The fabrication of free-standing ultrathin polymer films with reactive polymer nanosheets organized with gold nanoparticles was presented. the photocrosslinkable polymer nanosheets were hybridized with gold nanoparticles which enabled the visualization of the ultrathin film more easily because of its strong extinction coefficient. The self-assembled hydrogen-bonding network between amide groups provides densely packed and stable polymer monolayer formation and multilayer deposition using the Lnagmiur-Blodgett (LB) method. Multilayered polymer nanosheets were robustly immobilized onto the substrate by using the photopolymerization of methacryloyl group incorporated into the polymer nanosheets by deep UV irradiation. The immobilized nanosheets have great mechanical and chemical stability because of a 3-D photocrosslinking network in polymer nanosheets.
