While cellulose nanofiber-based bioplastics are of great interest for replacing synthetic polymer and glass materials, the main limitation is their low thickness, which makes them difficult for various applications. In this study, we fabricated millimeter-scale thick bioplastic composites, based on 2,2,6,6-tetramethylpiperidine-1-oxy-oxidized cellulose nanofibers (TEMPO-CNF) and epoxy resin, via sequential lamination processes. The glycerol as softener was added to TEMPO-CNF dispersion to prepare a thick TEMPO-CNF layer without shrinkage.

- Researchers are creating new materials for automotive weather-stripping and seal parts using poly(ether ester) elastomers instead of traditional rubber.
- The hardness of these new materials is adjusted by changing the composition of chain extenders while maintaining a fixed ratio of hard to soft segments.
- By partially replacing a standard chain extender with a fatty acid amide diol derived from soybean oil, they can also control the crystallinity and phase separation of the elastomers.
Gracilaria verrucosa, the red alga, is a suitable feedstock for biosugar production. This study analyzes biosugar production by the hydrolysis of G. verrucosa conducted under various conditions (i.
