EFFECT OF CONFINED GEOMETRY SIZE ON CRYSTALLIZATION BEHAVIORS OF N-ALKANE
Polymers often crystallize into metastable phases when cooling from the melt. There is a broad class of metastable states in polymers and the metastability is dictated by their microscopic phase size.2 Since it is very important to clarify the size effect of metastable states in polymers, in the recent years, considerable attention has been paid to investigate the confined crystallization of polymers, which usually occurs in block copolymers, graft polymers and polymer blends.3-4 However, it is difficult to propose a quantitative formula to describe the transition dynamics of metastable states in these polymers, due to the multiple hierarchical structure and various domain sizes in these states. Compared to the complex polymer materials, normal alkanes CnH2n+2, n-alkanes, abbreviated as Cn, as the most fundamental organic series, can provide welldefined model systems for studying the complex crystallization behaviors of polymer materials, surfactants, lipids, and liquid crystals.5 Therefore, the investigation of n-alkane in confined space is beneficial to better understand the confined crystallization behaviors and ultimate properties of many polymer materials.
