Colloidal lithography for fabricating patterned polymer-brush microstructures
We exploit a series of robust, but simple and convenient colloidal lithography (CL) approaches, using a microsphere array as a mask or as a guiding template, and combine this with surface-initiated atom-transfer radical polymerization (SI-ATRP) to fabricate patterned polymer-brush microstructures. The advantages of the CL technique over other lithographic approaches for the fabrication of patte...
متن کاملPolymer pen lithography.
We report a low-cost, high-throughput scanning probe lithography method that uses a soft elastomeric tip array, rather than tips mounted on individual cantilevers, to deliver inks to a surface in a "direct write" manner. Polymer pen lithography merges the feature size control of dip-pen nanolithography with the large-area capability of contact printing. Because ink delivery is time and force de...
متن کاملLithographically induced self-construction of polymer microstructures for resistless patterning
We have discovered and developed a method that can directly pattern polymer microstructures of arbitrary shapes without using a resist, exposure, chemical development, and etching. A mask with protruded patterns is placed a distance above an initially flat polymer film cast on a substrate. During a heating cycle that raises the temperature above the polymer’s glass transition temperature and th...
متن کاملStructured polymer brushes by AFM lithography.
Structured polymer surfaces have gained increased attention in various research fields during the past few years. By structuring of polymer surfaces, in particular of polymer brushes, functional surfaces with defined properties, for example for the study of cell adhesion and of cell alignment, have been prepared. Moreover, patterning of polymer brushes allows the alteration and control of their...
متن کامل"Self-Shaping" of Multicomponent Drops.
In our recent study we showed that single-component emulsion drops, stabilized by proper surfactants, can spontaneously break symmetry and transform into various polygonal shapes during cooling [ Denkov Nature 2015 , 528 , 392 - 395 ]. This process involves the formation of a plastic rotator phase of self-assembled oil molecules beneath the drop surface. The plastic phase spontaneously forms a ...
