Interfacial structures/pattern, especially with small-scale dimensions, are important to the chemistry of materials in determining the optical, electrical, mechanical, or other physical properties of novel materials. Polymers are often used for surface patterning. The diversity, the relatively low cost, the convenient mechanical properties and the compatibility with most patterning techniques render polymers attractive candidates for patterning processes. The objective is to demonstrate through Finite Element Analysis, the utility of the Electro-hydrodynamic Induced Patterning (EHDIP) for patterning nano scale morphology.
