A facile approach and strategy towards binary composition, two-dimensional (2D) patterned surfaces of conducting polymer periodic arrays together with thiol SAMs  and electropolymerized macroinitiators is described. The method involved a Langmuir Blodgett (LB)-like deposition of latex microsphere particles, electropolymerization by CV technique, and self-assembly of an amphiphile. The LB-like technique enabled the monolayer deposition of different sizes of polystyrene (PS) particles in hexagonal packing arrangement on planar substrates.  Combining the LB-like method with CV electropolymerization is advantageous as it provides deposition control of a polymer interconnected network, controlled composition ratio of polymer and SAMs, and control of 2D size and spacing of the spherical void pattern.. The dual patterned surface provided a good imaging contrast as observed by AFM. Complimentary analyses such as XPS, ATR IR, UV-Vis spectroscopy, and static contact angle measurements were used to characterize the formation of the patterned surface. The versatility of the method enables the potential for  making various types of quantitative binary compositions and patterned surfaces using different combinations of conducting polymer or functional SAMs, which can be extended to polymer brushes.
