Sažetak
Natural polymeric materials are interesting alternative to petrochemical products with potential application in almost all areas of human activities. However, despite the fact that the use of natural polymers based on polysaccharides, proteins and agricultural raw materials are very common, studies on potential use of acetylated cellulose isolated from wood as bio composite materials polymer matrix are very scarce. Specifically, acetylated cellulose application is almost exclusive to preparation of membranes for desalination, medical dialysis and filtration, while the commercial application of cellulose esters in terms of structural materials is at very low level, which regularly involves the synthesis and application of mixed cellulose esters (eg, cellulose acetate butyrate as material for tool handles and/or glasses frames). Wishing to expand the field of cellulose acetate application to bio composite wood material systems, the possibilities of cellulose isolation and its acetylation from two domestic commercially meagrely used wood species was investigated in this paper. Quantitative analysis of laboratory acetylation process beside chemical analysis of gained product by infrared spectroscopy (FT-IR) indicates the impact of water present in cellulose structure on values of mass increase, number of acetyl groups and the degree of acetylation. Results of thermogravimetric analysis (TGA) confirmed thus obtained results.
