Despite the excellent properties of room-temperature-vulcanized silicone rubber (RTVSR), such as good temperature resistance, low toxicity, and low cost, its industrial application is limited owing to its poor mechanical properties. Herein, we employed cellulose nanocrystals modified by acid hydrolysis and reaction with 3-isocyanatopropyltrimethoxysilane (ICNCs) as the cross-linking agent to reinforce...
Polymers from renewable biomass are viable supplements for synthetic polymers. In this study, cellulose nanocrystals (CNs) were used as nanofillers to improve properties of rosin-based waterborne polyurethanes (RWPU). The morphology, structure, thermal, and mechanical properties of the RWPU/CNs nanocomposites were investigated. It demonstrated that CNs were compatible with RWPU and dispersed homogeneously...
Synthesis of Ag nanopaticles was carried out with carboxylated cellulose nanocrystals as the scaffolds by reducing metallic cations using NaBH4. Ag particles with a size less than 10 nm were readily prepared and dispersed well. The carboxyl and hydroxyl groups of carboxylated cellulose nanocrystals supplied a coordination effect to adsorb metallic cations and Ag nanoparticles, which prevent the aggregation...
