Elasticity, tear strength, and strength of adhesion of soft PVC gels

Journal of Applied Polymer Science, 1986
AbstractAn experimental study is described of the tensile modulus E of elasticity, tear strength Gc, and strength Ga of adhesion to a Mylar substrate, for PVC gels prepared with a wide range of PVC concentrations and with four different plasticizers. The modulus E, measured under quasiequilibrium conditions, was found to be approximately proportional ...

Gel properties of potato protein and the isolated fractions of patatins and protease inhibitors – Impact of drying method, protein concentration, pH and ionic strength

Food Hydrocolloids, 2019
The use of plant protein in food products is increasing. Potato protein gelation is scarcely documented, therefore potato protein gel properties were tested for two whole protein isolates (freeze dried or spray dried) and the purified sub-fractions ...

Insight into the mechanism of myofibrillar protein gel influenced by konjac glucomannan: Moisture stability and phase separation behavior.

Food Chemistry, 2021
The effect and mechanism of myofibrillar protein (MP) gelation influenced by konjac glucomannan (KG) addition were studied. The KG addition significantly improved gel strength and water holding capability (WHC) of MP-KG composite gel, but it had additive

Experimental research of high strength thermally stable organic composite polymer gel

Journal of Molecular Liquids, 2018
Polymer gel has been successfully applied for enhanced oil recovery (EOR) in heterogeneous reservoirs. A novel composite polymer gel was developed based on amphiphilic polymer, resorsinol/hexamethylenetetramine, silica dioxide (SiO2) and surfactant under

A high strength, low friction, and biocompatible hydrogel from PVA, chitosan and sodium alginate for articular cartilage.

Carbohydrate Polymers, 2022
Developing articular cartilage substitutes required a combination of high compressive strength, excellent biocompatibility and low friction. Despite great success in tough hydrogels, this combination was hardly realized.

Polyampholytes superabsorbent nanocomposites with excellent gel strength

Composites Science and Technology, 2007
A series of novel polyampholyte superabsorbent nanocomposites with excellent gel strength were synthesized by in situ solution polymerization in aqueous solution. Acrylic acid and acryloyloxyethyl trimethyl ammonium chloride (DAC) were employed as ionic monomers and montmorillonite (MMT) was used as inorganic component.

Parametric study of strength of silica gels

Journal of Non-Crystalline Solids, 1994
Abstract Cylindrical gel bodies were produced by using Si(OC2H5)4, C2H5OH and H2O with various catalysts. A systematic parametric study of gel strength and microstructure as a function of C2H5OH/H2O molar ratio and catalyst concentration in sol, catalyst type as well as aging time, was conducted.

Gel strength and rate of gelation of soft polymers

Dental Materials, 1991
A rheometer was used to characterize the gelation rate of six commercial short- to medium-term (chairside intra-oral gelation) denture soft-lining materials. Shear puncture force was measured from one to 60 days for six short- to medium-term materials as well as for three heat-cured (polymerizable) materials.

Dynamic viscoelasticity of fibrin gels: Dependence on ionic strength

Thrombosis Research, 1976
Abstract The dynamic rigidity and loss moduli of fibrinogen solutions with various ionic strengths are determined during clotting. The kinetic analysis of the clotting curves indicates that the fibrin gels formed at high and low ionic strengths consist of non-flexible thick fibrous bundles, while those formed at moderate ionic strengths consist of ...

Characterization of Crosslinked Gel Kinetics and Gel Strength by Use of NMR

SPE Reservoir Evaluation & Engineering, 2008
Summary Highly crosslinked gels are used in high-permeability reservoirs to achieve appropriate fluid-loss control during well completion and workover operations. Crosslinked gels are also used to shut off unwanted gas and/or water influx into production wells and to improve the conformance of the near-wellbore injection profile in ...
