In this research, spherical surface molding of polymer using a liquid mold system is described. A liquid droplet has spherical surfaces at the liquid-liquid interface due to interfacial tension. The curvature of the spherical surface is determined by the degree of interfacial tension applied at each interface. Interfacial tension between some liquids was measured, and the shape of a photopolymer droplet between the liquids was calculated. Ultraviolet light was irradiated onto a photopolymer droplet located at the liquid-liquid interface, using a superhigh-pressure mercury lamp. Photopolymer droplets solidified and lens-shaped objects were produced. Cross sections of these objects were observed, and the curvatures of the spherical sufaces were found to correlate with the interfacial tension. A spherical solid was formed at a water/salt solution interface. The possibility of forming various spherical surfaces by exploiting liquid-liquid interfaces was revealed.

在这项研究中，球面成型的聚合物使用液体模具系统进行了说明。由于界面张力，液滴在液-液界面处具有球形表面。球形表面的曲率由施加在每个界面处的界面张力的程度决定。测量了一些液体之间的界面张力，并计算了液体之间光聚合物液滴的形状。使用超高压汞灯将紫外光照射到位于液-液界面处的光聚合物液滴上。光聚合物液滴固化和透镜形状的物体产生。观察了这些物体的横截面，发现球面的曲率与界面张力相关。在水/盐溶液界面处形成球形固体。揭示了利用液-液界面形成各种球形表面的可能性。
