Researchers at University of Tabriz Have Reported New Data on Hydroxides (Preparation and properties of carboxymethyl cellulose/layered double hydroxide bionanocomposite films)
By a News Reporter-Staff News Editor at Biotech Week -- A new study on Hydroxides is now available. According to news reporting originating from Tabriz, Iran, by NewsRx correspondents, research stated, "Solution casting method was employed for preparing of carboxymethyl cellulose/layered double hydroxide (CMC-LDH) bionanocomposite films with LDH content ranged from 0 to 8 wt%. The synthesized nanocomposite films were characterized using FTIR, XRD, TEM and SEM analytical methods."
Our news editors obtained a quote from the research from the University of Tabriz, "XRD and TEM analysis revealed a partially exfoliated structure for nanocomposites with LDH content up to 3 wt%. However, for LDH contents higher than 3 wt%, nanocomposites formed an intercalated structure. Incorporation of LDH significantly decreased water vapor permeability (WVP) of the bionanocomposite films up to 37%. Addition of the LDHs into the CMC matrix is accompanied by a decrease in the film transparency. Mechanical properties of CMC-based films were improved significantly by addition of LDH particles."
According to the news editors, the research concluded: "CMC-LDH nanocomposite film with 3 wt% LDH showed a 148 and 143% increase in the tensile strength and tensile modulus, as well as a 62% decrease in elongation in comparison with the pure CMC film."
