Semicrystalline shape-memory elastomers are molded into deformable geometrical features to control adhesive interactions between elastomers and a glass substrate. By mechanically and thermally controlling the deformation and phase-behavior of molded features, we can control the interfacial contact area and the interfacial adhesive force. Results indicate that elastic energy is stored in the semicrystalline state of deformed features and can be released to break attractive interfacial forces, automatically separating the glass substrate from the elastomer. Our findings suggest that the shape-memory elastomers can be applied in various contact printing applications to control adhesive forces and delamination mechanics during ink pickup and transfer.
半结晶形状记忆弹性体被模制成可变形的几何形状，以控制弹性体与玻璃基板之间的粘附相互作用。通过机械和热方式控制模制形状的变形和相行为，我们可以控制界面接触面积和界面粘附力。结果表明，弹性能量存储在变形形状的半结晶状态中，并可以释放以打破有吸引力的界面力，从而自动将玻璃基板与弹性体分离。我们的研究结果表明，形状记忆弹性体可应用于各种接触印刷应用中，以控制在油墨拾取和转移过程中的粘附力和分层力学。
