Aiming to systematically convert post-consumer plastics in building materials, we compounded recycled high-density polyethylene and sugarcane bagasse. We ranged the polymer/filler ratio from 100/0 to 60/40, and assessed the properties using optical microscopy, water absorption test, adhesion by tape test, low-field nuclear magnetic resonance, dynamic-mechanical analysis, and wide-angle X-ray diffractometry. The optical microscopy of the triturated bagasse showed the reduced and heterogeneous fiber sizes. The absorption and adhesion test showed that the polymer more heavily filled with bagasse can better absorb and anchor paint with organic solvent base. The dynamic-mechanical analysis and wide-angle X-ray diffractometry led us to believe that the bagasse fibers somehow structured the amorphous region amongst the crystallized lamellae of the polymeric matrix. We concluded that these composites have interesting properties to produce building materials.

Blending Method

Enormous amounts of plastic wastes are generated worldwide and the approaches related to plastic recycling or reusing have become the research focus in the field of composite materials. In this study, green composites were prepared via melt-blending method using high-density polyethylene (HDPE) sourced from plastic bags as a matrix and sugarcane bagasse (SCB) fiber as reinforcing filler. The effects of fiber loading (5, 10 and 15 wt%) and fiber modification on the mechanical and dimensional stability (weight gain by water absorption) properties of the green composites were investigated. Results showed that the inclusion of SCB fiber into recycled HDPE matrix increased the composite stiffness but decreased the mechanical strength and resistance to water absorption. With the fiber modification through alkali treatment, the mechanical strength was remarkably improved, and the modulus and water absorption of the composites were found to be reduced. From the finding, it can be concluded that the prepared green composites free of coupling agent could add value to the plastic and agricultural wastes, and serve a potential candidate to replace some conventional petroleum-based composites.

Synergistic Mechanism

Wood–plastic composites were prepared from poplar wood flour and high-density polyethylene (HDPE) by melt blending and injection molding techniques, using polyethylene-grafted glycidylmethacrylate (HDPE- g-GMA) as compatibilizer and γ-aminopropyltriethoxysilane as coupling agent. The scanning electron microscopy results showed that a stronger interfacial adhesion was formed between the wood flour and HDPE matrices during the combined use of γ-aminopropyltriethoxysilane and HDPE- g-GMA, while the X-ray photoelectron spectroscopy results showed that more HDPE chains are linked to the surface of poplar wood flour through the formation of chemical bonding in the presence of γ-aminopropyltriethoxysilane and HDPE- g-GMA. So, HDPE- g-GMA and γ-aminopropyltriethoxysilane showed a synergistic effect on the improvement of compatibility between the poplar wood flour and HDPE matrices and better mechanical properties of wood–plastic composites could be obtained. Furthermore, the thermogravimetric analysis results also indicated the synergistic effects to some extent. The synergistic mechanism of γ-aminopropyltriethoxysilane and HDPE- g-GMA was proposed on the basis of investigation results.
