Abstract

The selective adsorption of carbon nanotubes (CNTs) on a pH-reversible PDMAEMA patterned gold surface is presented. In acidic conditions, a selective CNTs adsorption onto the polymer brushes is obtained due to ammonium-π interactions. The reversible behavior was shown by successive treatments in both alkaline and acidic solutions with CNTs.

摘要

本文展示了在 pH 值可逆 PDMAEMA 图案化金表面上对碳纳米管 (CNTs) 的选择性吸附。在酸性条件下，由于铵-π 相互作用，CNTs 选择性地吸附在聚合物刷上。通过在碱性和酸性溶液中连续处理，可以观察到这种可逆行为。
