| Abstract;Application of thermomechanometry to the measurement of hydrogels containing a large amount of water was carried out by static and dynamic methods. A thermomechanical analyzer(TMA) equipped with a quartz compression probe which was immersed in water was used. Polysaccharide hydrogels containing ca. 98% water were measured. Creep of hydrogels in water was analyzed in a stress range from 1.04*103 to 5.2*103 Pa and loading rate from 0.3*103 to 3.0*103 Pa min-1. Stress relaxation was measured in compressed ratio range from 0.02 to 0.45mm-1 and in compressing rate was 0.09 to 0.15mm-1min-1. Dynamic viscoelasticity was measured by TMA when dynamic Young's modulus which was larger than 1*104Pa in frequencies range from 0.02-0.5Hz. (author abst.) |
