Well-defined cylindrical polymer brushes with hydrophilic poly(acrylic acid) core and hydro-phobic poly(n-butylacrylate) or polystyrene shell can be used as cylindrical templates and nanoreactors for the fabrication of various inorganic nanowires, due to the coordination ability of poly(acrylic acid) with a number of different metal ions. The size control of nanowires can be easily achieved via controlled synthesis of the polymer brushes with different lengths and diameters. The shell of the polymer brushes protects the fabricated nanowires from agglomeration. In addition, the solubility of the hybrid materials can be controlled by the polymer shell. Depending on the material and the size of nanowires, unique properties (such as magnetic, electric, semiconducting, catalytic properties) of the hybrids can be obtained for various applications.

具有亲水性聚丙烯酸核和疏水性聚丙烯酸正丁酯或聚苯乙烯壳的轮廓分明的圆柱形聚合物刷可以用作圆柱形模板和纳米反应器，用于制备各种无机纳米线，这是由于聚丙烯酸与许多不同金属离子的配位能力。纳米线的尺寸控制可以通过控制合成具有不同长度和直径的聚合物刷来容易地实现。聚合物刷的外壳保护所制造的纳米线免于团聚。此外，杂化材料的溶解度可以通过聚合物壳来控制。根据纳米线的材料和尺寸，可以获得用于各种应用的杂化物的独特性质（例如磁性、电学、半导体、催化性质）。
