“…This fibrillation effect tends to positively influence dispersion properties of CNPs when they are filled in starch biofilm matrix. 38 In addition, high aspect ratio (length to diameter) and surface area of alkaline treated CNPs is expected to improve particle matrix interface adhesion and load transfer characteristics.Figure 1.SEM image of fibrillated CNPs, (a) untreated, (b) alkaline treated, (c) grinded untreated and (d) grinded alkaline treated.…”
In this study, structural, thermal, mechanical and water uptake properties on the influence of alkaline treated cellulose nanoparticles (CNPs) filled starch-based bioplastic film is examined. Starch-based bioplastic films filled with alkaline treated CNPs at various concentration (0 to 5 wt%) were prepared by solution casting method. Thermal properties of film series are examined by Differential Scanning Calorimetry (DSC) and Thermogravimetry analysis (TGA) method. Alkaline treated CNPs addition induces crystallization to the bioplastic film. Degradation onset temperature ( Don), 10% mass loss ( T10) and 50% mass loss ( T50) values show the positive effect of CNPs addition into the biopolymer matrix with improved thermal stability. Tensile result shows that about 2.5 times increased is observed in 2 wt% CNPs filled bioplastic films. Water uptake result shows that the alkaline treated CNPs starch-based bioplastic film limit the biopolymer dissolution time and extended the breaking down of the bioplastic film. Leading to about 2.5 times reduced equilibrium water mass uptake is observed in 3 wt% CNPs filled bioplastic film when compared with unfilled bioplastic film.

The utilization of living organisms for the creation of inorganic nanoscale particles is a potential new development in the realm of biotechnology. An essential milestone in the realm of nanotechnology is the process of creating dependable and environmentally acceptable metallic nanoparticles. Due to its increasing popularity and ease, use of ambient biological resources is quickly becoming more significant in this field of study. The phrase “green nanotechnology” has gained a lot of attention and refers to a variety of procedures that eliminate or do away with hazardous compounds to repair the environment. Green nanomaterials can be used in a variety of biotechnological sectors such as medicine and biology, as well as in the food and textile industries, wastewater treatment and agriculture field. The construction of an updated level of knowledge with utilization and a study of the ambient biological systems that might support and revolutionize the creation of nanoparticles (NPs) are presented in this article.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
