A method of forming an image having multiple phases is disclosed herein. The method includes forming exposed and unexposed areas, the exposed areas comprising a first polymer network exhibiting first and second phases that are chemically connected and have different refractive indices, the first phase being continuous, and the second phase comprising a plurality of structures dispersed within the first phase, and the unexposed areas comprising a second polymer network comprising third and fourth phases that are chemically connected and have different refractive indices, the third phase being continuous, and the fourth phase comprising a plurality of structures dispersed within the third phase. The first and second polymer networks are chemically connected, and morphology formed by the first and second phases is different than that formed by the third and fourth phases.

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:
Laser induced thermal embossing (LITE) films used to make microreplication tools, liners, and products such as laser induced thermal imaging (LITI) donor films. The LITE tools or liners have a microstructured surface selectively imposed upon them as determined by an area of imaging the LITE films against one or more microreplication tools. An orientation between the laser imaging lines and LITE films can be selected to produce various microreplication patterns on the tools. The LITE tools can be made having a structure on structure pattern including a microstructured pattern with a nanostructured surface. The LITE liners can be combined with other films to form products. The LITE films can also be coated with a transfer layer to form a LITE donor film with a structured transfer layer.
