    Abstract: The present invention provides a porous sheet production method comprising the steps of: a) producing a polymer resin sheet comprising a supercritical extraction target substance which dissolves in a supercritical fluid; and b) forming pores in the polymer resin sheet by pouring a supercritical fluid into the polymer resin sheet and thereby extracting the supercritical extraction target substance comprised in the polymer resin sheet. The present invention also provides a porous sheet produced by means of the method.

    Abstract: The invention provides microporous foam suitable for medical applications and methods for preparing these foams. The microporous foams are of controlled pore size that may be utilized in a variety of applications. In general, the foams are characterized in that the pores are continuous and open-celled. In preparing the foams, an organic polymer is melted and combined with a selected solid crystalline fugitive compound, that melts above about 25 DEG C, and/or that sublimates at above about 25 DEG C or can be extracted, to produce a substantially isotropic solution. The solution is cooled under controlled conditions to produce a foam precursor containing the solidified fugitive composition dispersed through a matrix of the organic polymer. Crystals of fugitive composition are then removed by solvent extraction and/or sublimation, or like process to produce microcellular foams having a continuous, open-cell structure. The technique may also be utilized to produce filamentous foams, hollow fiber, catheters, and tubes by extrusion, sheets by casting and can also be applied for the creation of foamy or microtextured sufaces on solid polymeric substrates or microtextured organic polymeric surfaces.

    Abstract translation: 本发明提供适用于医疗应用的微孔泡沫和制备这些泡沫的方法。 微孔泡沫具有受控的孔径，可用于各种应用中。 通常，泡沫的特征在于孔是连续的和开孔的。 在制备泡沫体时，将有机聚合物熔化并与选择的熔体高于约25℃的固态晶体化合物混合，和/或在高于约25℃升华或可以提取，以产生基本上各向同性的溶液 。 将溶液在受控条件下冷却以产生包含通过有机聚合物基质分散的固化的缓冲组合物的泡沫前体。 然后通过溶剂萃取和/或升华或类似方法除去挥发性组合物的晶体以产生具有连续的开孔结构的微孔泡沫。 该技术还可以用于通过挤出，片材通过流延来生产丝状泡沫，中空纤维，导管和管，并且还可以用于在固体聚合物基底或微结构的有机聚合物表面上产生泡沫或微结构的表面。
