Blends of thermoplastic cornstarch (TPS) and chitosan (TPC) were obtained by melt extrusion. The effect TPC incorporation in TPS matrix polymer interaction on morphology thermal mechanical properties investigated. Possible interactions between the starch molecules assessed XRD FTIR techniques. Scanning Electron Microscopy (SEM) analyses showed a homogeneous fracture surface without presence granules or aggregates. Although caused decrease both tensile strength stiffness, films with better...
There is growing interest in cellulose nanofibres from renewable sources for several industrial applications. However, there a lack of information about one the most abundant pulps: bleached Eucalyptus kraft pulp. The objective present work was to obtain micro/nanofibres by three different processes, namely: refining, sonication and acid hydrolysis refining limited low efficiency isolated nanofibrils, while more effective this purpose. latter process occurred at expense considerable damage...
Since the discovery of laser-induced graphene (LIG), significant advances have been made to obtain green LIG (gLIG) from abundant, eco-friendly, natural, and organic renewable bio-based carbon sources. Recently, some sustainable cost-effective electronic devices designed with gLIG, resulting in diverse solutions environmental impact caused by waste (e-waste). However, there are still several challenges that must be addressed regarding widespread market implementation gLIG-based products,...
The application of green process engineering strategies to obtain high-value, eco-friendly, and biodegradable materials from residual lignocellulosic biomass can contribute the sustainability future biorefineries. Here, we investigated potential sugarcane bagasse straw as feedstocks nanocellulose, using enzymatic hydrolysis route a platform. fibers were submitted purification followed by with commercial enzyme cocktail. cellulose nanomaterials obtained both (sugarcane straw) presented high...
The main objective of this study was to evaluate the effect addition different concentrations CMC (0, 20, 40, 60, 80 and 100 %) on mechanical water vapor barrier properties in corn starch films produced by casting. 40 % sufficient significantly increase its (tensile strength, elongation at break elastic modulus), films, thus improving functionality as a packaging material for food. incorporation led small reduction thermal stability films. low content dispersed well matrix, ensuring...
Nanocellulosic materials, either as cellulose nanofibrils (CNF) or nanocrystals (CNC), have a wide range of potential applications in different industrial sectors, due to their renewable nature and remarkable properties. Here, sustainable environmentally friendly method obtain nanocellulose was evaluated using hydrolysis with citric acid, an organic acid that can be obtained biorefinery product. This approach resulted single-step extraction nanocellulose, carboxyl functionalization the...
MWCNT and CNF are interesting NPs that possess great potential for applications in various fields such as water treatment, reinforcement materials medical devices. However, the rapid dissemination of can impact environment human health. Thus, aim this study was to evaluate cotton toxicological effects on freshwater green microalgae Chlorella vulgaris. Exposure led reductions algal growth cell viability. NP exposure induced reactive oxygen species (ROS) production a decreased intracellular...
This paper reports the antibacterial effect and physico-chemical characterization of films containing silver nanoparticles for use as food packaging. Two masterbatches (named PEN PEC) con- taining embedded in distinct carriers (silica titanium dioxide) were mixed with low-density polyethylene (LDPE) different compositions extruded to produce plain films. These characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Differential Calorimetry (DSC), Thermogravimetric...
The isolation of cellulose nanocrystals (CNCs) by organic acid hydrolysis can contribute to reducing the extensive use mineral acids, but aspects related performance, cost effectiveness, and sustainability still need be addressed. Here, techno-economic analysis (TEA) life cycle assessment (LCA) were performed evaluate production CNCs using and/or inorganic hydrolysis, in context a sugar cane biorefinery. extracted from bagasse sulfuric (S-CNC), citric (Cit-CNC), their combination...
