfaces and these functionalization reactions ca be controlled by selecting proper plasma parameters.
