自20世纪60年代初以来,人们一直在研究基于聚苯乙烯的嵌段共聚物,由于可持续材料的重要性日益增加,人们对它的兴趣越来越大。多糖是可再生的,通常可生物降解,通常无毒,并提供广泛的结构多样性,产生非常多样化的材料,提供广泛的性质和应用。含有一个或多个多糖嵌段和一个或多个合成嵌段的嵌段共聚物可以使用多种方法合成,通过直接偶联或扩链方法。在这里,我们回顾了目前的合成方法制备含多糖的嵌段共聚物。我们还讨论了这类嵌段共聚物的既定和新兴应用,如它们作为药物递送载体,水凝胶局部药物递送,和表面活性剂/界面剂稳定界面,包括那些在多糖/合成聚合物共混物。
Polysaccharide-based block copolymers have been studied since the early 1960s and command growing interest due to the increasing importance of sustainable materials. Polysaccharides are renewable, often biodegradable, generally nontoxic, and offer wide structural variety, yielding remarkably diverse materials that provide a wide range of properties and applications. Block copolymers containing one or more polysaccharide blocks and one or more synthetic blocks can be synthesized using a variety of methods, either through direct coupling or chain extension approaches. Here we review current synthetic methods for the preparation of polysaccharide-containing block copolymers. We also discuss established and emerging applications of this class of block copolymers, such as their use as drug delivery vehicles, hydrogels for localized drug delivery, and surfactants/interfacial agents for stabilizing interfaces, including those in polysaccharide/synthetic polymer blends.
