| 제목 | Fabrication of Polyelectrolyte Multilayer Films Comprising Nanoblended Layers |
| 초록 | Over the last decade the versatile layer-by-layer (LbL) assembly method has been widely utilized for the preparation of ultrathin polyelectrolyte (PE) films that show promise as light-emitting diodes, as electrochromic, membrane and bioactive thin films, for selective area patterning, for particle surface modification and the formation of capsular colloids. Such films are typically prepared by the consecutive deposition of oppositely charged PEs from single-component solutions onto a solid support. Few studies have examined the formation of thin films from solutions containing two or more components in each adsorption solution, and in studies that have, the species employed have been of opposite charge, thus complexing in solution prior to adsorption. Herein, we report the formation of multilayer films comprising nanoblended (i.e., mixed) layers of both weak (poly(acrylic acid), PAA) and strong (poly(styrene sulfonate), PSS) polyanions, alternately deposited with the polycation (poly(allylamine hydrochloride), PAH). This weak/strong PE combination was chosen because of the recent interest generated by multilayer films containing weak PE, which is largely attributed to their pH-dependent characteristic. We demonstrate that blended layers can be used to tailor film composition and thickness (without the addition of salt), as well as surface morphology and pH stability. |
