使用基于静电的超级喷墨打印机，我们报告了聚电解质大分子引发剂的高分辨率沉积和随后使用SI-ARGET-ATRP的聚合物刷子的生长。我们继续通过添加相同电荷的聚电解质均聚物或通过仔细控制离子强度，首次展示了亚微米图形现象。因此，据报道，聚合物刷子的图案化达到了约300纳米。我们提出了一个可能的机理模型，并考虑如何将其应用于其他基于聚电解质的系统，作为亚微米图案化的一般方法。
Using an electrostatic-based super inkjet printer we report the high-resolution deposition of polyelectrolyte macroinitiators and subsequent polymer brush growth using SI-ARGET-ATRP. We go on to demonstrate for the first time a submicron patterning phenomenon through the addition of either a like charged polyelectrolyte homopolymer or through careful control of ionic strength. As a result patterning of polymer brushes down to ca. 300 nm is reported. We present a possible mechanistic model and consider how this may be applied to other polyelectrolyte-based systems as a general method for submicron patterning.
