Abstract
How to improve the interfacial compatibility between polar fibers and non-polar polymer matrices is still a challenge for the application of natural fiber/polymer composites. In this study, the jute fibers (JF) was firstly treated by coating sodium lignosulfonate (SL) layer, then the JF-SL/polypropylene (PP) composite was fabricated by injection molding technique. The morphology, surface chemical property, surface energy, mechanical properties of JF and JF-SL, as well as the mechanical properties of JF/PP and JF-SL/PP composites were systematically studied. The results showed that the SL coating layer successfully formed on the surface of JF, and the dipole bond and hydrogen bond interaction occurred between the SL and JF. Compared with JF/PP composite, the tensile modulus, tensile strength, flexural modulus and flexural strength of JF-SL/PP composite increased by 8.25%, 16.79%, 16.87% and 19.71%, respectively, due to the enhancement of the interfacial binding force between JF-SL and PP matrix. These results indicate that SL possesses great potential to be used as a compatibilizer to effectively improve the mechanical properties of JF-SL/PP composite. It could provide an reference basis for the feasibility of SL used as a compatibilizer for natural fiber/polymer composites.
