A Reversed Duckweed polymeric LB film was fabricated by a new kind of amphiphilic polymer which was composed of hexanediamine- epichlorohydrin hydrophilic network and hydrophobic chains containing p-nitroazobenzene groups. Reversible optical birefringence and dichroism have been demonstrated in this polymeric LB film, and this reversible birefringence and dichroism can be cycled many times without...
The structure of a self-organized polymer film prepared by slow evaporation of organic solvents is studied by atomic force microscopy, and compared with that of polymer film prepared by natural evaporation of organic solvents. AFM studies clearly indicates that there exists a self-organizing process of alkyl chains resulting in the partial interdigitated layer structure under the condition of slow...
