Abstract

We studied experimentally and theoretically how the network topology influences the mechanical properties and swelling of polymer networks. The properties of monofunctional and polyfunctional networks were compared. The cross-link functionality distribution of the polyfunctional networks is a power function. Such networks are also called scale-free networks. The ultimate tensile strength and ultimate tensile strain of a polyfunctional network appeared to be 1.4 and ~2 times as high as the respective parameters for a monofunctional network. For assessing the long-term strength of polymer networks, we used cyclic straining. The number of cycles from the onset of an experiment to the breakdown of the test sample for a scale-free polymer network was 56 to 60 times the number of cycles for a monofunctional network. We used the lattice-type model of solutions and derived an equation relating the chemical potential of the solvent or plasticizer in a swollen scale-free polymer network to the network parameters and the volume fraction of the polymer. The experimental results verified the validity of our theoretical analysis.
