Novel coatings are disclosed prepared from electropolymerization of electropolymerizable monomers-analyte complexes onto a conducting layer or non-conducting of a substrate, where the analyte is removed by electrochemically mediated washing permitting linear molecular sensing of the analyte over a wide concentration range. The coating may also include templating particles deposited on the electrode substrate prior to electropolymerization, where the particles can be removed to form a submicron structured coating. Methods for making and using the coatings are also disclosed.

Sensors and separation based on molecular recognition via electropolymerization and colloidal layer templates

The disclosed subject matter provides a filter that is modified by a polymer-carbon based nanomaterial nanocomposite intended to significantly enhance the performance of filtration, separation, and remediation of a broad variety of chemicals, heavy metal ions, organic matters, and living organisms. Polymeric materials, such as but not limited to poly-N-vinyl carbazole (PVK), are combined with (1) graphene (G) and/or graphene-like materials based nanomaterials and (2) graphene oxide (GO) chemically modified with a chelating agent such as but not limited to EDTA. The nanocomposite is homogenously deposited on the surface of the membrane.

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.

Nano-composites include a graphite material such as nanotubes or graphene sheets and a partial or complete coating of a polymer including sufficient &#x3c0;-conjugated moieties to interact with surfaces of the graphite material. The polymers may also include electropolymerizable or oxidatively polymerizable moieties so the films may be crosslinked. The films may be used to form layers on substrates or patterned layers on substrates.
