Types of electrodeposited polymer coatings with reversible wettability and electro-optical properties

摘要

Novel coatings are disclosed prepared by electropolymerization of non-fluorinated conducting pre-grafted hydrophobic electropolymerizable monomers onto a conducting layer of a substrate, where the electropolymerized coating exhibit both unique reversible wettability and electro-optical properties. The coating may also include one or more layers of polymer particles upon which the non-fluorinated conducting pre-grafted hydrophobic electropolymerizable monomers are polymerized imparting a submicron structure to the coating. Methods for making and using the coatings are also disclosed.

1. A method for forming non-fluorinated conducting polymer coatings on a substrate comprising:
forming a conducting layer on a surface of a substrate, and electrodepositing monomers of the general formula:
A-RZ  (I)to form a non-fluorinated conducting polymer coating on the conducting layer to form a coated substrate, and where A is an anodic electropolymerizable group and is 2,5-di(thiophen-2-yl)thiophen-3-yl, R is an alkenyl group having between 1 and about 20 carbon atoms, where one or more of the carbon atoms may be replaced by oxygen atoms, amino groups, amide groups, ester groups, or mixtures thereof, and Z is an end group selected from the group consisting of COOH, COOR1, and mixtures thereof, R1 is a carbyl group having between 1 and about 10 carbon atoms and where the coating has controllable properties by applying an electric potential across the coating, where the properties include redox chemical, wettability and electrochromic or electro-optical properties.
