LbL build up of the system (CMCS/CS)n as a function of the number of layer pairs deposited by dipping (a) and spraying (b), measured by ellipsometry. CS LMW (blue line) and CS MMW (red line) were used for the assembly of (CMCS/CS)n films. The (CMCS/CS)n film assembly at initial pH of both polyelectrolyte solutions (black line) is indicated only on graph a. The slope of the curves ata for CS LMW (18.6 nm/per layer pair) and CS MMW (11.5 nm/per layer pair; R = 0.998) and atb for CS LMW (16.6 nm/per layer pair; R = 0.999) and CS MMW (9.7 nm/per layer pair; R = 0.998) indicate the thickness per layer pair. Note that the slopes are taken at higher layer numbers after film growth reached a linear regime
