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

Abstract

Abstract:The development of (nano)materials based on the renewable cellulose is a challenge. The present article provides a brief overview of the recent research efforts carried out at the CICECO Laboratory of the University of Aveiro on the development of novel composites based on nanofibrillated plant and bacterial cellulose embedded in natural and synthetic polymeric matrices such as poly(lactic acid), chitosan, starch, and pullulan. These materials have high potential for applications in packaging, paper coating, organic electronics, and biomedical products and devices.

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

“…Table 2 lists such studies based on the type of nanocellulose.

A potential advantage of this kind of system is that absorption of water by the underlying paper can rapidly immobilize the coating.…”

“…Also, there has been much interest and research related to cellulose fiber usage in composite materials for packaging (Johansson et al 2012;Faruk et al 2014). Research related to the use of nanocellulose in packaging applications also has been reviewed (Turbak et al 1983;Dufresne 2008Azeredo 2009;Eichhorn et al 2009;Oksman et al 2009;Habibi et al 2010;Siqueira et al 2010;Siro and Plackett 2010;Moon et al 2011;Olsson et al 2011;Petersen and Gatenholm 2011;Faruck et al 2012;Huber et al 2012;Khalil et al 2012Khalil et al , 2014Lavoine et al 2012;Freire et al 2013;Lopacka 2013;Paunonen 2013a,b;Sandquist 2013;Cowie et al 2014;Khan et al 2014a;Tammelin and Vartiainen 2014;Mihindukulasuriya and Lim 2014;Azizi Samir et al 2015;Hannon et al 2015;Li et al 2015a;Simao et al 2015;Gomez et al 2016;Khalil et al 2016). In particular, Lindström and Aulin (2014) reviewed research progress up to 2014, emphasizing some of the key unmet issues that are likely to continue to slow down progress in production-scale implementation of nanocellulose in packaging.…”

Bio‐Based Materials

“…Production yields are still relatively low (around 10-40 g L -1 ) depending on the bacteria and substrate used, keeping its price high [15]. However, BC is already being used commercially in diet foods, filtration membranes, paper additives and biomedical products and devices [16]. …”

Enhanced stability of PVA electrospun fibers in water by adding cellulose nanocrystals

“…One of the most common reinforcing agent is nanocellulose (NC) in hydrophilic and hydrophobic polymer matrices (Siro and Plackett 2010;Laka et al 2011;Freire et al 2013). NCs are hydrophilic and have high Young's modulus of 80 to 143 GPa (Garcia de Rodriguez et al 2006;Habibi et al 2010).…”
