Resumo
Atualmente a geração de fibras em escala micrométrica e nanométrica tem ganhado destaque devido a inúmeras aplicações destes materiais principalmente na área biomédica, por apresentarem alta capacidade mimética, como por exemplo, os scaffolds, estruturas utilizadas na engenharia de tecidos. Dentre as técnicas utilizadas para a geração destas fibras temos: fiação, eletrofiação, impressão 3D e rotofiação. A rotofiação é uma técnica simples, de baixo custo e que apresenta maior taxa de produção quando comparada às demais. Sendo assim, este trabalho tem por objetivo a construção de um protótipo, além de explorar os principais aspectos tais como: conceito, tipos de configurações, parâmetros que influenciam a geração das fibras e aplicações. A montagem do protótipo será baseada em conceitos e equipamentos existentes no mercado. O rotofiador apresenta a seguinte configuração: copo oco (deposição da solução polimérica), motor e sistema coletor de fibras. Através deste trabalho espera-se obter um equipamento versátil e de fácil manuseio, permitindo a obtenção de micro ou nanofibras a partir de biopolímero. Cabe ressaltar que não existe este equipamento para compra no mercado e pesquisa realizada para sua construção com fornecedor verificou-se que o preço fica em torno de 15 mil reais. Com isso, através deste estudo verificou-se que é possível a construção de um rotofiador de baixo custo, podendo ficar em torno de 2 mil reais.
Currently, the generation of fibers in micrometric and nanometric scales has gained prominence due to numerous applications of these materials mainly in the biomedical area, due to their high mimetic capacity, such as scaffolds, structures used in tissue engineering. Among the techniques used for the generation of these fibers we have: spinning, electrospinning, 3D printing and rotospinning. Rotation is a simple, low-cost technique that has a higher production rate when compared to the others. Therefore, this work aims to build a prototype, in addition to exploring the main aspects such as: concept, types of configurations, parameters that influence the generation of fibers and applications. The assembly of the prototype will be based on existing concepts and equipment on the market. The roto spinner has the following configuration: hollow cup (deposition of the polymeric solution), motor and fiber collection system. Through this work, it is expected to obtain versatile and easy-tohandle equipment, allowing the production of micro or nanofibers from biopolymers. It is worth mentioning that this equipment does not exist for purchase in the market and research carried out for its construction with a supplier it was found that the price is around 15 thousand reais. With this, through this study it was verified that it is possible to build a low cost rotofiador, being able to be around 2 thousand reais.
