Abstract

<p indent="0mm">The matter at surfaces or interfaces exhibits physical properties that differ from the bulk. The physiochemical questions at surfaces/interfaces are of fundamental importance for chemistry and material science. In recent years, new crystallization phenomena related to surfaces/interfaces have emerged and have caused attention. Based on the research work of our team, this article summarizes the recent results on this topic, focusing on the physical mechanism behind the different experiment findings in various systems. First, several basic concepts are introduced, especially surface tension and nucleation. Then, several examples are summarized in detail, including surface freezing of long-chain alkanes, prefreezing of polymers on solid substrates, metastable states enhancement induced by surface freezing, and the impact of surface adsorption on crystallization. After that, the relationships among different surface-related crystallization phenomena are discussed. Finally, the unsolved questions in polymer surface crystallization are proposed.
