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.
摘要:
Provided is a method of making microarrays that includes providing a substrate with discrete first microfeatures that have a first profile, and depositing vapor-coated materials onto the first microfeatures to form second microfeatures having a second profile that is substantially different from the first profile. Also provided is a method of adding a replication material to the vapor-coated microfeatures to form a mold. Microarrays made by this method can be used as substrates for surface-enhanced Raman spectroscopy (SERS).

摘要:
A flexible flow field separator includes a substrate layer formed of a flexible material and having first and second surfaces. A structured flow field pattern is defined on the first surface of the substrate layer. The structured flow field pattern defines one or more fluid channels. The separator includes a first layer formed of one or more metals and disposed on the first surface of the substrate layer. The first layer is formed of an electrically conductive material. The separator further includes a second layer disposed on the second surface of the substrate layer. The second layer is formed of a flexible electrically conductive material. The first layer contacts the second layer at one or more locations to define an electrical connection between the first and second layers.
摘要:
An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.
