Abstract
In this work, we use the treated PF-ADF(2 ∼ 3 mm) as the reinforcing body(fiber) and the biodegradable PBS as the matrix. The different treated PF-ADF were mixed with PBS particles according to the mass percentage of 20:80, and C-PBS, C-DF/PBS, C-ADF/PBS and C-KDF/PBS were prepared by molding process. The influence of surface treatment on the microstructure and physical properties of the fiber were discussed and the mechanical properties of the composites were compared. Also the biodegradability of the different composite was analyzed. The results showed that most of the non-cellulosic materials such as pectin were removed from C-DF, but a certain amount of pectin remains on the surface. The surface of C-ADF appeared ‘S’ groove, and the groove on C-KDF was good continuity and deep. Compared with C-DF, the tensile strength of C-ADF and C-KDF increased by 5.08% and decreased by 3.58% respectively. Compared with C-PBS, the tensile strength and bending strength of C-KDF/PBS increased by 48.32% and 25.97% respectively, and the tensile modulus and bending modulus increased by 146.45% and 128.3% respectively. The changes of biodegradability of C-DF/PBS, C-ADF/PBS and C-KDF/PBS composites were consistent, but the change of weightlessness rate of C-KDF/PBS was the smallest. The more degraded and uneven the surface of the composite, the more obvious the decrease in contact angle.
