Review of Recent Development on Preparation Properties

CNCs were modified with silane coupling agent KH-550 as a reinforcing agent and biopolyester poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3 4)HB)/STCNW nanocomposites were prepared by the solution casting method The STCNCs enhanced hydrophobicity and facilitated the crystallization of P(3 4)HB which greatly improved the tensile strength and elastic modulus
