METHODS FOR PREPARING CUSTOMIZED POLYMERIC ARTICLES
摘要
The present invention provides a method for preparing a customized polymeric article including: providing two mold half-sections, each half-section having an outer surface and an inner surface; assembling the two mold half-sections to form a mold assembly such that the inner surfaces define a cavity there between; applying one or more magnetic fluids to the inner surface of a mold half-section; inserting a fluid polymeric material into the cavity; controllably applying a magnetic field to the magnetic fluids to form a customized reversible surface in accordance with a predetermined specific surface topography; subjecting the mold assembly to conditions sufficient to effect polymerization or hardening of the fluid polymeric material; and separating the two mold half-sections. Articles prepared by the method also are provided.
