Thermoset nanocomposites from waterborne bio-based epoxy resin and cellulose nanowhiskers

Thermo-Gravimetric Analysis of Various Ratio of Blended Phenolic and Epoxy Composites

“…Initially pure epoxy and blended composites have shown weight loss between 100-200°C, it showed epoxy resin has some free hydroxyl molecules and dehydration of secondary alcoholic groups and evaporation of physically weak and loosely bound moisture on the surfaces of the composites [16]. The thermal degradation of pure epoxy was observed above 300°C, the decomposition of pure epoxy was due to the pyrolysis and decomposition of aromatic groups of the epoxy network and the degradation of aliphatic amine curing agent owing to low breaking energy of C N bond, as reported by other findings [17,18]. All blended composites showed thermal degradation between 100-150°C, due to dehydration process and weight loss was measured between 5.54-6.04% that is very less.…”

Effects of processing on the properties of chitosan/cellulose nanocrystal films

“…When T g values of samples are11 compared with each other, it is observed that addition of CN increases slightly glass transition 12 temperature. Other studies also reported T g increasing effects from adding cellulose to the13 biopolymers (Anglés & Dufresne, 2000; Azeredo et al, 2010; Alemdar & Sain, 2008).…”

Sodium alginate/cellulose nanocrystal fibers with enhanced mechanical strength prepared by wet spinning

“…Over the last decade, different polymer/CN composites have been investigated. [13][14][15][16] Based on the Raman spectroscopy analysis, it was determined that CNs were unoriented in the nanocomposite films and highly aligned in the nanocomposite fibers. Nanocomposite fibers with highly aligned CNs showed higher interfacial shear strength than nanocomposite films with isotropic CNs.…”
