The frictional properties of PVA cast gel prepared under different conditions have been investigated. Optimum drying humidity (60%RH) or low drying temperature conditions caused a decrease in the coefficient of friction in the reciprocating test. As the drying humidity increased, the surface of the gel became flat and smooth. On the other hand, when the drying temperature became lower, lubrication improved by elution of the polymer. In addition, the layered PVA cast gel maintained a lower coefficient of friction throughout the reciprocating test. From the results, it was shown that the excellent frictional properties could be maintained by controlling the preparation conditions.
