| Abstract: | Due to the importance in economic and environmental benefits, marine biomass has gained increasing attention in recent years. In this work, marine biomass-based materials were prepared and characterized. Highly reinforcing cellulose nanocrystals (CNCs) with length of 1–2 μm and aspect ratio of ~75 were extracted from tunicates (t-CNCs), and CNCs with length of 100–300 nm and aspect ratio of ~15 from cotton (c-CNCs) were presented for comparison. In order to enhance interfacial interactions between CNCs and rubber, modification of natural rubber (NR) was conducted via epoxidation reaction to obtain epoxidized NR (ENR). Fully bio-based rubber nanocomposites were produced by latex mixing. Compared with NR nanocomposites, hydrogen bonding formed between ENR and CNCs, which led to homogeneous dispersion of CNCs and enhanced interfacial adhesion between them. Moreover, t-CNCs with longer length and larger aspect ratio facilitate filler entanglements, which led to higher reinforcing efficiency. Consequently, both hydrogen bonding and filler entanglements contributed to the improved mechanical properties of ENR/t-CNCs nanocomposites. |
