Recent Research from Sri Jayachamarajendra College of Engineering Highlight Findings in Nanocomposites

June 3, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanocomposites have been published. According to news reporting originating from Karnataka, India, by NewsRx correspondents, research stated, "Hydroxypropyl methyl cellulose (HPMC) based hybrid nanocomposites reinforced with bacterial cellulose nanocrystals (BCNC) and silver nanoparticles (AgNPs) had been prepared and characterised. BCNC was capable of improving the tensile strength and modulus of HPMC, but they made the film more brittle."

Our news editors obtained a quote from the research from the Sri Jayachamarajendra College of Engineering, "The addition of AgNPs along with BCNC, helped to regain some of the lost elongation properties without affecting other properties. Moisture sorption analysis proved that the hydrophilicity of the nanocomposite decreased considerably by the addition of these nanomaterials. Several mathematical models were also used to fit the experimental sorption results. A unique combination of two nanomaterials was highly effective in overcoming certain limitations of nanocomposites which uses only one type of nanomaterial."

According to the news editors, the research concluded: "This type of hybrid nanocomposites with superior properties is expected to be useful in eco-friendly food packaging applications."
