梳形聚合物，密集接枝聚合物刷，近年来已被广泛研究。由于接枝密度和侧链长度的差异，它们具有各种分支拓扑结构。这种差异带来了许多新的构象和性质。梳状聚合物已经在自然界中发挥了特殊的功能，如清洁肺气道的蛋白聚糖。受蛋白聚糖的启发，研究人员现在正在制备具有功能基团或侧链的梳状聚合物。在药物传递载体、分子压力传感器和固体光学材料等方面的工作已有报道。通常使用三种合成策略来制备梳形聚合物，即“接枝至”、“自接枝”和“通过接枝”。其中，“穿通接枝”是制备接枝率为100%且侧链长度相同的梳形聚合物的唯一途径。
INTRODUCTION Comb polymers, densely grafted polymer brushes, have been widely studied in recent years. They have various branching topologies because of the differences in grafting densities and side-chain lengths. Such differences bring in many new conformations and properties. Comb polymers have already worked in nature with particular functions such as proteoglycans which clean lung airways. Inspired by the proteoglycans, researchers are now preparing comb polymers with functional groups or side chains. Many works in drug-delivery carriers, molecular pressure sensors, and solid optical materials have been reported. Three synthetic strategies for preparing comb polymers are usually used, that is, “grafting to,” “grafting from,” and “grafting through.” Among them, “grafting through” is the only way to prepare comb polymers with 100% grafting density and side chains having the same length.
