Abstract

Polymerization within nanoconfinement offers a versatile approach to creating nanostructured materials with unique properties and a wide range of applications. Therefore, it is important to understand the nature of polymerization in both hard and soft nanoconfinements, which have been classified based on their mechanical modulus in this perspective. We also evaluate factors affecting the kinetics of polymerization within different templates. Template walls, mainly in hard nanoconfinement, may have a catalytic effect and enhance initial polymerization rates. Additionally, increased termination rates as well as lower limiting conversion are observed in those templates. On the other hand, we discuss the self-assembled amphiphilic molecules in selective solvents, known as lyotropic liquid crystals (LLCs), as a common class of soft templates inducing nanoconfinement during polymerization. Key factors such as initiator type, monomer chemistry, crosslinking density, and arrangement of the micelles in LLC templates are brought into a framework in this perspective to analyze their impact on polymerization rates and structural retention in LLCs.

纳米聚合:溶致液晶作为软模板的优势
纳米约束下的聚合提供了一种通用的方法来制造具有独特性能和广泛应用的纳米结构材料。因此,了解硬纳米和软纳米颗粒的聚合性质是很重要的,这是基于它们的力学模量来分类的。我们还评估了影响不同模板内聚合动力学的因素。模板壁(主要是在硬纳米约束下)可能具有催化作用并提高初始聚合速率。此外,在这些模板中观察到增加的终止率和较低的极限转换。另一方面,我们讨论了选择性溶剂中自组装的两亲分子,称为溶致液晶(LLCs),作为聚合过程中诱导纳米限制的一类常见软模板。从这个角度出发,将引发剂类型、单体化学、交联密度和LLC模板中胶束的排列等关键因素纳入一个框架,分析它们对LLC中聚合速率和结构保留率的影响。
