摘要
To prepare layer-by-layer（LbL） multilayers in time-efficient manners by the dipping method is highly ap- pealing. However, the fast LbL assembly produces multilayers with high surface roughness. In our attempt to smooth the surface morphologies of LbL multilayers obtained by fast assembly（5 s dipping）, we studied the influence of the assembly conditions on the surface morphologies. The study shows that by properly adjusting the assembly condi- tions, such as washing duration, water annealing period, and drying with nitrogen flow, LbL multilayers with en- hanced surface smoothness could be obtained through fast LbL assembly.
