Abstract

Particle double-network gels (P-DN gels) consist of two kinds of network structure. The first structure is made by hard and rigid particles of polyelectrolyte gels and the second structure is made by a soft and elastic network of neutral gels. Recently, we have developed improved P-DN gels for 3D gel printers by grinding the 1st gel particle to be finer. In this work, we report the internal structure of P-DN gels by Scanning Microscopic Light Scattering (SMILS) and the mechanical properties by tensile tests and repeated tensile tests. From the results of SMILS measurements, we infer the motion of the 2nd gels network. Increasing the concentration of crosslinking agents for 2nd gels, the motion slowed down. From the tensile tests of P-DN gels, we observed that the fracture strain of P-DN gels depends on the size of 1st gel particles. This implies that the hardness of P-DN gels can be changed easily by changing the size of 1st gel particles. Furthermore, we observed the hysteresis of P-DN gels due to plasticity by repeated tensile tests.
