摘要:
A hybrid bioelectrical interface (HBI) device can be an implantable device comprising an abiotic component operable to transmit charge via electrons or ions; a biological component interfacing with the neural tissue, the biological component being sourced from biologic, biologically-derived, or bio-functionalized material; and a conjugated polymer component that together provide a means to chronically interface living neural tissue with electronic devices for extended durations (e.g. greater than 10 years). In some embodiments, conjugated polymers provide a functional electrical interface for charge transfer and signal transduction between the nervous system and an electronic device (e.g. robotic prosthetic limb, retinal implant, microchip).

摘要:
Substituted 3,4-propylenedioxythiophene monomers may be prepared by reacting 3-allyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine or 3,3-diallyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine with a thiol having a hydrocarbyl moiety optionally containing one or more heteroatom-containing functional groups under radical addition conditions under radical addition conditions. Such monomers may be used in homo- or copolymerization processes to obtain thiophene-type polymers containing substituents (which may bear functional groups such as silane, thiol, hydroxyl, carboxylic acid, amine, sugar groups, polyoxyalkylene, and the like). Crosslinkers useful for introducing crosslinking into thiophene-type polymers may be prepared by reacting 3-allyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine with a compound having two or more thiol groups under radical addition conditions.
摘要:
An electroconductive carboxylic acid functionalized monomer corresponding to Formula (I), wherein A represents a hydrogen or a carboxyl group. Polymerized monomers of Formula (I) conjugated with a biomolecule result in conjugated PEDOT polymers of Formula (III) wherein A is a hydrogen or a carboxylic acid group and B is a biomolecule selected from the group consisting of a peptide, a protein, a lipid, a carbohydrate and a polynucleotide. The biomolecule conjugated polymers can be disposed onto an electrically conductive substrate wherein the substrate has a first layer of PEDOT polymerized on a surface of the substrate and a second layer of biomolecule conjugated PEDOT polymer of Formula (III) polymerized on the first layer of PEDOT. The first and second layers form a charge transport material in electrical communication with the conductive substrate. The electrically conductive substrate further comprises a dopant.
摘要:
A fire-resistant retroreflective structure having an array of rigid retroreflective elements and a method for making the structure are disclosed. The retroreflective structure is formed of an array of rigid retroreflective elements having a first side and a second side. A transparent polymeric film is attached to the first side of the array of rigid retroreflective elements. A transparent fire-resistant outerlayer is attached to the transparent polymeric film. A flame-retardant layer is placed proximate to the second side of the array of rigid retroreflective elements. A fire-resistant polymer underlayer is attached to the flame-retardant layer. The five resistant polymer underlayer can be bonded to the transparent polymeric film through the array of rigid retroreflective elements and the flame-retardant layer.
