1. A method for replicating at least one textured surface, said method comprising the following steps:

  • providing at least one master having at least one textured surface with microtexture cones, wherein said microtextured cones of said at least one master includes nanoscale features on surfaces of said microtexture cones of said at least one master;

    providing at least one substrate;

    providing at least one replicating material, wherein said at least one replicating material is in communication with said at least one substrate;

    placing said at least one textured surface of said at least one master in contact with said at least one replicating material;

    applying an embossing force to the combination of said at least one master, said at least one replicating material, and said at least one substrate;

    heating at least one of said at least one master, said at least one replicating material, and said at least one substrate;

    reducing or eliminating said heating;

    removing said embossing force;

    separating said at least one master from said at least one replicating material to provide a replica of said at least one textured surface with microtexture cones of said at least one master, wherein said microtexture cones of said replica includes nanoscale features on surfaces of said microtexture cones of said replica, wherein said nanoscale features of said replica are the result of correctly replicating said at least one master;

    wherein said separating step directly provides said replica without any additional processing steps to accomplish said replica, and wherein said surface of said replica is superhydrophobic.
