In this communication, we demonstrate that dopamine is able to undergo a polymerisation process in (PLL-HA)n polyelectrolyte multilayer films, and that this polymerisation is of the same nature as in solution at pH 8.5. This polymerisation changes the chemical composition and decreases the mobility of the PLL chains in the film, and ultimately allows the easy detachment of the film as free-standing membranes with 0.1 M HCl solutions.
在本通讯中，我们证明多巴胺能够在（PLL-HA）n聚电解质多层膜中发生聚合过程，并且这种聚合与在pH 8.5的溶液中的聚合性质相同。这种聚合改变了膜的化学组成并降低了PLL链在膜中的迁移率，最终使得膜能够在0.1 M盐酸溶液中轻松地以独立膜的形式分离出来。
