Lignocellulosic Biodegradable Polymer Composites

Cellulose fiber-reinforced biodegradable polymers result in completely biodegradable composites, the so-called green composites . Interest in these composites has increased in recent years, with a corresponding increase in the studies looking into the weathering properties of these composites. 

In summary, susceptibility to weathering has clearly been shown to be significant for fully bio-based composites, and improved resistance to environmental attack will be necessary for fully bio-based composites to be considered viable replacements for any long term applications where materials are subject to hostile environmental conditions such as in the building sector.

Computational chemistry is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry, incorporated into efficient computer programs, to calculate the structures and properties of molecules and solids. The lignocellulosic materials are mainly made up of a complex network of three polymers cellulose, hemicellulose, and hgnin. Due to their hydrophilicity, biodegradability, biocompatibility and low toxicity, hemicelluloses have been studied by numerous research groups with respect to their use as composites in biomedical apphcations.
