    摘要: Embodiments of the invention relate to energy storage devices, e.g., capacitors and batteries, that may include a composite article of elongated conductive structures embedded in a polymer matrix. In some embodiments, a liquid containing ionic species may be dispersed within the polymer matrix of the article. The liquid may contact the elongated conductive structures within the polymer matrix. When the composite article is used as an energy storage device, the large surface area at the interface between the elongated conductive structures and the liquid can provide high energy storage. Embodiments of the invention enable storing energy using a composite article that exhibits both high and low temperature stability, high cyclic repeatability, and mechanical flexibility. The composite article can also be non-toxic, biocompatible and environmentally friendly. Thus, the composite article may be useful for a variety of energy storage applications, such as in the automotive, RFID, MEMS and medical fields.

    摘要: A self-healing polymer additive includes diene (e.g. butadiene, cyclohexadiene, pentadiene, tetrahydrofuron or their derivatives) and dienophile (e.g. maleic anhydride, maleamide, conjugated carbonyls or their derivatives etc.). One polymer includes tetrahydrofuron and maleimide. Furfurylamine 12 (1-10 gm) is diluted in acetone. Under an inert atmosphere an equivalent amount of granular maleic acid is added slowly, and the reaction is allowed to take place. Resulting maleamic acid precipitates. The maleamic acid product is separated, dried and purified by re-crystallization. The maleamic (1-5 gm) acid is dissolved in acetic anhydride along with a catalytic amount of sodium acetate. The resulting solution is heated for a few hours in 80-120° C. The precipitated final product is separated, purified and dried in a vacuum. The self-healing polymer is dissolved in a solvent, and self-healing molecules are cross linked and are mixed with a polymer matric for various applications such as coatings and structural materials.
