Spin-Assembled Layer-by-layer Films of Weakly Charged Polyelectrolyte Multilayer |
| 초록 |
We investigate the effect of film deposition methods on the film properties of layer-by-layer assembled polyelectrolyte multilayers(PEM). Multilayered structures of linear polyethylenimine and poly(acrylic acid) are prepared by using conventional dipping-based assembly(DA) as well as spin-assisted assembly(SA). While the PE interpenetration by the diffusion motion of LPEI is allowed in DA, an instantaneously and kinetically frozen phase of the film deposition is obtainable from SA. Being kept from the interdiffusion of LPEI, a stratified internal structure is expected in the SA, which is contrasted to the intermixed phase in the DA. The ability to control the inner structure of the film enables us to manipulate the properties or chemical activity of the functionalized thin films. We also demonstrate that the control over the strength of PE interdiffusion on a top surface can be utilized for a quantitative manipulation on the degree of macromolecular self-assembly of nanomaterials. |
