“…With increasing content of the alkyd, the amount of white spots decreased (Figure 6b,c). At the same time, incorporation of plasticizers has led to larger amorphous phases, where the segmental chain movement increases, leading to higher flexibility of the PVC chains [9,16,19,33]. Figure 6d,e illustrates that PVC-H/DiNP6 and PVC-L/DOP6 blended with 10 phr of the alkyd showed similar morphology to PVC-H/DOP6 blended with 10 phr of the alkyd (Figure 6b).…”

Flexible poly(vinyl chloride) (PVC) was fabricated using a palm oil-based alkyd as a co-plasticizer to di-octyl phthalate (DOP) and di-isononyl phthalate (DiNP). The effects of the incorporation of the palm oil-based alkyd on morphological, thermal and mechanical properties of PVC compounds were studied. Results showed the incorporation of the alkyd enhanced the mechanical and thermal properties of the PVC compounds. Fourier transform infrared spectroscopy (FTIR) results showed that the polar -OH and -C=O groups of alkyd have good interaction with the -C-Cl group in PVC via polar interaction. The morphological results showed good incorporation of the plasticizers with PVC. Improved tensile strength, elastic modulus, and elongation at break were observed with increasing amount of the alkyd, presumably due to chain entanglement of the alkyd with the PVC molecules. Thermogravimetric analysis results confirmed that the alkyd has improved the thermostability of the PVC compounds.

“…Hoje já são utilizadas fibras de sisal, bambu, bagaço de cana-de-açúcar, curauá, madeira, fibra de bananeira, entre outras. O emprego de fibras naturais como reforço em matriz polimérica, tanto utilizando materiais termofixos como as resinas de poliésteres, epóxis e fenólicas como termoplásticos, principalmente o polipropileno (PP), polietileno (PE) [6,7] e poucos estudos utilizam o poli (cloreto de vinila) (PVC) flexível [8][9][10][11][12][13][14] e rígido [15,16]. Zainudin et al [15] avaliaram a degradação térmica de compósitos de PVC rígido e fibra de bananeira, e foi observado que a adição das fibras não altera o processo de degradação térmica do PVC.…”

“…Se não ocorrer o tratamento da fibra ou a adição de agente compatibilizante, a fraca adesão entre as fases resulta em perda nas propriedades mecânicas [13]. Com objetivo de melhorar a compatibilização entre a fibra e a matriz polimérica, métodos como, modificação da superfície da fibra a partir de tratamentos químicos ou adição de agente compatibilizantes são utilizados [4,[17][18][19].…”

“…Após o tratamento, os autores observaram uma diminuição na absorção de água e um aumento da resistência ao impacto e no módulo de Young. Djidjelli e colaboradores [13] estudaram compósitos de PVC flexível/fibras de sisal tratadas com anidrido maleico e observaram que o tratamento melhorou a compatibilidade do PVC com fibra, diminuindo a absorção de água e melhorando as propriedades mecânicas.…”

RESUMOO interesse de compósitos de fibras naturais com polímeros termoplásticos vem crescendo a cada ano. As fibras naturais apresentam vantagens como baixa massa específica, baixa abrasividade, baixo custo, são biodegradáveis e autossustentáveis, pois são de origem natural e de fonte renovável. Dentre as resinas termoplásticas viáveis para o emprego de fibras de bananeira destaca-se a resina de poli (cloreto de vinila) -PVC por sua versatilidade em relação a sua formulação, pois há a necessidade da incorporação de aditivos durante o seu processamento, tornando-a adaptável a múltiplas aplicações. O objetivo do presente trabalho foi estudar a influência do tipo de tratamento das fibras de bananeira (FB) nas propriedades do PVC rígido (PVCr). Propriedades mecânicas, estabilidade térmica e absorção de água dos compósitos PVC/FB foram avaliados em relação ao efeito dos tratamentos alcalino, com anidrido maleico e acetilação das fibras de bananeiras. Os compósitos foram obtidos em misturador aberto de dois rolos seguido de injeção dos corpos de provas. Os resultados indicam que o tratamento com anidrido maleico e a acetilação apresentam melhor resistência ao impacto e menor absorção de água do que o tratamento alcalino. As propriedades térmicas não apresentaram alterações significativas com a adição de fibras de bananeiras tratadas e não tratadas. Palavras-chave: poli (cloreto de vinila); fibras de bananeira; tratamento superficial. ABSTRACTThe interest in natural fiber composites with thermoplastic polymers is growing every year. Natural fibers have advantages such as low density, low abrasion, low cost, are biodegradable and self-sustainable, since they are natural and renewable source. Among the thermoplastic resins viable for employment fiber banana stands out poly (vinyl chloride) -PVC for its versatility compared to its formulation, because there is the need to incorporate additives during processing, making adaptable to multiple applications. The objective of this work was to study the influence of type of banana fibers (FB) treatment in the properties of rigid poly (vinyl chloride) (PVC). Mechanical properties, thermal stability and water absorption of composite PVC/FB were evalueted for the effect of alkaline treatments, with maleic anhydride and acetylation of banana fibers. The composites were obtained in two-roll open mixer followed by injection of test samples. The results indicate that treatment with maleic anhydride and acetylation exhibit better impact resistance and lower water absorption than the alkaline treatment. The thermal properties did not change significantly with the addition of banana fibers treated and untreated.

“…low cost, low density, high toughness, acceptable specific strength, biodegradability and enhanced energy recovery. The natural fibre uses in plastic matrix have a lot of benefits, for instance low cost, increase of stiffness of thermoplastics, increase of heat deflection temperature, and improvement of surface exterior [1]. The sugarcane bagasse (SCB) is a residue extensively generated in high extent in the agro-industry.…”
