Eco-friendly bio-nanocomposites: incorporation of nano-cellulose from pineapple leaf waste into tissue paper
A lot of attention has been paid to cellulose nanocrystals (CNCs) due to their wide availability with a great potential to replace synthetic materials. The formation of CNCs from agricultural waste has numerous positive economic and environmental consequences. Cellulose nanocrystals were synthesized from pineapple leaf by acid hydrolysis and characterized by FT-IR, XRD, SEM, TEM, etc. Different concentrations of cellulose nanocrystals (1%, 3%, and 5% w/w) reinforced gelatin-based bio-nano composite was coated on tissue paper. The optimized fibrogenic solution was infused with three different plant leaf extracts (Banana leaf extract, Mantharai leaf extract, and Lotus leaf extract) used as an antimicrobial agent for hygienic tissue paper. Thickness, grammage, and bulk density analysis show the efficiency of the coating formation. The coated tissue paper shows increased mechanical properties and air permeability but significantly reduced water vapour permeability. Antimicrobial efficacy showed improved activity against Gram-positive bacteria Staphylococcus aureus (ATCC-2913), Gram-negative bacteria Escherichia coli (ATCC-27853), and fungi Candida glabrata (NCYC 388). These results reveal the potential of cellulose materials to serve as accessible platforms for anti-infective or self-sterilizing materials against both bacteria and fungi.
期刊介绍：
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
