Halloysite-Chitosan based Nano-Composites and Applications


Halloysite-Chitosan based Nano-Composites and Applications

G. Santhosh, B. Sowmya

Chitosan is the most abundant and excellent natural polymer (PMR). The wider usage of chitosan is because of its antimicrobial, non-toxic, biocompatible and biodegradable nature. Chitosan is extracted from crustaceans and squids. Chitosan has been extensively studied in the field of wastewater treatment and biomedical applications. Halloysite nanotube (HNT) is a sort of aluminosilicate nano-clay, famous for their high aspect ratio and hallow configuration, HNT as a nano-filler for polymer matrix can be profitably utilized. HNT with the molecular formula, H4Al2O9Si2·2H2O have unique tubular structure make them suitable as nano-containers with the intention to store and adsorb with abundant –OH groups. The use of HNT can provide high mechanical strength, high thermal stability and bio-acceptability. With the incorporation of nanosized halloysites nanotubes into chitosan matrix generally leads to desired property enhancement along with the changes in the microstructure. Amongst the most likely available natural materials, the chitosan and halloysite are attractive ones because of their nontoxic and eco-friendly nature. The halloysite was extensively studied as a carrier material in many drug delivery systems, catalytic support, scaffold for tissue engineering and as a nanofiller for food packaging application. In this chapter, the application of chitosan and HNT in the real world are postulated in order to give insights for future studies.
