“…The TGA and DTG curves of HDPE showed only a single decomposition step between 453.4 °C and 486.5 °C. The NBC-BPC1 composites presented intermediate thermal stability between neat HDPE and BF, which suggests that the addition of BF only slightly improved the thermal stability, as previously noted (Chattopadhyay et al 2011). The NBC-BPC1 composite demonstrated two decomposition stages.…”

To illustrate the effects of nano-bamboo charcoal (NBC) on the properties of bamboo plastic composites (BPC), nano-bamboo charcoalbamboo plastic composites (NBC-BPC) were prepared at 0%, 2.5%, 5%, 7.5%, 10%, and 12.5% (w/v) NBC and characterized. The effects of NBC on the water absorption, fractured surfaces, mechanical properties, and thermal properties of the composites were investigated. NBC had strong interfacial interaction in the BPC, which greatly improved the interfacial adhesion of bamboo flour (BF) and high-density polyethylene (HDPE). The water resistance, flexural strengths, and tensile strengths of the composites were enhanced compared with traditional BPC when the volume of NBC reached a specific loading. These results demonstrated that the incorporation of NBC slightly improved the thermal properties of the synthesized composites.

“…A menor estabilidade térmica da FB não tratada está associado a maiores concentrações de hemicelulose, ceras e outros componentes de menor massa molar, que possuem temperatura de decomposição menor em relação à celulose. Após o tratamento químico, partes desses componentes são extraídos da fibra, promovendo uma maior estabilidade térmica, verificada pelo aumento da temperatura de início (To) e final (Te) de degradação do estágio III na decomposição da FB e observada através do deslocamento para a direita da temperatura do pico da DTG nas FB tratadas, resultado atribuído a maior concentração de celulose remanescente nas FB tratadas [18] . Para confirmar a remoção dos componentes de menor massa molar na FB, foi realizada a análise por infravermelho e na Figura 3 são apresentados os espectros de infravermelho da FB antes e após o tratamento alcalino.…”

Resumo: Neste trabalho foi avaliada a influência do tratamento alcalino na fibra de bananeira (FB) e seu uso como agente de reforço em compósitos expandidos de poli(etileno-co-acetato de vinila) -EVA. O processo de mistura dos compósitos ocorreu em um misturador de rolos aberto e após conformados e expandidos em uma prensa aquecida com moldes de volumes variáveis. Os compósitos foram avaliados por suas propriedades mecânicas, térmicas e morfológicas. Os resultados indicam que o tratamento alcalino promove a extração de componentes menos estáveis na FB, tais como a lignina, hemicelulose, ceras e óleos de baixo peso molecular. O uso da FB nos compósitos proporciona um decréscimo das propriedades mecânicas de resistência à tração e rasgo em relação ao EVA puro devido a moderadas propriedades de interface polímero-fibra. Nos compósitos expandidos, as propriedades mecânicas decrescem com a diminuição da densidade em função da maior presença de espaços vazios no interior dos compósitos, porém as propriedades mecânicas específicas de resistência ao rasgo apresentaram melhores resultados com 10 pcr de FB em todos os moldes utilizados.

Influence of the Chemical Treatment of Banana Fiber on Poly(ethylene-co-vinyl acetate) Composites with and without a Blowing AgentAbstract: In this work the influence of alkaline treatment on banana fiber (BF) and its use as reinforcement agent in expanded composites of poly(ethylene-co-vinyl acetate) -EVA were assessed. The mixing process for the composite was performed in an open roll mill, with composites being then shaped and expanded in a thermal press using variable volume molds. The composites were evaluated as for their mechanical, thermal and morphological properties. The results indicate that the alkali treatment promotes the extraction of less stable BF components such as lignin, hemicellulose, waxes and low molecular weight oils. The use of BF in the composites imparts reduction in mechanical properties of tensile and tear strength compared to neat EVA, owing to the moderate properties of the polymer-fiber interface. In expanded composites, the mechanical properties decreased with the reduction in density due to a higher amount of void spaces within the composites. However, the specific mechanical properties of tear strength showed improved results with 10 phr BF in all molds.

“…The use of suitable compatibilizers or the chemical treatment of filler and matrix would be some alternatives to minimize the problem of compatibility (Rowell 2005, Wu et al 2000, Nachtigall et al 2007). The mechanical, morphological and thermal properties of different wood flour (sisal, jute, flex, hemp, kneaf, bamboo, oil palm) of various size and concentration have been studied and reviewed in detail (Adhikari et al 2012, Zaini et al 1996, Kalaprasad et al 2004, Chattopadhayay, 2011. Aim of the study was to study the effectiveness of chemically modified bamboo flour through analyzing morphological and mechanical behaviors of the bamboo flour reinforced polypropylene composites.…”

In this paper, the bamboo flour (BF) reinforced polypropylene (PP) composites were studied with special attention to morphology of the composites and the effectiveness of chemically modified fillers to improve their mechanical properties. The composites of polypropylene with neat bamboo flour (BF) and treated bamboo flour (TBF) in different proportions were prepared by melt mixing followed by compression molding. The samples were characterized by Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), tensile testing and water absorption testing. The results show that the alkali treated BF is compatible with polypropylene matrix than the neat one as the effects are reflected in the morphological features of the composites and their tensile mechanical properties.
