Ionic-covalent entanglement hydrogels from gellan gum, carrageenan and an epoxy-amine
TL;DR: In this paper, a "one pot" preparation of interpenetrating polymer network hydrogels with double network characteristics is presented, where a small addition of biopolymer dramatically increases the stiffness and strength of the epoxy-amine gels without affecting the large strain at failure value.

Rupture of rubber. I. Characteristic energy for tearing
R. S. Rivlin,A. G. Thomas +1 more
TL;DR: The resistance to tearing of a rubber vulcanizate is usually determined by loading in a specified manner a test-piece of the vulcanizer of standard shape, in which a notch has been produced, either in the molding process or by cutting the testpiece in a standard fashion.

Poly(vinyl alcohol) hydrogels: reinforcement of radiation-crosslinked networks by crystallization.
TL;DR: Aqueous poly(vinyl alcohol) solutions were crosslinked via electron-beam irradiation to form transparent hydrogels of varying crosslinking densities as discussed by the authors, which showed greatly improved mechanical properties (modulus, ultimate tensile strength, tear strength).
Journal ArticleDOI
Differential scanning calorimetry of crystallized PVA hydrogels
TL;DR: In this article, crosslinked poly(vinyl alcohol) hydrogels produced via electron beam irradiation of aqueous PVA solutions were crystallized via a two-stage dehydration-annealing process to produce swollen hydrogel of varying degrees of crystallinity.

James C. Bray,Edward W. Merrill +1 more
TL;DR: In this article, aqueous solutions of poly(vinyl alcohol) were submitted to varying doses of electron beam irradiation and the molecular weight between crosslinks, Mc, was calculated as a function of radiation dose, initial polymer concentration, and temperature.

Threshold fracture energies for elastomers
A. Ahagon,A. N. Gent +1 more
TL;DR: Fracture energies have been measured for two types of polybutadiene elastomer, crosslinked to various extents and torn under various conditions as discussed by the authors, with threshold values ranging from 40 to 80 jm−2, for samples torn at extremely low rates of tearing, at high temperatures, and in the swollen state.
