摘要：

Self-oscillating gel is designed by copolymerizing the catalyst for the Belousov-Zhabotinsky (BZ) reaction with thermosensitive polymer. The cylindrical-shaped specimens of NIPAAm-co-(Ru(bpY)3 gel were prepared by copolymerizing (Ru(bpY)3) monomer as catalyst with NIPAAm as thermosensitive polymer. Tensile tests were performed with cross-head speed of 10 mu m/s in pure water at 20 degrees C. Stress-strain curves were plotted using tensile load measured by semiconductor gauge and strains calculated from observation of the gel. Fracture strain and Young's modulus were obtained from these curves. Also Poisson's ratio was estimated from the ratio of strains in longitudinal and radial directions.
