Elastic Properties of Crosslinked Polymers

At first a survey is given on the thermodynamics of rubber-elasticity and the results of the statistical theory of molecular networks. Experimental data of torsional vibrations, stress—strain measurements (simple extension and uniaxial compression) and photoelastic properties in dependence of temperature are reported. The measurements have been carried out on dry and swollen crosslinked polymer...

Physical properties of polyacrylamide gels probed by AFM and rheology

Polymer gels have been shown to behave as viscoelastic materials but only a small amount of data is usually provided in the glass transition. In this paper, the dynamic moduli G′ and G′′ of polyacrylamide hydrogels are investigated using both an AFM in contact force modulation mode and a classical rheometer. The validity is shown by matching of the two techniques. Measurements are carried out o...

Preparation of DNA-crosslinked polyacrylamide hydrogels.

Mechanobiology is an emerging scientific area that addresses the critical role of physical cues in directing cell morphology and function. For example, the effect of tissue elasticity on cell function is a major area of mechanobiology research because tissue stiffness modulates with disease, development, and injury. Static tissue-mimicking materials, or materials that cannot alter stiffness onc...

Formation and Structure of Polyacrylamide Gels

Acrylamide and N,N-methylenebis(acry1amide) (AAm-Bis) copolymerization has been investigated in water at a monomer concentration of 1.8 w/v %. Conversion of monomer and pendant vinyl groups was measured as a function of the reaction time up to the onset of macrogelation. Experimental results indicate that 80% of pendant vinyl groups are consumed by cyclization reactions. When the monomer concen...

Demonstration of rhodanese activity in polyacrylamide gels.

Rhodanese activity from crude extracts of Thiobacillus sp. strain IV-85 was demonstrated in polyacrylamide gels after incubation in the reaction mixture by staining with dichloroindophenol in the presence of methylphenazonium methosulfate. The sensitivity of the staining system was found to be 8 x 10 moles of sulfite.
