  • Publication number: 20210395463
    Abstract: In an aspect, a method of synthesizing a graft copolymer comprises the steps of: copolymerizing a first macromonomer and a first reactive diluent; wherein said first macromonomer comprises a first backbone precursor directly or indirectly covalently linked to a first polymer side chain group; wherein said reactive diluent is provided in the presence of the first macromonomer at an amount selected so as to result in formation said graft copolymer having a first backbone incorporating said diluent and said first macromonomer in a first polymer block characterized by a preselected first graft density or a preselected first graft distribution of said first macromonomer. In some embodiments of this aspect, said preselected first graft density is any value selected from the range of 0.05 to 0.75. In some methods, the composition and amount of said diluent is selected to provide both a first preselected first graft density and a first preselected first graft distribution.

  • Patent number: 10608280
    Abstract: Provided herein are copolymer electrolytes and electrocatalyst platforms, including brush block copolymers, triblock brush copolymers and pentablock brush copolymers. The copolymers described have beneficial chemical, physical and electrical properties including high ionic conductivity and mechanical strength. In embodiments, for example, the provided copolymer electrolytes and electrocatalyst platforms are doped with lithium salts or mixed with ionic liquids to form ion gels. In some embodiments, the copolymers provided herein self-assemble into physically cross-linked polymer networks with additional useful properties. The provided copolymers have low dispersity in the polymer side chains and do not require post-polymerization modifications.

  • Patent number: 10153513
    Abstract: Provided herein is a class of copolymers, including triblock brush copolymers having specific block configurations, for example, ABC triblock brush copolymers and ABA triblock brush copolymers. In an embodiment, for example, copolymers of the invention incorporate various polymer side chain groups which contribute beneficial physical, chemical, or electronic properties such as increased mechanical or elastic strength, improved ionic or electric conductivity. In some embodiments, the provided copolymers exhibit advantageous steric properties allowing for rapid self-assembly into a variety of morphologies that are substantially different than non-brush, block copolymers.

  • Patent number: 9528683
    Abstract: A luminaire is provided, that includes a housing and a plurality of solid state light sources connected thereto. The housing has a top side, two lateral sides, a protrusion in the top side, and two light source mounting surfaces. The top side is diffusely reflecting and has opposing lateral edges and a center. The lateral sides are specularly reflecting and extend generally downward from the opposing lateral edges of the top side. Each has a respective bottom edge. The light source mounting surfaces extend laterally inward from the respective bottom edges. The plurality of solid state light sources is disposed along the pair of light source mounting surfaces proximate the pair of specularly reflecting lateral sides. These emit light, which travels upward to the top side and is also specularly reflected by the lateral sides toward the top side. The top side diffusely reflects the light out of the luminaire.
