There has been an increasing interest in research on using bio-renewable polymers as a replacement to traditional synthetic based petroleum resources for adhesive applications. Cellulose, which is the most abundant biopolymer finds application reinforcing agent conventional adhesives. However, natural polymer cellulose suffers from few drawbacks like poor water resistance, low mechanical streng...
C is the second most important natural polymer in the nature after cellulose. The main sources of the chitin compounds are shrimp and crabs.Our objective is to discuss the state of the art on extraction of nano chitin whiskers and Chitin based nanocomposites using different type of polymer matrixes. This review manly focuses on the preparation, characterization, properties, morphologies and che...
The mechanical properties of rodlike cellulose nanocrystals (CNCs) suggest great potential as bioderived reinforcement in (nano)composites. Poly(vinyl alcohol) (PVOH) is a useful industrial material and very compatible with CNC chemistry. High performance CNC/PVOH composite fibers were produced coaxial coagulation spinning, followed by hot-drawing. We showed that CNCs increase the alignment and...
This study aimed to produce bacterial cellulose from paper waste sludge (PWS) as a method of utilizing the source remaining pulp in material. Initially, PWS was hydrolyzed by sulfuric acid create an enriched-reducing sugar hydrolysate. One-factor experiments were conducted with fixed amount (5 g) investigate influence hydrolysis conditions, including water, addition, temperature, and retention ...
The data presented in this article is related to the research article entitled "Paclitaxel loaded magnetic nanocomposites with folate modified chitosan/carboxymethyl surface; a vehicle for imaging and targeted drug delivery" (S. Bano, M. Afzal, M.M. Waraich, K. Alamgir, S. Nazir, 2016) [1]. It contains the absorbance spectra, band gap energies of pure nickel-ferrite nano cores (NFs), and calibr...
As a key component of lithium-ion batteries (LIBs), separator plays crucial role in the performance and safety LIBs. In this paper, cellulose-based porous membrane modified by nano CaCO3 is prepared conveniently electrospinning. The exhibits rich fibrous networks uniform distribution nanoparticles. Strengthened CaCO3, tensile strength cellulose elevates from 4.7 ± 0.4 MPa to 7.7 0.7 MPa. Beside...
Pyrocatechol is immobilized on cellulose via NHCH(2)CH(2)NHSO(2)C(6)H(4)NN linker and the resulting macromolecular chelator characterized by IR, TGA, CPMAS (13)C NMR and elemental analyses. It has been used for enrichment of Cu(II), Zn(II), Fe(III), Ni(II), Co(II), Cd(II) and Pb(II) prior to their determination by flame atomic absorption spectrometry (FAAS). The pH ranges for quantitative sorpt...
In this work, four different nanocellulose (NCs) aqueous suspensions (two Cellulose Nano-Fibrils-CNF and a pair of Nano-Crystals-CNC) were selected for the evaluation key aspects that potentially affect final performance mortars. The main objective was development appropriate mixing protocols will allow incorporation cellulose nanoadditives into cementitious blends. Inclusion two NC species mor...
