A new kind of pH and temperature responsive poly(acrylamide‐ co ‐itaconic acid) hydrogel was prepared by free radical polymerization using ammonium persulfate as initiator different comonomer ratios. The hydrogels were characterized in terms chemical composition, swelling‐deswelling behavior, morphology, crystallographic drug release properties. All the showed high swelling ability aqueous solutions, maximum being at 7. Swelling decreased on either side 7 (i.e., both acidic alkaline region)...

A novel adsorbent made of freshly obtained calcium oxide nanoparticles and ferric hydroxide dispersed in chitosan matrix (CHI-FCA) was prepared. Batch adsorption study performed to analyze the effect initial concentration, contact time, pH, dose on fluoride sorption CHI-FCA. It observed that maximum achieved at pH 7.10 an optimum equilibrium time 180 min with 8 g/L. Moreover, a synergistic for remediation from aqueous medium. FTIR, XRD, DLS, TGA, DTA, ESEM EDX analysis were investigation...
Hydrogels responsive to pH change based on poly(acrylamide-co-2-acrylamido-2-methylpropane sulfonic acid) are synthesized. The hydrogels characterized in terms of FTIR spectroscopy, swelling–deswelling behavior, morphological analysis and dye removal properties. swelling the hydrogel is strongly dependent copolymer composition, ionic strength medium. efficiency (DRE) also depends strength. Pseudo-second-order kinetics Langmuir isotherms model, respectively, best-fit models for present gel....
Closed-shell phenalenyl (PLY) systems are increasingly becoming more attractive as building blocks for developing promising catalysts and electroactive cathode materials, they have tremendous potential to accept electrons participate in redox reactions. Herein, we report a PLY-based dinuclear [FeIII2(hmbh-PLY)3] complex, 1, its utility material H2O2 fuel cell. Complex 1 was synthesized from new Schiff base ligand, (E)-9-(2-(2-hydroxy-3-methoxybenzylidene)hydrazineyl)-1H-phenalen-1-one,...
Three different methods have been developed to crosslink the poly(acrylic acid-2-hydroxyethyl methacrylate) form hydrogels having tunable swelling, rheological and morphological properties with applicability in dye heavy metal removal.
Pore structure plays a great role in determining the physical and mechanical properties of gel. In this study, polyvinyl alcohol (PVA) based hydrogel has been synthesized using glyoxal as crosslinker, influence diethylene glycol (DEG) porogen modifying its investigated. The resulting possesses unimodal distribution nanopores, content & sizes which are controlled by various dosages porogen. characterized FTIR spectroscopy confirms acetal linkage formation caused crosslinking reaction....
Linear low‐density polyethylene (LLDPE), biaxially oriented polypropylene (BOPP), terephthalate (PET) and Nylon 6 films used for food packaging application were subjected to e‐beam (EB) irradiation at different doses in the range of 0 80 kGy. The mechanical, barrier, optical thermal properties irradiated evaluated compared with non‐irradiated films. A notable decrease oxygen transmission rate (OTR) was observed BOPP specimens after irradiation, whereas PET samples, no significant change...
Hyperbranched copolymers self assembled from polymersomes to aggregates and encapsulated both hydrophilic/hydrophobic molecules but with varied retention proficiency depending upon the medium pH.
ABSTRACT Organogel copolymers of N ‐tertiary butyl acrylamide (in‐house synthesized) and acrylic acid were made by free radical polymerization using N,N ′‐methylene bisacrylamide as cross‐linker different proportions the comonomers. gels characterized spectroscopic analysis, swelling performances, morphological studies, thermal analysis. Swelling performances a function cross‐link density gels, dipole characteristic, structure, chemical composition solvent studied. deswelling kinetics in...
