We report a “grafting to” method for stably grafting high-molecular-weight polymer brushes on both active and inert surfaces using tadpole-like single-chain particles (TSCPs) with an interactive “head” as grafting units. The TSCPs can be efficiently synthesized through intrachain cross-linking one block of a diblock copolymer; the “head” is the intrachain cross-linked single-chain particle, and the “tail” is a linear polymer chain that has a contour length up to micrometers. When grafted to a surface, the “head”, integrating numerous interacting groups, can synergize multiple weak interactions with the surface, thereby enabling stable grafting of the “tail” on both active and traditionally challenging inert surfaces. Because the structural parameters and composition of the “heads” and “tails” can be separately adjusted over a wide range, the interactivity of the “heads” with the surface and properties of the brushes can be controlled orthogonally, accomplishing surface brushes that cannot be achieved by existing methods.

使用具有交互式“头”的蝌蚪状单链颗粒在活性和惰性表面上稳定地接枝聚合物刷

我们报告了一种“接枝”方法，使用带有交互式“头”的蝌蚪状单链颗粒（TSCP）作为接枝单元，在活性和惰性表面上稳定地接枝高分子量聚合物刷。 TSCP可以通过链内交联二嵌段共聚物的一个嵌段来有效合成； “头”是链内交联的单链颗粒，“尾”是轮廓长度可达微米的线性聚合物链。当接枝到表面时，集成了众多相互作用基团的“头”可以协同与表面的多种弱相互作用，从而使“尾”能够在活性表面和传统上具有挑战性的惰性表面上稳定接枝。由于“头”和“尾”的结构参数和组成可以在大范围内单独调节，因此可以正交控制“头”与画笔表面的交互性和属性，从而实现无法实现的表面画笔。通过现有方法实现。
