Triple‐shape‐memory polymer films created by forced‐assembly multilayer coextrusion

22-Sep-2016 | Shanzuo Ji, Jia Wang, Andrew Olah, Eric Baer, Journal of Applied Polymer Science, 2016

ABSTRACT Triple‐shape‐memory polymers are capable of memorizing two temporary shapes and sequentially recovering from the first temporary shape to the second temporary shape and eventually to the permanent shape upon exposure to a stimulus. In this study, unique three‐component, multilayered ...
