Surface grafting of cellulose nanocrystals with poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

- A series of biodegradable PHCN copolymers were successfully prepared.
- The copolymers with the different length and grafting density of PHBV side chains could be tailored.
- The improved thermal stability and hydrophobicity of the copolymers could be obtained.
- The hydrophobic copolymer with high thermal stability can be reinforcing filler for nanocomposites.
