本文重点介绍了近年来在LCPO物理化学组研究的一些原始嵌段共聚物特性，给出了我们对嵌段共聚物在溶液（无序状态和自组装）和本体（纳米组织膜）中的物理特性的看法。特别是，我们表明，除了柔性-柔性嵌段共聚物链的经典结果，结构（嵌段的刚性，环化等）以及外部参数（温度，pH值，离子强度）在由具有受控结构的嵌段共聚物制成的材料的不同阶段中发挥重要作用。各种嵌段共聚物系统的性质研究，在水性或有机介质中，讨论在自由嵌段共聚物链，自组装和纳米结构/纳米组织的薄膜与技术的帮助下，如散射（光，X-射线，中子）和成像（AFM，TEM）。
This article highlights some original block copolymer properties that have been studied in recent years at the Physico-Chemistry group at the LCPO, giving our view on the physics of block copolymers in solutions (disordered state and self-assembly) and in the bulk (nano-organized films). In particular, we show that beyond the classical results on flexible-flexible block copolymer chains, the architecture (rigidity of the blocks, cyclization, etc) as well as external parameters (temperature, pH, ionic strength) play an important role in the different phases of a material made from block copolymers with controlled architectures. The properties of the various block copolymer systems investigated, in aqueous or organic media, are discussed in terms of free block copolymer chains, self-assemblies and nano-structured/nano-organized films with the aid of techniques such as scattering (light, X-rays, neutrons) and imaging (AFM, TEM).
