Polyhydroxyalkanoates (PHAs) comprise a family of biodegradable aliphatic polyesters with enhanced sustainable profile and high water vapor barrier. As environmentally friendly materials, nanostructured cellulose-based films, also called nanopapers, such as films made of cellulose nanofibrils (CNFs) and lignocellulose nanofibrils (LCNFs), are also of growing interest due to their high mechanical strength...
There is a recent interest in producing cellulose nanofibers with different surface properties from unbleached cellulose pulps for economic and environmental reasons. In the current study we investigated the use of xylanase pretreatment on two types of unbleached rice straw pulps, namely, soda and neutral sulfite, and their fibrillation to nanofibers using ultrafine grinding. The effect of xylanase...
This study aims to evaluate the suitability of using nanopaper as an insulating material since it has outstanding mechanical and thermal properties. Nanopaper consisting of nanofibrillated cellulose was prepared. Properties of ordinary insulating paper were taken as a reference. DC volume resistivity results show that nanopaper can obtain a relatively high value of 2.55 × 1012 Ω m, which will be more...
Cellulose nanofibrils (CNF), once filtered and dried, have the particularity to form a highly cohesive network, nanopaper. One of the drawbacks of all CNF nanopapers is their relative brittleness and low tear resistance, measured as the force needed for crack propagation after introducing a notch. In this work, hybrid nanopapers with drastically improved tear and crumpling resistance were produced...
