抄録

We constructed two-dimensional integrated single particle layer on the water surface of aromatic polyamides (poly-(N-alkylated benzamides) abbrev. PABAn n: carbon number of side-chains) having both a rigid main-chain and a flexible side-chain with different lengths. Further, the build-up particle layers with highly regular arrangement along the c-axis are formed by Langmuir-Blodgett (LB) method. Molecular orientation and surface morphology of organized particle films of PABAn were investigated by performing surface pressure-area (π-A) isotherm, in-plane and out-of plane X-ray diffraction (XRD), and atomic force microscopy (AFM) measurements. These single particle layers of several aromatic polyamides on the water surface were highly condensed at 15 ℃. Results of out-of plane XRD measurement of multi-particle layers showed that the PABA, particle layers showed large periodicities of 50-60 Å at 15 ℃. From these experimental findings, it was concluded that the polymer synthesis method employed in the present study can be directly used to control their surface morphologies, behavior of two-dimensional integration and multi-particle layer formation.
