Publication number: 20130034653Abstract: Methods and compositions for forming durable porous low refractive index coatings on substrates are provided. In one embodiment, a method of forming a porous coating on a substrate is provided. The method comprises coating a substrate with a sol-formulation comprising a silane-based binder, silica-based nanoparticles, and an inter-particle interaction modifier for regulating interactions between the silica-based nanoparticles and annealing the coated substrate. Porous coatings formed according to the embodiments described herein demonstrate good optical properties (e.g., a low refractive index) while maintaining good mechanical durability due to the presence of the inter-particle interaction modifier. The inter-particle interaction modifier increases the strength of the particle network countering capillary forces produced during drying to maintain the porosity structure.Type: ApplicationFiled: August 1, 2011Publication date: February 7, 2013Applicant: INTERMOLECULAR, INC.Inventors: Nitin Kumar, Nikhil D.

Publication number: 20130034722Abstract: Durable porous low refractive index coatings, methods and compositions for forming the porous low refractive index coatings are provided. The method comprises coating a substrate with a sol formulation comprising a silane-based binder having one or more reactive groups and silica based nanoparticles and annealing the coated substrate. The silane-based binder comprises from about 30 wt. % to about 70 wt. % ash contribution in the total ash content of the sol formulation. Porous coatings formed according to the embodiments described herein demonstrate good optical properties (e.g., a low refractive index) while maintaining good mechanical durability due to the presence of a high amount of binder and a closed pore structure.Type: ApplicationFiled: August 1, 2011Publication date: February 7, 2013Applicant: INTERMOLECULAR, INC.Inventors: Nikhil D.
