“…17,18 Over the last two decades, the research of polymerclay nanocomposites (PCN) have attracted several researchers to focus on PCN materials as a very little addition of nanolayered organo montmorillonite (MMT) ($5 wt.%) clay caused two fold increase in modulus, 25% increase of strength, 50 C increase of heat deflection temperature (HDT), and other thermomechanical properties. 19,20 Several papers on nanoclays infused in thermoset, 21 thermoplastic, 22 elastomers, 23 blends, and copolymers 24 were also available.…”

The objective of this work is to infuse nanoclay particles into the banana fiber and study the morphological and structural characteristics. Nanoclays were infused into the fibers by shear induced force with the aid of alkaline (NaOH) chemical treatment. About 6 wt.% of nanoclays were infused into the banana fibers by this method. The short banana fiber reinforced epoxy composites were prepared by resin casting method in which the critical length (l c ) and critical volume fraction (V fc ) of the fibers were determined. The nanoclay infused fibers were compared with untreated and alkaline treated fibers. The result suggests a positive effect on tensile, interfacial, and thermal properties of fibers due to nanoclay infusion. The tensile, shear, and dynamic mechanical analysis (DMA) of composites were studied, and the result shows superior improvement of these properties in nanoclay infused fiber composites.

“…22,27 De maneira inversa o resíduo de borracha (Figura 4b) é um material com superfície plana e uniforme, onde há dificuldade de adesão de materiais a sua superfície, o que pode ser facilitado quando se realizam microfraturas no material, que podem ser observadas nas micrografias do resíduo de borrachas. 25,28,29 As micrografias dos polímeros de base podem ser observadas na Figura 5, estes foram utilizados em sua forma comercial, ou seja, em pellets, tanto o EVA HM2528 (Figura 5a), quanto o Capro-PU (Figura 5b), apresentaram uma superfície lisa, demonstrando uma organização superficial da estrutura polimérica do material. Capro-PU Para os materiais processados em extrusora, assim como no TGA, realizaram-se os ensaios de MEV para as blendas 1 e 4, e as respectivas micrografias com aproximações de 1000 vezes e 4000 vezes, podem ser observadas na Figura 6.…”

Recycling Footwear Industry Waste and Evaluation the Deterioration in SoilAbstract: The production of footwear generates various residues, such as cotton fabric flaps and rubber chips, which are materials that have characteristics that make it difficult to recycle. Thus, the objective of this study is the mechanical recycling of these residues, obtaining blends of these residues with Capro-PU and EVA. They are processed mechanically by comminution, extrusion and pelletizing, obtaining chemically analyzed materials and subsequently submitted to the injection and lamination processes in order to observe the characteristics in the form of industrialized products. The materials were characterized by Scanning Electron Microscopy, thermogravimetric analysis and CO 2 release rate evaluation. The recycled materials were subjected to the lamination and injection processes where they were evaluated according to characteristic tests for the production of assembly insoles. By the TGA, it was possible to verify that the blends had a greater thermal stability when compared to the pure consumables. Regarding the mechanical tests, all blends were within the limits established by the PFI and showed values of CO 2 release rate higher than the values of the test only with the fabric, since this is a biodegradable material. Thus, it is observed that the present study is a breakthrough for materials processing technology, creating new products with suitable characteristics for manufacturing processes and presenting microbiological degradation capacity, when discarded in soil.Keywords: Recycling; Mechanical processing; Footwear; Solid waste; Microbiological degradation. ResumoA produção de calçados geram diversos resíduos, tais como retalhos de tecido de algodão e aparas de borracha, que são materiais que apresentam características que dificultam sua reciclagem. Assim, o objetivo deste estudo é a reciclagem mecânica destes resíduos, obtendo blendas destes resíduos com Capro-PU e EVA. Sendo processados mecanicamente por cominuição, extrusão e peletização, obtendo-se materiais analisados quimicamente e posteriormente submetidos aos processos de injeção e laminação a fim de observar as características na forma de produtos industrializados. Os materiais foram caracterizados por ensaios de Microscopia Eletrônica de Varredura, análise termogravimétrica e avaliação da taxa de liberação de CO 2. Os materiais reciclados foram submetidos aos processos de laminação e injeção onde foram avaliados de acordo com ensaios característicos para a produção de palmilhas de montagem. Pelo TGA foi possível verificar que as blendas ficaram com uma maior estabilidade térmica quando comparado aos insumos puros. Em relação aos ensaios mecânicos, todas as blendas ficaram dentro dos limites estabelecidos pelo PFI e apresentaram valores de taxa de liberação de CO 2 superiores aos valores do ensaio somente com o tecido, visto que este é um material biodegradável. Desta forma, observa-se que o presente estudo é um avanço para a tecnologia de processamento de mater...
