Study Data from Beijing Forestry University Update Knowledge of Lactates [Thermal, Mechanical, and Degradation Properties of Nanocomposites Prepared using Lignin-Cellulose Nanofibers and Poly(Lactic Acid)]

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Lactates. According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "A variety of nanocomposites were prepared using lignin-cellulose nanofibers (L-CNF) and poly(lactic acid) (PLA) via a solvent casting process. Acid hydrolysis and high-pressure homogenization processes were used to produce L-CNF from unbleached kraft pulps."

Our news journalists obtained a quote from the research from Beijing Forestry University, "Tensile tests were conducted on thin films, and the nanocomposites containing 3 wt. % L-CNF showed a 32.4% increase in tensile strength compared to that of neat PLA. Dynamic mechanical analysis showed that the tensile storage modulus increased in the viscoelastic temperature region with increasing L-CNF content in the nanocomposites. Thermogravimetric analysis (TGA) showed that all the materials investigated were thermally stable from 25 to 310 degrees C. Differential scanning calorimetry (DSC) showed a decrease in the cold crystallization temperature. A positive effect on the crystallization of PLA polymers in the nanocomposites with added L-CNF was observed using DSC and X-ray diffraction (XRD) analysis."

According to the news editors, the research concluded: "The degradation profiles and swelling ratios of the nanocomposites improved."
