he effect of poly-l-lysine structure on the pH response of polygalacturonic cid-based multilayers arta Westwood

Abstract

The effect of poly-l-lysine (PLL) molecular weight and structure on pH stability of polygalacturonic acid (PGaLA)-based multilayer films is studied over a pH cycle 7.0–1.6–7.0. The multilayer assembled with the lowest molecular weight PLL (1 kDa) showed the largest pH response. Only 12% of the mass remained and a preferential loss of PLL was observed… (More)
