Studies from Lulea University of Technology Further Understanding of Polyenes

January 21, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Polyenes. According to news originating from Lulea, Sweden, by NewsRx correspondents, research stated, "The properties of cellulose/polypropylene (PP) nanocomposites with n-octadecyl-modified bagasse nanofibers (MBNF) were compared to those with maleated polypropylene (MAPP) coupling agent. The nanocomposites were prepared by twin-screw extrusion with bagasse nanofiber (BNF) content varying from 2.5 to 10wt%."

Our news journalists obtained a quote from the research from the Lulea University of Technology, "The compression molded nanocomposites sheets were characterized regarding their tensile strength properties, dynamic mechanical thermal properties, crystallinity, water absorption, transparency and loss of strength due to composting in soil. As a compatibilizer to improve the tensile strength properties and transparency of PP/cellulose nanofibers nanocomposites, MAPP was more effective than n-octadecyl-modified cellulose nanofibers. The crystallinity of the nanocomposites was lower than that of neat PP except for those prepared using high loading of MBNF. Dynamic mechanical thermal analysis (DMTA) of the prepared materials showed that adding the different nanofibers (treated or untreated) resulted in better mechanical thermal properties above glass transition temperature (T-g) of PP. Water absorption capability in all nanocomposites was weakened while that in PP/MBNF was the lowest."

According to the news editors, the research concluded: "No significant differences were found between the nanocomposites with different kinds of nanofibers regarding the loss of their tensile strength after compositing in soil up to six months."
