Improvement of Surface Properties in Natural Fibers

This project focuses on enhancing the sustainability and added value of natural fibers, specifically Cardulovica Palmata, a renewable resource that requires less energy and generates less CO2 than synthetic fibers. The problem addressed is the need to improve the physical properties of these fibers to make them more competitive internationally and extend their useful life. The proposed solution involves chemically modifying the fiber surface to make it hydrophobic and impermeable, minimally altering its initial properties. This is achieved by applying low-pressure cold plasma for polymer deposition. The methodology relies on the exhaustive characterization of the fibers (natural and sulfur-treated) before and after plasma treatment. Thermal Analysis techniques such as Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) are employed, along with Tensile Mechanical Tests, FTIR, SEM, and ultrasound for thickness measurement. ASTM and Tappi standards are also followed to determine moisture, lignin, and ash content, ensuring a complete characterization of the modified material.<br/><br/><b>Goal</b>: <br/>The main objective is to waterproof the natural Cardulovica Palmata fiber by modifying its surface through the deposition of a polymer using low-pressure cold plasma technology.<br/><br/><b>Research lines</b>: <br/>nan
