A novel type of liquid gating technology has been developed to prepare a polyethylene oxide (PEO) single-crystal film, and the crystal growth was observed via atomic force microscopy. The self-seeding method has been widely used in the preparation of polymer single crystals, but the mechanism through which single polymer crystals are formed via the combination of liquid gating technology and the self-seeding method remains unclear. To elucidate the mechanism of this process, a series of experiments were conducted in which a dilute polymer solution was sprayed onto a mica substrate to form a single-crystal film through liquid gating technology to study the effect of the crystallization time on the morphology of a thiol PEO (mPEO-SH) crystal. Based on this research, it was found that liquid gating helps to prevent twinning during crystal growth. The combination of liquid gating and self-seeding technology thus provides a new strategy for polymer single-crystal growth.

液态浇注技术制备聚环氧乙烷单晶及形貌设计策略

开发了一种新型的液体浇注技术来制备聚环氧乙烷 (PEO) 单晶薄膜，并通过原子力显微镜观察晶体生长。自晶种法已广泛应用于聚合物单晶的制备，但液态浇注技术与自晶种法相结合形成聚合物单晶的机理尚不清楚。为了阐明这一过程的机理，进行了一系列实验，其中将稀聚合物溶液喷涂到云母基板上，通过液体浇注技术形成单晶薄膜，研究结晶时间对云母形貌的影响。硫醇 PEO (mPEO-SH) 晶体。根据这项研究，发现液体浇口有助于防止晶体生长过程中的孪晶。
