20120148829 | POROUS FILMS BY BACKFILLING WITH REACTIVE COMPOUNDS - The invention provides methods for modifying one or more properties of porous thin films. In such methods, a formulation comprising a reactive species is applied to the porous thin film and allowed to crosslink. In some embodiments, the crosslinked network thus formed imparts increased mechanical strength and wear resistance to the porous thin films. | 06-14-2012 |
20130183516 | Porous films by backfilling with reactive compounds - The invention provides methods for modifying one or more properties of porous thin films. In such methods, a formulation comprising a reactive species is applied to the porous thin film and allowed to crosslink. In some embodiments, the crosslinked network thus formed imparts increased mechanical strength and wear resistance to the porous thin films. | 07-18-2013 |
20140079922 | Methods for encapsulating Layer by Layer films and for preparing specialized optical films - 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. | 03-20-2014 |
20140242393 | Methods and materials for functional polyionic species and deposition thereof - 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. | 08-28-2014 |
