Elastic Properties of a Swollen PAAm-NIPA Copolymer with Various NIPA Contents
(Taylor & Francis Inc, 2014)
Copolymer based on cross-linked polyacrylamide (PAAm) having N-isopropylacrylamide (NIPA) was prepared and their elastic properties were studied as a function of NIPA contents. NIPA content dependency of the shear modulus, ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific Publ Co Pte Ltd, 2014)
Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N, N'-methylene bis (acrylamide) ...
Antimicrobial cerium ion-chitosan crosslinked alginate biopolymer films: A novel and potential wound dressing
(Elsevier Science Bv, 2017)
Wound dressings require good antiseptic properties, mechanical strength and, more trustably, natural material ingredients. Antimicrobial properties of cerium ions and chitosan are known and alginate based wound dressings ...
Evaluation of the fractal dimension of polyacrylamide during gelation and swelling
(Elsevier, 2021)
The photon scattering method was performed to monitor the free radical crosslinking copolymerization (FCC) of acrylamide (AAm) applied with N,N'-methylenebis (acrylamide) (Bis) in time. FCC experiments were conducted using ...
Fractal dimension and phase transition of graphene oxide (GO) doped polyacrylamide
(Elsevier Sci Ltd, 2020)
Graphene Oxide (GO)- Polyacrylamide composites prepared between 5 and 50 mu l GO were performed by Fluorescence Spectroscopy. The phase transition performed on the composites was measured by calculating the critical ...
Electrical, optical and mechanical properties of chitosan biocomposites
(Sage Publications Ltd, 2020)
In this work, chitosan/graphene nanoplatelets (CS/GNP) and chitosan/multi-walled carbon nanotube (CS/MWCNT) biocomposite films were prepared using a simple, eco-friendly and low-cost method. The electrical, optical and ...
Electrical, mechanical, and optical changes in MWCNT-doped PMMA composite films
(Sage Publications Ltd, 2020)
In this study, we report the preparation of poly (methyl methacrylate)/multi-walled carbon nanotube (MWCNT) composite thin films by simple and efficient solution mixing and ultrasonic method and the electrical, optical, ...
Electrical, optical and mechanical properties of PS/GNP composite films
(Taylor & Francis Ltd, 2018)
In this study, the electrical, optical and mechanical properties of polystyrene (PS) thin films added graphene nanoplatelet (GNP) have been investigated. Surface conductivity (sigma), absorbance intensity (A) and tensile ...
Effect of Calcium Ion Concentration on Small Molecule Desorption from Alginate Beads
(Taylor & Francis Inc, 2014)
Spherical alginate beads were prepared by ionotropic gelation of sodium alginate through the use of calcium ions. Pyranine (Py) was added to the alginate solution as a small molecule probe for fluorescence studies. Desorption ...
Antibacterial nano cerium oxide/chitosan/cellulose acetate composite films as potential wound dressing
(Pergamon-Elsevier Science Ltd, 2020)
Novel chitosan and cellulose acetate polymer composites with nanosized cerium oxide were prepared as potential wound dressing materials. Chitosan and cellulose acetate are natural polymer derivatives with biocompatible ...
