Research progress in wood-plastic nanocomposites

Abstract

The interest towards wood-plastic composites (WPCs) is growing due to growing interest in materials with novel properties, which can replace more traditional materials, such as wood and plastic. The use of recycled materials in manufacture is also a bonus. However, the application of WPCs has been limited because of their often poor mechanical and barrier properties, which can be improved by incorporation of the reinforcing fillers. Nano-sized fillers, having a large surface area, can significantly increase interfacial interactions in the composite on molecular level, leading to materials with new properties. The review summarizes the development trends in the use on nanofillers for WPC design, which were reported in accessible literature during the last decade. The effect of the nanofillers on the mechanical properties, thermal stability, flammability and wettability of WPC is discussed.

Properties of Vulcanized Polyisoprene Rubber Composites Filled with Opalized White Tuff and Precipitated Silica

“…Higher amount of nanoparticles tends to increase the surface interaction among themselves and thereby enhanced the tendency for agglomeration. At lower loading of SiO 2 , the nanoparticles were well dispersed and thereby increased the surface area for interaction [ 36 ]. NR/OWT (100/20) rubber blend has maximum tensile strength values.…”

“…Well-dispersed nanoparticles resulted in difficulties of heat and mass transfer through the material, thereby preventing fast degradation. Well-dispersed filler acts as a mass transport barrier to oxygen and volatile decomposition products [ 36 ]. The tensile strength is a complex function of the nature and type of cross-link's, cross-link densities, the chemical structure of the used elastomers, and the changes associated with degradation.…”

Effects of different filler types on decay resistance and thermal, physical, and mechanical properties of recycled high-density polyethylene composites

“…They have low density, good thermal insulation, and mechanical properties, as well as being inexpensive. In addition, they exhibit moisture resistance and dimensional stability due to their polymer matrix characteristics [8,9]. Furthermore, with their properties of enhanced strength, rigidity, elasticity, non-abrasiveness, ready availability, etc., these materials have a wide range of application.…”

Impact of lithium chloride and in‐situ grafting on the performance of microcrystalline cellulose‐filled composites based on polyamide 6/high‐density polyethylene

“…In the past two decades, wood plastic composites (WPCs) have attracted much attention in many fields, such as decoration, landscaping and automobile industry . The composites based on high‐density polyethylene (HDPE) have been widely applied in the market, which is attributed to some outstanding advantages of HDPE, such as excellent toughness, good processability, and low cost.…”
