Mechanical, moisture absorption, and biodegradation behaviours of bacterial cellulose fibre-reinforced starch biocomposites

Propriedades Físicas, Químicas e de Barreira em Filme Formados por Blenda de Celulose Bacteriana e Fécula de Batata

“…Adição de Aloe vera no meio de cultivo durante a biossíntese da celulose bacteriana foi desenvolvido por Saibuatong e Phisalaphong [10] , promovendo reforço no biopolímero, com aumento significativo nas propriedades mecânicas de força, cristalinidade, capacidade de absorção de água e permeabilidade ao vapor de água. Produção de biocompósitos de nanofibrilas de celulose bacteriana e amido realizado por Wan et al [11] observaram eficiência nas propriedades de tensão, resistência a umidade e ao ataque de microrganismos. Celulose bacteriana como reforço em matriz de amido de milho termoplástico foi desenvolvido por Martins et al [12] , e esta combinação exibiu melhores propriedades mecânicas quando comparadas com compósitos de celulose vegetal.…”

Nanocellulose in Thin Films, Coatings, and Plies for Packaging Applications: A Review

“…For instance, the following authors reported improvements in various barrier and strength properties of the thin films achieved through such treatments (Wan et al 2009;Lee et al 2012; Aulin and Ström 2013; Barud et al 2013). Nakagaito and Yano (2004 reported similar work in which fibrillated kraft pulp impregnated with phenolic resin was compressed under very high pressure to make high-strength nanocomposites.…”

“…The nanocellulose in those products made it possible to maintain a stable mesoporous structure, and the films showed promise for use in air filtration.

“…Secondly, the tiny dimensions of nanocellulose imply a high exposure to its surroundings. The issue of biodegradation has been emphasized in studies in which nanocellulose was used in composite structures with other natural film-forming materials (Lu et al 2008;Ma et al 2008;Cheng et al 2009;Wan et al 2009; Azeredo et al 2010;Bras et al 2010;Khan et al 2010Khan et al , 2012Khan et al , 2014bSiro and Plackett 2010;da Silva et al 2012;Hassan et al 2012;Johnsy and Siddaramaiah 2012;Tang et al 2012; Baheti and Militky 2013; ChingaCarrasco et al 2013;Ollier et al 2013; Bhardwaj et al 2014;Dehnad et al 2014a;Fortunati et al 2014;Ghaderi et al 2014;Khalil et al 2014;Kumar et al 2014;Marais et al 2014;Reddy and Rhim 2014;Song et al 2014;Yang et al 2014; Azizi Samir et al 2015; Feng et al 2015a;Figueiredo et al 2015;Honorato et al 2015;Lavoine et al 2015;Li et al 2015a;Lu et al 2015; Youssef et al REVIEW ARTICLE bioresources.com .

Novel cellulose-based composites based on nanofibrillated plant and bacterial cellulose: recent advances at the University of Aveiro – a review

“…BC has a high degree of poly merization and crystallinity, extremely high water holding capacity, high tensile strength, and high surface area (George et al 2005a,b ). BC is well suited as a reinforcing element in nanocomposites in several polymeric matrices, namely, cellulose acetate butyrate (Gindl and Keckes 2004 ), acrylic thermosetting resins Ifuku et al 2007 ), phenolic resins , poly(ethylene oxide) (Brown and Laborie 2008 ), plasticized starch (Wan et al 2009 ), PLA (Kim et al 2009 ), and epoxidized soybean oil matrix (Retegi et al 2012 ), just to mention a few examples.…”
