“…In our previous work, PMHS was used for surface hydrophobic modi cation of BF to improve the mechanical properties of BPC (Xiao et al 2021). The most interesting nding was that PMHS could play contrary roles in adjusting the mechanical properties, in which PMHS with backbone structure of -[Si(H)CH 3 -O] m -serve as a hard interface layer between BF and HDPE while that of -[Si(H)CH 3 -O] m -[Si(CH 3 ) 2 -O] n -played as a soft interface layer.…”

Bamboo our/high-density polyethylene (BF/HDPE) composite was strengthened and toughened simultaneously by the surface encapsulation of BF with poly(methylhydrogen)siloxane(PMHS) and Ethylene Propylene Diene Monomer (EPDM). An elastic PMHS@EPDM shell was fabricated on BF surface by successively spraying PMHS/hexane and EPDM/hexane solutions onto BF, based on the dehydrogenation and addition reaction of PMHS with BF and EPDM. It was found that surface encapsulation of wood at high PMHS content would simultaneously increase the strength and toughness of BF@PMHS/HDPE composite. The tensile strength and impact strength were increased by 54.2% and 9.9%, respectively as PMHS content was 3.3%. Furthermore, an encapsulation of BF@PMHS with EPDM further increased the strength and toughness by 5.1% and 14.7%. Compared with the pristine BF/plastic composites (BPC), the tensile, exural and impact strength of modi ed BPC increased by 62.1%, 28.0% and 26.1%. The changes in the microstructure of the interface between BF and HDPE as a function of encapsulation of PMHS and EPDM and the relationship between chemical structure, microstructure and mechanical properties were discussed in detail. This work gave a novel MAH-free method for strengthening and toughening BF/HDPE or wood our/high-density polyethylene (WF/HDPE) composites.

As environmental stress is caused by using fossilbased plastics, bamboo fibers (BFs), as one of the important natural materials, have received more and more attention. However, their poor thermal stability and lack of functionality largely limit their wider application. In this work, the electroless plating method was used to improve the thermal stability of the BFs and impart this function. It was found that the amount of metal deposition was the main factor affecting the thermal stability of BFs. A critical value existed, above which the surface of BFs could be completely covered by a plating layer, resulting in much enhanced thermal stability. The initial degradation temperature of BFs could be improved by 31 °C, as detected by TG. XRD and TG-FTIR spectroscopy were used to further understand the observed increase in thermal stability induced by electroless plating. It is suggested that the coating layer could block the invasion of external O 2 , thus delaying the degradation time and the pyrolysis rate. It is also very interesting to find that hygroscopicity and electrical and magnetic properties could be simultaneously improved. Our work provides a new method for the modification of BFs, which is important for the application of BFs.

The mechanical properties of polymer-based composites are generally determined by the interfacial adhesion between the inorganic component and the polymer itself. In this work, high-density polyethylene (HDPE) composites were prepared with polydopamine(PDA)-modified short basalt fibers (D-BF) as an inorganic filler, in which the interface between HDPE and D-BF was mediated by maleic anhydride-grafted polyethylene (PE-g-MAH) and maleic anhydride-grafted poly(ethylene-co-octene) elastomer (POE-g-MAH). The adding mass ratio of both the compatibilizers had a significant effect on the mechanical properties of the prepared HDPE/D-BF composites. When total 5 wt% of both PE-g-MAH and POE-g-MAH with a mass ratio of 1/3 was intro-
