The prepared nanocomposite, TEMPO-CNF/TiO 2 , was characterized by using FT-IR, XRD, TGA, SEM, and EDX analysis. The results proved that homogenous spherical TiO 2 nanoparticles were formed with the particles of TEMPO-CNF. TEMPO-CNF/TiO 2 nanocomposite was examined as an adsorbent for ...
Cellulose nanofiber (CNF) isolation from different resources influences the characteristics of the CNF. There are two methods to isolate CNFs, chemical and physical methods. This paper deals with a 2,2,6,6-tetramethylpiperidine- 1-oxylradical (TEMPO-oxidation) chemical method and aqueous counter ...
In this article, TEMPO-oxidized cellulose nanofiber (TEMPO-CNF) prepared from bagasse was described and utilized as a sustainable material for the preparat... ZA Al-Ahmed,AA Hassan,ESSE El-Khouly - 《Polymer Bulletin》 被引量: 0发表: 2020年 Characteristics of TEMPO-Oxidized Cellulose Nanofibers...
However, when a dual surface-modified TEMPO-CNF sample containing phenyl amides and PAG-ammonium/carboxylate salt structures at amidation and amine/carboxylate salt formation degrees of 80% and 6% of the carboxy groups in the TEMPO-CNFs, respectively, the thermal dimensional stability of the neat ...
We hypothesized that the addition of TOCNF would reduce steric strains between CS molecules and improve CS-to-GP interaction for faster gelation rate, resulting in a more rigid structure, which would serve as a stable platform for cell attachment and growth, consequently improving biocompatibility. ...
“random forest” machine learning algorithm for regression analysis. As a result, the design of tailor-made TOCNF-based films can be achieved with reduced experimental expenditure. We envision this approach to be useful in facilitating adoption of TOCNF for the design of emerging flexible ...
Conversely, high-aspect ratio cellulose nanofibrils (CNFs) exhibit reinforcing effects that have been attributed to the presence of entangled CNF networks capable of bridging crazes formed in composites during tensile testing [13]. The high-aspect ratio of CNFs facilitates fibril interlocking across ...
All-cellulose composites (ACCs) are manufactured using only cellulose as a raw material. Biobased materials are more sustainable alternatives to the petroleum-based composites that are used in many technical and life-science applications. In this study,
In this study, adsorption of lead ions has been studied by nanocomposites which prepared through acrylic acid grafting and amino-functionalized magnetized (FM-NPs) TEMPO-oxidized cellulose nanofiber (TEMPO-CNF). The amino-functionalized magnetite was acting as a crosslinked. The crystallinity of TEMPO...
In this sense, two different 3D structures were synthetized: CNF-calcium alginate beads and CNF-aerogels. After the synthesis and characterization of 3D structures, batch sorption studies were performed by using these sorbents to study their ability for metal removal. Equilibrium data fitted very ...
