摘要： The present invention is directed to a electro-optic device comprising microcells having a sealing layer, the sealing layer comprising a poly(vinyl alcohol) homopolymer or poly(vinyl alcohol-co-ethylene) copolymer and a polyurethane. The scaling layer shows good barrier properties to a non-polar fluid and low moisture absorption. The sealing layer can be used to seal microcells of electro-optic devices.

摘要： Disclosed herein are electrospun fibrous matrix and its production method. The method mainly includes the steps of, mixing a first polymer and a drug to form a first mixture, and sonicating the first mixture until a plurality of microparticles are formed with the drug encapsulated therein; and mixing the plurality of microparticles with a second polymer to form a second mixture, subjecting the second mixture to a wet electrospinning process to form the electrospun fibrous matrix. The thus-produced electrospun fibrous matrix is characterized by having a plurality of first and second fibrils woven together, in which each second fibril has a plurality of drug-encapsulated microparticles independently integrated and disposed along the longitudinal direction of the second fibril. Also disclosed herein is a method for treating a wound of a subject. The method includes applying the present electrospun fibrous matrix to the wound of the subject.

摘要： The present invention provides a class of magnetic hydrogels with tissue-mimetic mechanical properties and photothermal welding/healing capability. In these hydrogels, a hybrid network involving aramid nanofibers, functionalized Fe3O4 nanoparticles, and polyvinyl alcohol (PVA) is accomplished by a stepwise assembly of the functional components. The engineered interactions between nanoscale constituents enable facile materials processing and confer a combination of excellent mechanical properties, magnetism, water content and porosity.

摘要： Microstructure manufacturing apparatuses and methods are disclosed herein that enable the production of microstructures in an efficient, cost-effective manner that produces precise, high-quality microstructure products. In the manufacturing process for a microneedle array, for example, a template can be contacted against a surface of a continuous layer of a viscous polymer and separated from the surface to form a plurality of projections. The projections can then be solidified and laser cut at a predetermined distance from the surface to form the microstructure.
