METHODS FOR CHANGING THE SHAPE OF A SURFACE OF A SHAPE MEMORY POLYMER ARTICLE
摘要
<p>Methods for changing the shape of a surface of an article are disclosed. The methods may include providing a liquid polymer precursor, casting the precursor against a first tool assembly, curing the precursor to form a shape memory polymer substrate, deforming one or more surfaces of the substrate, and mobilizing the shape memory polymer to shift the deformed surface of the substrate from a deformed shape to a pre-set shape.</p>
