一体发泡的微观结构物
摘要：
本发明部分涉及一种包括聚合物泡沫的物品，该聚合物泡沫具有带表面微观结构(14)的表面，该表面微观结构具有至少一个约10微米或者10微米以上、优选的是50微米或者50微米以上的大小或者尺寸。所述微观结构的最大大小(除非它是连续的、肋状的结构)为约300微米或者300微米以下，优选的是200微米或者200微米以下，并且其最大高度通常为1000微米或者1000微米以下，优选的是750微米或者750微米以下，而最小高度为200微米或者200微米以上，优选的是300微米或者300微米以上。所述发泡物可以以多种形式提供，包括杆状、圆柱状、板状等等。在以板状形式提供的发泡物的优选实施例中，所述发泡物具有一对主要表面，其中一个或者两个主要表面带有表面微观结构。发泡物的衬里和结构包括多个孔隙，该孔隙优选地具有基本小于所述微观结构的最小截面尺寸或者大小的平均尺寸。
摘要（英）：

The invention is directed in part to an article that includes a polymer foam having a surface with surface microstructures, the surface microstructures have at least one extent or dimension of about 10 microns or more, preferably 50 microns or more. A maximum extent (unless it is a continuous rib-like structure) the microstructure is about 300 microns or less, preferably 200 microns or less, and generally a maximum height of 1000 microns or less, preferably 750 microns or less and a minimum height of 200 microns or more, preferably 300 microns or more. The foamed article may be provided in a variety of shapes, including a rod, a cylinder, a sheet, etc. In a preferred embodiment where the foam is provided in the form of a sheet, the foam has a pair of major surfaces, one or both of which can be provided with surface microstructures. The foam backing and microstructures include a plurality of voids, which voids are preferably of a mean size substantially less than the smallest cross-sectional dimension or extent of the microstructures.
