Therefore the aim of this resarch is to study how to synthesis cassava shell based biodegradable plastic and to analyse the effect of kitosan addition on cassava shell based biodegradable plastic properties There are three basic characterization processes performed to analyse the sample properties i e mechanical test FTIR and
This thesis describes the synthesis characterization and enzyme degradation of a novel biodegradable copolymer comprising poly(L-glutamic acid) and polylactide segments First the preparation of protected poly(y-benzyl-L-glutamate) (PBLG) bearing NH2 group at both ends with narrow molecular weight distribution was conducted
Outline We have previously synthesized soft and flexible polymer nanotubes and shown that they release anti-cancer drugs for a period of one month These early studies have proved the concept that high aspect ratio materials with their unique properties can allow long-term drug release Unlike carbon nanotubes these polymer nanotubes have shown no toxicity in in vitro cultures showing that
