Chemically modified chitin nanocrystals were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto chitin backbone via chlorination. Acetyl amino group was maintained in the reaction. The chemical structure and morphology of PHBV grafted chitin nanocrystals were characterized by Fourier transform infrared, Transmission electron microscopy and X-ray photoelectron spectroscopy...
Efficient procedures for the preparation of organic-soluble starch nanocrystal (SN) derivatives have been established with different degrees of substitution (DS). The resulting acetylated starch nanocrystals exhibit much improved solubility in common organic solvents such as N,N-dimethylformamide, acetone, carbon tetrachloride and toluene. The obtained nanocrystals were characterized by means of the...
