New Nanocomposites Findings from State University Reported

June 3, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Nanocomposites are discussed in a new report. According to news reporting from Kolkata, India, by NewsRx journalists, research stated, "Graphene oxide (GO) was synthesized by Hummer's method and characterized by using Fourier transform infrared spectroscopy and Raman spectroscopy. The as synthesized GO was used to make GO/hydroxypropylmethylcellulose (HPMC) nanocomposite films by the solution mixing method using different concentrations of GO."

The news correspondents obtained a quote from the research from State University, "The nanocomposite films were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and thermo-gravimetric analysis. Mechanical properties, water absorption property and water vapor transmission rate were also measured. XRD analysis showed the formation of exfoliated HPMC/GO nanocomposites films. The FESEM results revealed high interfacial adhesion between the GO and HPMC matrix. The tensile strength and Young's modulus of the nanocomposite films containing the highest weight percentage of GO increased sharply. The thermal stability of HPMC/GO nanocomposites was slightly better than pure HPMC."

According to the news reporters, the research concluded: "The water absorption and water vapor transmission rate of HPMC film was reduced with the addition of up to 1 wt% GO."
