Abstract

Surface wave velocity of the methylcellulose (MC) hydrogels in the drying process was measured with three different molecular weights. Surface wave velocity increased with drying time for all samples but there was a period in which the surface wave velocity kept an almost constant value for two samples. A possible explanation for the period was made from the numerical calculation of surface wave velocity using simplified layer model.
