Abstract
We report on the preparation and characterization of multidimensional nano-objects nanoassembly in film surface coatings. 2D reduced graphene oxide (rGO) sheets are assembled with OD block copolymer micelles (BCM)s through electrostatic layer-by-layer assembly. The BCM/rGO paired nanoassembly surface coatings were formed via sequential adsorption of polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) aqueous solutionsand modified rGO sheets with carboxylic acids groups, and the process was monitored by UV-vis spectroscopy. SEM and AFM were used to Investigate surface morphology and the growth of multilayer coatings as a function of the number of bilayers. In addition, encapsulated hydrophobic fluorescence organic dyes were imaged via confocal microscopy. Evenly distributed BCMs on coatings were successfully obtained. We expect that this demonstration offers a new route to introduce nanoassembly of two different dimensional-shaped nano-objects in surface coatings for many industrial uses and makes building more complex, functional multicomponent, and multidimensional structures possible for use in nano-objects incorporated various multicoating applications.
