We present a review of the theoretical and experimental evidence for the peculiar properties of comb copolymers, demonstrating the uniqueness of these materials among other polymer architectures. These special properties include an increase in stiffness upon increasing side-chain length, the spontaneous curvature of adsorbed combs, rod-globule transition, and specific intramolecular self-assembly. We also propose a theory of chemically heterogeneous surface nanopattern formation in ultrathin films of comblike macromolecules containing two different types (A and B) of incompatible side chains (so-called binary combs). Side chains of the binary combs are strongly adsorbed on a surface and segregated with respect to the backbone. The thickness of surface domains formed by the B side chains is controlled by the interaction with the substrate. We predict the stability of direct and inverse disc-, torus- and stripelike nanostructures. Phase diagrams of the film are constructed.
我们回顾了梳状共聚物特殊性质的理论和实验证据，证明了这些材料在其他聚合物结构中的独特性。这些特殊性质包括侧链长度增加时刚度的增加、吸附梳的自发曲率、棒状-球状转变以及特定的分子内自组装。我们还提出了一种理论，用于解释含有两种不同类型（A 和 B）不相容侧链（所谓的双组分梳）的梳状大分子的超薄膜中化学异质表面纳米图案的形成。双组分梳的侧链强烈吸附在表面上并与主链分离。由 B 侧链形成的表面域的厚度受与基底的相互作用控制。我们预测了直接和反向盘状、环形和条带状纳米结构的稳定性。构建了薄膜的相图。
