  公开号：US10133174B2

  公开（公告）日：2018-11-20

  A method of fabricating a structure includes disposing a liquid photoreactive composition on a substrate, exposing a portion of the liquid photoreactive composition to laser light of sufficient intensity and wavelength to cause polymerization via two-photon excitation of the two-photon sensitizer and polymerization of a portion of the liquid photoreactive composition thereby providing an exposed composition; and developing the exposed composition to provide the structure. The liquid composition includes: at least one cationically polymerizable polyepoxide; at least one compound comprising free-radically polymerizable groups; an effective amount of a two-photon photoinitiator system, wherein the weight ratio of component (a) to component (b) is from 25:75 to 75:25, inclusive. The two-photon photoinitiator system includes a two-photon sensitizer and an aromatic onium salt. The liquid photoreactive composition may contain less than about one percent by weight of organic solvent.

  一种制造结构的方法包括：将液态光活性组合物置于基底上，将液态光活性组合物的一部分暴露于足够强度和波长的激光，以通过双光子敏化剂的双光子激发和液态光活性组合物一部分的聚合引起聚合，从而提供暴露的组合物；以及显影暴露的组合物以提供结构。液体组合物包括：至少一种可阳离子聚合的聚环氧化物；至少一种包含可自由基聚合基团的化合物；有效量的双光子光引发剂体系，其中组分（a）与组分（b）的重量比为 25:75 至 75:25（含）。双光子光引发剂体系包括双光子敏化剂和芳香族鎓盐。液态光活性组合物中有机溶剂的含量可少于约百分之一（按重量计）。
