Liquid marbles (LMs) with a cubic shape are created by using various vinyl monomers as an inner liquid and polymer plates with mm size as a stabilizer. The relationship between the surface tension of the vinyl monomers and formability of the LMs is investigated. LMs can be fabricated using vinyl monomers with surface tensions of 42.7-40.3 mN m. The cubic polymer particles are successively synthesized via free-radical polymerizations by irradiation of the cubic LMs with UV light in a solvent-free manner. In addition, controlling the number of polymer plates per one LM, the shape of the plate or the coalescence of the LMs can lead to production of polymer particles with desired forms (e.g., Platonic and rectangular solids) that correspond to the shapes of the original LMs.
通过使用各种乙烯基单体作为内部液体以及毫米尺寸的聚合物板作为稳定剂来制备立方体形的液滴弹（LMs）。研究了乙烯基单体的表面张力与液滴弹可成型性之间的关系。可以使用表面张力为42.7 - 40.3 mN/m的乙烯基单体来制造液滴弹。通过在无溶剂的方式下用紫外光照射立方体形的液滴弹，经由自由基聚合连续合成立方体形聚合物颗粒。此外，控制每个液滴弹的聚合物板数量、板的形状或液滴弹的聚结可导致生产出具有与原始液滴弹形状相对应的所需形状（例如，柏拉图体和长方体）的聚合物颗粒。
