Supramolecular structure of acrylic acid, and li-ion battery using same

As a method for improving the service life of a li-ion battery, a supramolecular structure of acrylic acid which is a polymer formed by aggregating m number (an aggregation degree of m) of single chains each including n number (a polymerization degree of n) of acrylic acid monomers connected to each other, and has a constricted (narrowing) channel structure in which the single chains are arranged in a circle on the xy plane, a main chain is oriented along the direction of a central axis in the z direction, and a carboxyl group in a side chain is oriented along a direction perpendicular to the central axis in the z direction is used. As a result of an interaction between this constricted channel structure and an organic solvent molecule, the organic solvent molecule is captured inside the constricted channel structure, and the diffusion of the organic solvent molecule is inhibited..

Method for producing contact lenses with durable lubricious coatings thereon

The invention is related to a method for producing silicone hydrogel contact lenses with having a stable coating thereon. A method of the invention comprises a water-based coating process (step) for forming a relatively-stable base coating of a homo- or copolymer of acrylic acid or c1-c3 alkylacrylic acid onto a silicone hydrogel contact lens made from a lens formulation comprising from about 35% to about 60% by weight of n-vinylpyrrolidone..
