In the application areas of polymer hydrogels, precise information on their molecular constitution as well as their elastic properties is required. Several interesting molecular features control the elastic properties of the hydrogels. In this chapter, we describe general properties of hydrogels formed by free-radical crosslinking copolymerization of vinyl/divinyl monomers in aqueous solutions....

Monte Carlo simulations of mono– and polydisperse two–dimensional crystals are reported. The particles in the studied system, interacting through hard–core repulsive Yukawa potential, form a solid phase of hexagonal lattice. The elastic properties of crystalline Yukawa systems are determined in the NpT ensemble with variable shape of the periodic box. Effects of the Debye screening length (κ), ...
