“…In the present work it was noticed that KH550 treatment led to a small increase in crystallinity (Xc) from 40.71 % to 41.82 %. This trend is similar to KH550-modified corn fiber/PLA composites, where Xc increases from 37.75 % to 41.49 %, as measured by DSC (Luo et al 2014) The findings in this paper imply that the amorphous region on bamboo flour was partly destroyed during silane sizing, while new crystalline areas were harvested after rearrangement among macromolecular chains (Zhao 2012;Wei et al 2014). In addition, some impurities with lower crystallinity were also removed from fibers during modification (Lu et al 2014).…”

“…This process was different from silane A-171-modified poplar veneer, KH550-treated corn fiber, and KH560-modified bamboo cellulose, in which silanol is demonstrated to react with hydroxyl groups on cellulose (Fang et al 2014;Lu et al 2014;Luo et al 2014). In general, the crystalline part of natural cellulose chains represents the most potential agents for reinforcing polymer (Ng et al 2015).…”

“…In addition, some impurities with lower crystallinity were also removed from fibers during modification (Lu et al 2014). Typically, the filler would simultaneously contribute to nucleating (increasing Xc) and exhibit a hindrance to migration and diffusion of polymeric molecular chains (decreasing Xc), which are two competing factors that dominate the crystallization process within a composite system (Luo et al 2014). In this sense, modified bamboo flour with better interfacial compatibility would be more beneficial to the arrangement of an HDPE chain, resulting in a higher Xc for the composite.…”

“…On one hand, enhanced intensity near 2900 cm -1 and 1100 cm -1 after modification would be respectively assigned to stretching vibrations of C-H and Si-O-C (Fang et al 2014;Lu et al 2014), in which the former would be raised by adding KH550 while the latter would be formed via reaction with silanol, thus proving the introduction of silane and occurrence of grafting. On the other hand, diminished intensity around 1700 cm -1 for modified sample would be an indication of lignin aldehyde carbonyl C=O stretching vibration (Luo et al 2014), which would be concerned with decreased concentration due to grafting behavior, thereby further explaining the reaction site. Consequently, bamboo and KH550 would interact on the aldehyde group of lignin, thus achieving the compatibilization.…”

“…However, to the authors' best knowledge, the application of silane to this combination has been barely reported on, with the loading level of natural fiber among previous works generally lower (<50%), thereby failing to make full use of potential resources (Fang et al 2014;Lu et al 2014;Luo et al 2014;Yeh et al 2015). Since data findings and study conclusions (especially the mechanism regarding interfacial bonding) may change greatly under different materials and processes, targeted research on this silane modified bamboo plastic composite is undoubtedly very necessary (Zakikhani et al 2014).…”

To blaze new trails for utilizing forestry processing residue, higher plant content biocomposites were proposed based on a combination of moso bamboo flour/silane KH550/high density polyethylene (HDPE), and the materials were characterized by diffractometry, spectroscopy, microscopy, and calorimetry. During surface modification, reactions between bamboo and silane occurred on the lignin aldehyde group. After 6 wt% KH550 treatment, crystallinity of bamboo was increased by 1.11 %, and melting temperature and enthalpy of the composite rose by 2.37 °C and 5.27 J/g, agreeing with improved interface morphology. Increasing in thickness from 3 to 9 mm, the physical and mechanical properties of composite were improved overall. Bamboo content caused the biggest influence, while thickness swelling exhibited the greatest susceptibility. Increasing the bamboo ratio boosted flexural and tensile properties, but it compromised toughness and water resistance, while silane and moulding parameters featured complicated relationships regarding performances. Combining an artificial neural network (ANN), KH550 3 wt%, moulding temperature of 180 °C, and a time of 8 min endowed 9 mm composites of 70 wt% bamboo with performance comparable to load bearing MDF in GB/T 11718.

A growing variety of composites utilize natural plant fibers with naturally occurring veins structured hierarchically in an effort to reduce dependence on petroleum‐based materials. In this article, ramie fibers were extracted by alkaline delignification. Then, ramie fibers and PP matrix, were prepared in filament form and an amino‐silane coupling agent KH550, and maleic anhydride grafted polypropylene were added to improve interfacial compatibility. Ramie fiber/polypropylene fiber‐reinforced polymer composites (FRC) were prepared by hot pressing after using a carding machine. This method preserves the structure and length of ramie fibers to a large extent, thus greatly improving the mechanical properties of the material. After optimization, the FRC prepared from plant fibers of 2 cm length and 60% content had a density of 0.95 g/cm3, showed an increase in tensile and flexural strength of 276% and 339%, respectively, compared to the pure PP matrix. The specific strength of the FRC in the work was higher than galore FRC prepared from talc, carbon fiber, other plant fibers, and so forth. The FRC has a wide range of potential applications due to its own low‐cost, lightweight, and high‐performance, and is highly feasible in replacing the current polymers in the preparation of numerous everyday items.Highlights The preparation method of FRC resulted in a more complete fiber length and structure. The mechanism to improve the interfacial compatibility of RF and PP is discussed. The effect of varying fiber length on the FRC mechanical properties was investigated.
