Biodegradation evaluation of bacterial cellulose, vegetable cellulose and poly (3-hydroxybutyrate) in soil
(Assoc Brasil Polimeros, 2015-03-01)
In recent years, the inappropriate disposal of polymeric materials has increased due to industrial development and increase of population consumption. This problem may be minimized by using biodegradable polymers, such as ...
Kinetic study of the thermal decomposition of cellulose nanocrystals with different polymorphs, cellulose I and II, extracted from different sources and using different types of acids
(Elsevier B.V., 2015-12-15)
Cellulose nanocrystals (CNs) were extracted from different sources by acid hydrolysis using H2SO4 and HCI. The thermal decomposition of resulting CNs was studied by thermogravimetric analysis (TGA). The kinetic parameters ...
Cellulosic Films Obtained from the Treatment of Sugarcane Bagasse Fibers with N-methylmorpholine-N-oxide (NMMO)
(HUMANA PRESS INC, 2009)
Ethanol/water organosolv pulping was used to obtain sugarcane bagasse pulp that was bleached with sodium chlorite. This bleached pulp was used to obtain cellulosic films that were further evaluated by Fourier transform ...
Antifungal cellulose by capsaicin surface grafting
(Springer, 2014-05)
Cellulose is one of the most abundant materials in nature. Besides its biological function, cellulose can be extracted from the cell wall and used in several industrial applications. Thus, it can be used in papers, ...
Upcycling Microbial Cellulose Scraps into Nanowhiskers with Engineered Performance as Fillers in All-Cellulose Composites
(2020-10-14)
Cellulose is everywhere and renovates in nature continuously and rapidly, while petroleum does not. Unlike the latter, cellulose biodegrades and may represent a carbon sink. Inspired by the multiscale architecture of ...
A New Approach for Conversion of Eucalyptus Lignocellulosic Biomass into Cellulose Nanostructures: A Method that Can Be Applied in Industry
(2019-01-01)
This study aimed to explore the use of eucalyptus sawdust for the extraction of nanocellulose. This residue was purified with a three-steps pretreatment and ball milled for the isolation of nanocellulose. The method proposed ...
Synthesis and characterization of cellulose acetate from cellophane industry residues. Application as acetaminophen controlled-release membranes
(2021-01-01)
Cellophane film production generates cellulosic residues from scraps, edges, and low-quality films. In this work, cellophane was used as a raw material to produce cellulose acetate (CA). CA was produced through the homogeneous ...
The Future of Bacterial Cellulose and Other Microbial Polysaccharides
(Tech Science Press, 2013-01-01)
Biobased polymers have been gaining the attention of society and industry because of concerns about the depletion of fossil fuels and growing environmental problems. Cellulose fibers are one of the most promising biopolymers ...
Mechanical, thermal, and barrier properties of methylcellulose/cellulose nanocrystals nanocomposites
(2014)
In this work, the effects of incorporating cellulose nanocrystals from soy hulls (WSH30) on the mechanical, thermal, and barrier properties of methylcellulose (MC) nanocomposites were evaluated. MC/WSH30 nanocomposite films ...
Development of a composite material between bacterial cellulose and E crassipes, for the treatment of water contaminated by chromium (VI)
In recent years, chromium water pollution has become a serious problem for aquatic environments as rivers and wetlands, and for human health. Many researchers are working on finding economic and efficient ways to solve ...
