“…Because BC is very porous, polymers can permeate these pores, strengthening the BC-polymer interface and thus enhancing the mechanical properties of the composites. Li et al (2014) reported that the mechanical properties, water resistance, and thermal properties of WPC with BC were higher than WPCs, and Zhu et al (2016) also found the same results while the BC nanoparticles enhance BPCs. You et al (2014) reported a strong interfacial interaction between BC and polymers because the tanδ decreased with an increase in the BC content.…”

“…Bamboo carbonization could alleviate the high demand for wood charcoal and increase the utilization of bamboo resources. Furthermore, BC is a good reinforcement material for all types of polymers (Lou et al 2007;Kittinaovarat and Suthamnoi 2009;Ho and Lau 2014;You and Li 2014;Ho et al 2015), wood-plastic composites (WPCs) , and BPC (Zhu et al 2016). In addition to being a stiff material, BC also exhibits unique properties, including high porosity, high moisture resistance, odour control, bacterial and fungal growth inhibition, and heavy metal absorption (Kittinaovarat and Suthamnoi 2009;Ho and Lau 2014).…”

The use of bamboo charcoal (BC) was investigated as a filler in bambooplastic composites (BPCs) to achieve improved water resistance, physical-mechanical properties, and reduced hydrophilicity. The influence of the BC content and size on the water absorption, contact angle, density, and mechanical properties of bamboo flour/low-density polyethylene (LDPE) composites was tested. Scanning electron microscopy was used to analyse fractured and flat composite surfaces. The results indicated that the BC increased water resistance, achieving optimal results at 8% content. The BC particles that ranged in size from 60 to 100 mesh were more water-resistant than other sized BC. The water contact angle increased with an increase in the BC content or a decrease in the particle size. These results indicated that BC reduced the composite hydrophilicity and that the smaller BC particles improved this effect. The BC strongly connected with the LDPE composites, and the BC contents below 12% improved the flexural properties and increased the density of the BPCs. Also, the impact strength of the BPCs decreased dramatically with a decrease in the BC particle size. These results demonstrated that the integration of BC with BPCs resulted in strengthened water resistance and physical-mechanical properties and reduced hydrophilicity.

Bamboo-plastic composites (BPCs) are manufactured via hot pressing and extrusion or injection moulding using thermoplastics and bamboo instead of wood (Yeh et al. 2009;Wu et al. 2013). BPCs are widely used in decorations, outdoors, and as non-structural components of buildings (Xian et al. 2015) because they are biodegradable, renewable, and environmentally friendly materials (Zhou et al. 2015a). However, the interface between the polar, hydrophilic bamboo fibres and the non-polar, hydrophobic low-density polyethylene (LDPE) is weak, which leads to the formation of many gaps and pores between the two materials. This incompatibility results in poor mechanical properties and renders the composites vulnerable to water penetration and fungal attack (Hosseinihashemi et al. 2011;Mbarek et al. 2013).

Another method of eliminating gaps is filler addition, which is a simple and low-cost way to effectively improve the composite morphology and mechanical properties.

In this study, ultrafine bamboo-char (UFBC) with different particle size was introduced into polypropylene (PP)/bamboo particle (BP) composites to improve the mechanical, thermal, and moisture resistant properties. PP/BP/UFBC ternary composites of different weight ratio were fabricated by melt blending and hot compression molding. Results showed that with UFBC content increasing, mechanical properties of composites gradually increased, and the good tensile strength of 29.12MPa and 34.15MPa was obtained when the ratio was 70/5/25 and 70/0/30, respectively, which improved by 141% and 182% than that of pure PP. Further, especially for finer UFBC, there was an obvious enhancement in flexural strength from 33.71 MPa to 54.14 MPa corresponding to the ratio of 70/20/10 to 70/ 5/25. The improvement related to matrix-filler adhesion was also demonstrated by SEM. Crystallization temperature and melting temperature exhibited 8.78C and 4.68C higher than PP/BP composites, respectively. Moisture resistance was significantly improved when over 20 wt% UFBC was added. POLYM. COMPOS., 00:000-000,

Natural fiber‐reinforced composites are showing promising results compared to synthetic fiber‐reinforced composites. Therefore, the present work highlights the utilization of chemically treated bamboo‐fiber (BF) for the preparation of bamboo‐fiber high‐density polyethylene composites (BF/HDPE). Both virgin HDPE and recycled HDPE (r‐HDPE) are considered for the preparation of bamboo fiber (BF) composite and their physico‐mechanical properties are evaluated. On alkali and stearic acid treatment, more fibrillation and surface roughness are observed in the BF surface which created more contacting surfaces to improve the interfacial interaction between the BF and HDPE & r‐HDPE matrix. The tensile strength of stearic acid‐treated BF/HDPE is increased by 9.26% and stearic acid‐treated BF‐ rHDPE shows an increment of 16.5%. Similar observations are made for impact strength which confirms the improved dispersion of BF in both matrices. The improved interfacial bonding between BFs and HDPE matrix and good dispersion between fibers and matrix can further be confirmed through the SEM images of composite fractured surfaces and FTIR analysis.Highlights Surface of BF has been modified by NaOH and stearic acid treatment. Modified fibers are used as reinforcement in virgin and r‐HDPE composites. Stearic acid treatment enhances the tensile strength of composites. Surface modification has significant impact on r‐HDPE composites.
