Abstract
Green composites are increasingly promoted for sustainable development considering the growing awareness of environmental and waste management issues. Recent advances in natural fiber development, and nanocomposites research area generate significant opportunities for obtaining materials from renewable resources with improved properties and suitable for different applications. Green composites are made from both renewable resource-based polymers (biopolymers) and bio-fillers (including nano-type fillers), with a positive environmental impact. Green composites based on biopolymer matrix (plasticized starch) have been obtained by combination with various bio-fillers (beech wood sawdust, fir tree needles, beech wood lignin). Their structure and properties were further investigated through Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), and TG/DTG/DTA simultaneous thermal analysis methods, as well as by water uptake and opacity measurements. The results are presented in this chapter.
