Abstract |
Construction of layer-by-layer (LbL) self-assembled multilayers is fundamental to various research fields.
But most conventional processes for LbL are time consuming, which restricts its further applications.
There has been a general demand for shortening the construction time without affecting the multilayer
structures. High-gravity (HG) technique is a well-established chemical engineering process which can
strongly intensify mass and heat transfer. In this study, we introduced the HG technique into construction
of multilayers through LbL self-assembly concerned with polymer micelles as building blocks. By
using a model system of poly(diallyldimethyl ammonium chloride) (PDDA)/polystyrene-poly(acrylic
acid) (PS-PAA) polymer micelle multilayers, the LbL process was examined under both conventional dipping
conditions and a HG field. Ultraviolet–visible spectra and atomic force microscopy results showed
that the time for LbL under a HG field has been shortened 6 times compared with dippin
