Patent number: 9393589Abstract: The invention provides materials and methods for forming coatings on substrates. The coatings are durable and resistant to damage from environmental, chemical, thermal, and/or radiative sources. In some embodiments, the coatings comprise bilayers of electrostatically charged materials. The bilayers are created by alternately applying solutions comprising water-soluble, electrostatically charged materials. Durability is imparted to the coatings by the formation of crosslinks that are formed within and between layers after deposition of the coatings.Type: GrantFiled: August 15, 2013Date of Patent: July 19, 2016Assignee: Eastman Chemical CompanyInventors: David Olmeijer, J. Wallace Parce, Benjamin Wang, Kevin Krogman

Patent number: 9395475Abstract: Traditional solar control applications rely on thin metal films to reflect EM radiation with wavelengths longer than that of the visible spectrum. Unfortunately such films also block radiation in cellular, GPS, and radio frequency bands. In one aspect, the disclosure provides a selectively-blocking filter that uses one or more optical filters tuned to a specific range(s) of wavelengths (e.g. for blocking IR radiation), while readily transmitting other wavelengths (e.g. both visible light and cellular/GPS signals). The filters can be manufactured on both flexible and rigid substrates.Type: GrantFiled: April 5, 2014Date of Patent: July 19, 2016Assignee: Eastman Chemical CompanyInventors: Kevin Krogman, J. Wallace Parce, Siglinde Schmid, Melissa Fardy, Tom Hood, Steven D. White, Benjamin Wang

Patent number: 9387505Abstract: The disclosure provides materials, apparatuses, and methods for making multilayer coatings with a high degree of efficiency and control. In some aspects, for example, coatings are described having multiple layers of nanoparticles and a polyelectrolyte, wherein the nanoparticles form tightly packed monolayers. The interface between monolayers may include polyelectrolyte material. One or more aspects of such monolayers and interfaces are controllable.Type: GrantFiled: September 12, 2013Date of Patent: July 12, 2016Assignee: Eastman Chemical CompanyInventors: Kevin Krogman, J.

Publication number: 20140242321Abstract: The disclosure provides methods and materials for preparing bridging films. In one aspect, the bridging films are non-porous and are suitable for protecting adjacent porous films. For example, the bridging films contact a porous film and protect the porous film from transfer of gases and/or liquids into the pores of the porous film. In another example, bridging films protect the porous film from abrasion.Type: ApplicationFiled: May 2, 2014Publication date: August 28, 2014Applicant: Svana Nanotechnologies, Inc.Inventors: Siglinde Schmid, Melissa Fardy, J.

Publication number: 20140079922Abstract: Durable coatings and methods for producing the same are provided, where the coatings may include porous coatings encapsulated with a hardening solution that permeates into the porous structure of the film prior to curing. Curing of the hardening solution within the film provides for a durable coating having sufficient durability for use in many different applications, such as optical applications. Any convenient porous coatings may be used in the subject methods. Also provided are methods for forming a coating formulation, where the formulation includes porous coating particles dispersed in a carrier and the porous coating particles may be optionally encapsulated with a hardening solution prior to dispersion.Type: ApplicationFiled: September 16, 2013Publication date: March 20, 2014Applicant: Svaya Nanotechnologies, IncInventors: Benjamin Wang, David Olmeijer, Siglinde Schmid, Melissa Fardy, J.
