Biorefinery lignin as filler material in polylactic acid composite

In natural world, lignin is unique and the most abundant renewable carbon source after cellulose, therefore, more applications of adding commercial value of lignin are needed. Polylactic acid (PLA), which has the second highest consumption of bioplastic in the world, is a biodegradable composite with widely application in industry. A filler adding into PLA can decrease the cost of the composite...

Preparation of Star-Shaped Polylactic Acid Drug Carrier Nanoparticles

Drug carrier biocompatible and biodegradable nanoparticles of about 15 nm were prepared by solvent evaporation technique from star-shaped poly(D,L-lactide) synthesized using dipentaerythritol as core and Tin (II) ethylhexanoate as catalyst.

Novel ammonia sensor based on polyaniline/polylactic acid composite films

We propose a new type of ammonia sensor based on composite film between polyaniline (emeraldine base) dissolved in dimethylformamide, and poly(DL-lactic) acid dissolved in chloroform. The two solutions were mixed in weight ratio of the components 1:1 and cast on Al2O3 substrate, on which silver electrodes were deposited previously. The active layer structure and morphology were examined by atom...
