Abstract
Free-standing flexible nanomembrane is a key soft material for the development of permselective membrane, microactuator and drug delivery etc. Here, we present fabrication of robust free-standing ultrathin films consisting of amphiphilic alkylacrylamide polymers (pDDA) by Langmuir-Blodgett (LB) technique. The structural stabilization was achieved through a two-dimensional hydrogen bonding network between amide groups and molecular interaction between alkyl chains. It was confirmed that the ultrathin films had highly ordered structure with nanoscale periodicity and formed bilayer structure (thickness: 3.3 nm) analogous to biomembrane structure using atomic force microscopy (AFM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) measurements.
