O homogeneously disperse in PHS matrix, displaying no apparent aggregation. Each PHS/CNC composites and PHS showed a equivalent very good thermal stability, with all the decomposition temperature of about 360 C. Under various crystallization circumstances, CNC enhanced the crystallization of PHS. On the 1 hand, CNC slightly increased the melt crystallization temperature in the course of a cooling approach at five C/min. However, CNC enhanced the isothermal crystallization rate of PHS in a temperature array of 41 to 47 C. Growing crystallization temperature steadily decreased the crystallization RP101988 In stock prices of both PHS/CNC composites and PHS; in addition, the larger the CNC content material, the quicker the crystallization price of PHS/CNC composites. For instance, 1 wt of CNC remarkably reduced the crystallization half-time of PHS from 34.two to 12.two min. The Avrami method effectively described the isothermal crystallization kinetics of PHS/CNC composites and PHS. Regardless of CNC content material and crystallization temperature, the crystallization mechanism did not modify. The spherulitic morphology revealed an clear reduce within the size of PHS spherulites, offering direct proof on the nucleating agent effect of CNC. Moreover, CNC didn’t modify the crystal structure of PHS. As a reinforcing nanofiller, CNC AAPK-25 Description improved the mechanical house of PHS, especially the Young’s modulus and yield strength. PHS/CNC composite with 0.5 wt of CNC exhibited the comparable mechanical properties to these of other biodegradable polymers which include PCL, PBA, and PBS, displaying a Et of 430.9 11.8 MPa, a of 16.87 0.43 MPa, plus a of 398.2 32.4 . In sum, the crystallization and mechanical property of PHS may well be enhanced by low contents of CNC, supplying a suitable method to adjust the physical house and extend the wider sensible application of biodegradable polymers.Author Contributions: S.P. investigation; writing–original draft preparation; Z.Q. supervision; writing–review and editing; funding acquisition.
