残留膨潤によるコンポジットエラストマの変形応答

抄録

A swelling of a polymeric gel is a phenomenon to absorbs a solvent and largely deform with its volume change, while a residual swelling is a phenomenon that leads to a change in shape of a thin elastomer without a volume change by migration of free polymer chains. In order to drive the shape changes of thin composite elastomers due to residual swelling, consisting of two elastomer beams with a stiffness ratio, it is necessary to clarify the effect of residual swelling on the shape changes. Here we investigate the effect of the thickness ratio of bilayer on the bending curvatures and estimate the residual stain.
