“…, biowaste), thereby competing, in this case, with synthetic fibers in terms of biodegradability, cost-effectiveness and environmental and human safety. 11–14 CNFs are the most widely used NC materials in a wide range of applications, both as additives and as building blocks for the design of nanostructured materials. They comprise both amorphous and crystalline cellulose domains, with a high surface-to-volume ratio and a mechanical strength greater than synthetic petroleum-derived fibers (plastic polymers).…”

“…As demonstrated in Equation (1), the crystallinity can be estimated by the analysis of X-ray diffraction patterns.

where A crystal and A amorphous were calculated according to the literature method [ 25 , 26 ], using Gaussian fitting. For cellulose II, A crystal denotes the integral area of the (200) characteristic diffraction peak located at 20.4°, and A amorphous represents the integral area of the predominantly amorphous peak located at 18.0°.…”

To improve the physical strength of regenerated cellulose fibers, cellulose dissolution was analyzed with a conductor-like screening model for real solvents in which 1-allyl-3-methylimidazolium chloride (AMIMCl) worked only as a hydrogen bond acceptor while dissolving the cellulose. This process could be promoted by the addition of urea, glycerol, and choline chloride. The dissolution and regeneration of cellulose was achieved through dry-jet and wet-spinning. The results demonstrated that the addition of hydrogen bond donors and acceptors either on their own or in combination can enhance the tensile strength, but their effects on the crystallinity of the regenerated fibers were quite limited. Compared with the regenerated fibers without any additives, the tensile strength was improved from 54.43 MPa to 139.62 MPa after introducing the choline chloride and glycerol, while related the crystallinity was only changed from 60.06% to 62.97%. By contrast, a more compact structure and fewer pores on the fiber surface were identified in samples with additives along with well-preserved cellulose frameworks. Besides, it should be noted that an optimization in the overall thermal stability was obtained in samples with additives. The significant effect of regenerated cellulose with the addition of glycerol was attributed to the reduction of cellulose damage by slowing down the dissolution and cross-linking in the cellulose viscose. The enhancement of the physical strength of regenerated cellulose fiber can be realized by the appropriate adjustment of the hydrogen bond distribution in the ionic liquid system with additives.

“…Segundo Salas et al (2014), soluções com alta concentração de nanocelulose cristalina dispersas formam um ordenamento helicoidal e, conforme sua caracterização reológica, formam um cristal líquido que assume propriedades de um fluido. A estrutura formada pelos cristais em suspensão pode ser mantida através da evaporação lenta da água, resultando em um filme sólido (AKATAN et al, 2022). Os filtrados pós hidrolise ácida estão apresentados na Figura 5.…”

A busca por novos materiais sustentáveis ocasiona um aumento gradativo de estudos direcionados à utilização de matéria-prima renovável, visando gerar produtos não agressivos ao meio ambiente, mantendo sua qualidade e desempenho. Os frutos do ingá-cipó geram resíduos que são ótimas fontes de biomassa lignocelulósica. Nesse sentido, o objetivo deste trabalho foi obter micro e nanocelulose cristalina a partir da biomassa lignocelulosica da casca do fruto do ingá-cipó via tratamento químico, assim como realizar sua caracterização físico-química e morfológica. As cascas foram submetidas a uma extração sequencial de hemicelulose e lignina, seguindo da síntese de micro e nanocelulose por hidrólise ácida. O material obtido foi caracterização através de infravermelho com transformada de Fourier (FTIR) e microscopia eletrônica de transmissão (MET). Através das análises de FTIR foi possível constatar a presença dos grupos funcionais típicos de celulose. As imagens provenientes do MET, auxiliaram a visualização de micro e nanocelulose cristalina, que poderão ser utilizadas na geração de novos materiais com melhor valor agregado.
