High performance fibers and improved interfacial interaction can enhance the properties of polymer composites. Herein, microcrystalline cellulose (MCC) was oxidized by H2O2/CuSO4, a new Fenton process, to achieve MCC (OCNCs) with 16 ± 1% carboxyl content. Noteworthy, thermal stability OCNCs superior CNCs prepared acid hydrolysis. Interestingly, primary alcohol groups were selectively achieved 1...

carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film was produced through casting. cellulose nanowhisker (cnw) was produced by means of acid hydrolysis of cotton linter and cmc-pvoh-cellulose nanowhiskers through which fully degradable bionanocomposites were prepared. prepared nanowhisker suspension contained rod like particles averaging lengths of 240 nm and diameters of 13 nm. an...
