摘要

Natural fibers have attracted a great deal of attention as an alternative to synthetic reinforcement with polymer composites, primarily because they are biodegradable and produce little environmental impact. In the present work, the extraction of fibers from Typha angustifolia was performed, followed by chemical treatments to improve their interfacial compatibility with composite matrices. To eliminate lignin, hemicellulose, and surface contaminants, mature cattail plant fibers were treated alkalinely with a mild sodium hydroxide solutionBoth untreated and treated fibers were examined using Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy, and Thermogravimetric Analysis. The treatment led to evident surface roughening and partial removal of amorphous constituents, causing an increase in crystallinity and enhancement of thermal stability. These changes evidenced a potential for improved interfacial adhesion when combined with biodegradable polymers. In general, Typha angustifolia fibers presented promising characteristics to be used as renewable reinforcement in the fabrication of lightweight and ecological composite materials.
