“…This continuity is analogous with the one observed on the composite when the filler is treated with a coupling agent . A previous study on polyamide matrix composites filled with bamboo flour showed that this kind of treatment is not necessary with the PA 11 composite due to the formation of hydrogen bonds between the polymer and the fibers …”

“…This study shows that the presence of bamboo fibers does not significantly modify the thermal behavior of the crystalline phase of PA 11 in PA 11/BF composites. The shape and magnitude of the melting peak of PA 11 are unmodified . Physical interactions in the amorphous phase of PA 11/BF composites inhibit the physical aging observed in the amorphous phase of bulk PA 11.…”

This study is devoted to the analysis of the properties of continuous bamboo fiber (BF)-reinforced polyamide 11 (PA 11) composites. The SEM observations highlighted continuity between BFs and the polymeric matrix showing a high density of hydrogen bonds. The comparative calorimetric study of the matrix and its composites showed that the crystallinity of PA 11 was not modified by the presence of bamboo fibers. The physical aging observed in PA 11 is no more observed in composites due to physical interactions between PA 11 and BFs. The mechanical properties were investigated by tensile strength and dynamic mechanical analysis. The introduction of BFs enhanced Young's modulus of the matrix by a factor of 10. The presence of BFs also improved the storage shear modulus G 0 over the whole temperature range.

“…As an extension of wood-plastic composites (WPCs), bamboo-plastic composites (BPCs) are a kind of biomass-plastic mix that consists of a variety of components, including bamboo fibers (BFs) and thermoplastic materials (e.g., polyethylene, polypropylene, polyvinylchloride, etc.) [2][3][4]. BPCs are intriguing due to their promising features with regard to low density, good thermal insulation, and good mechanical properties.…”

“…Among various nanomaterials, halloysite nanotubes (HNTs) have been incorporated as a new type of green, unique, and promising reinforcing filler for thermosets and thermoplastic polymers [19][20][21]. HNTs (Al 2 Si 2 O 5 (OH) 4 •nH 2 O), a hydrated polymorph of 1:1 rolling phyllosilicate clay, are readily obtainable and biocompatible, providing great advantages compared with other traditional fillers such as carbon nanotubes [22,23]. HNTs can be readily dispersed in most polymer composites due to their rod-like geometry, low hydroxyl density on the surface, and lack of intertwining [24].…”

Bamboo-plastic composites (BPCs) as new biomass-plastic composites have recently attracted much attention. However, weak mechanical performance and high moisture absorption as well as low thermal stability greatly limit their industrial applications. In this context, different amounts of halloysite nanotubes (HNTs) were used as a natural reinforcing filler for BPCs. It was found that the thermal stability of BPCs increased with increasing HNT contents. The mechanical strength of BPCs was improved with the increase in HNT loading up to 4 wt% and then worsened, while the impact strengths were slightly reduced. Low HNT content (below 4 wt%) also improved the dynamic thermomechanical properties and reduced the water absorption of the BPCs. Morphological studies confirmed the improved interfacial compatibility of the BPC matrix with 4 wt% HNT loading, and high-concentration HNT loading (above 6 wt%) resulted in easy agglomeration. The results highlight that HNTs could be a feasible candidate as nanoreinforcements for the development of high-performance BPCs.

“…So far, a wide variety of surface modification techniques based on physical or chemical means have been developed by the industry and academia. [2][3][4][5][7][8][9][10][11][12][13] Among these methods, the main one is to add coupling agents or compatibilizers into the polymer matrix. For polyolefin composites, the most often used compatibilizers are maleic anhydride-grafted PE or PP.…”

In order to improve the interfacial interaction between poly(ethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate) (PETG) and bamboo flour, the surface of bamboo flour (BF) was modified with methyl methacrylate (MMA) using the electron transfer (AGET) atom transfer radical polymerization (ATRP) method. The grafted BF was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis. The MMA groups had been successfully grafted onto the BF surface and the contact angle of the grafted BF was as high as 130°. The maximum flexural strength was determined to be 72 MPa for the composite containing 20 wt% modified BF, which was higher than that of the composite containing 20 wt% original BF (62 MPa). Also, the decrease in loss factor indicated that the grafting modification improved the compatibility between PETG and BF, and this conclusion was also confirmed by SEM. The results have great practical significance for the application of PETG/BF composites.
