摘要

This study reports the use of nanocomposite of nylon 6 and modified carbon nanofibers (CNF) for production of new non-woven fabric by melt blowing, which is a simple, solvent-free and easily scalable method. In this research, concentrations of 0, 0.25, 0.5, and 1 wt % of CNF were used. The obtained nonwoven fabrics were evaluated to identify their physical and chemical changes using: X-ray diffraction (XRD), thermogravimetric analysis (TGA), SEM-EDS, contact angle, mechanical properties, thermicity index and electrical resistivity. The thermal stability of the obtained materials increased with higher modified CNF content, this behavior was observed in the TGA analysis. Visually, by SEM, it was observed that with higher CNF content, the fiber diameter increased from 11.31 μm for nylon 6 to 21.75 ± 9.7 μm for the sample with the highest modified nanoparticle content (Nylon 1% CNF). The contact angle evaluation showed the same trend, with higher particle content, the value increased, from 127° for nylon 6 to 132° for the sample Nylon 1% CNF. Mechanical tests show that compared to pure nylon 6, maximum breaking strength and elongation break increase as the percentage load increases. From thermicity index results, nylon 6 non-woven fabrics have very good heat retention, only 21.21% of the infrared radiation could be reflected in the atmosphere. For Nylon CNF 0.5% and Nylon CNF 1%, the thermicity was better, because the infrared radiation only leaked at approximately 8%. Black plastic mulch is widely used to warm the soil and prevent heat loss from the soil at night. Furthermore, the electrical resistivity improved by adding modified CNF.
