Fabrication and structure of "polymer nanosphere multilayered organization"
We constructed a multiparticle layered organization of aromatic polyamides with rigid main chains and flexible side chains by the Langmuir-Blodgett (LB) technique, which resulted in a highly regular arrangement along the c-axis. The particle arrangement was estimated by performing out-of-plane X-ray diffraction (XRD) analysis and atomic force microscopic (AFM) observation. The results suggest that a doubleparticle layered structure (Y-type) is formed by the LB technique, forming amphiphilic particles at the air/ water interface. Copolymers with highly hydrophobic carbazole contents and both hydrogenated and fluorinated side-chains also formed a single-particle layer at the air/water interface and exhibited multiparticle layers by a LB technique. Therefore, it is possible to control the formation of single- and double-particle layered structure using these techniques. Further, it was found that multiparticle layered organization of polymer nanospheres and polymer nanosheets could be formed simultaneously with the same component material. (C) 2013 Elsevier Inc.
