摘要： Articles having a complex geometric configuration have hydrophilicity imparted to at least a portion of surfaces of the articles while substantially retaining the complex geometric configuration. The hydrophilicity is imparted by an extremely thin, self-interlocking shell of tactic, hydrophilic poly(vinyl alcohol) enveloping the surfaces. A tactic poly(vinyl alcohol) precursor applied to surfaces of the supporting structure is reacted in situ on the surfaces with a hydrolysis reagent to prepare the tactic, hydrophilic poly(vinyl alcohol) shell. The article having the hydrophilic shell is highly resistant to solvent washout. Hydrophilicity and hydrophobicity can be reversibly provided on regio-specific surfaces of the article. Articles in the form of membranes useful as filters, residue barriers for electroplating devices, separators for electrochemical cells, and drug delivery device components are also described. Membranes to form permanent and undistorted images, and methods of preparing such images from image-forming substances in receptive media are also provided. Hydrophilic porous supporting structures loaded with an enzyme system which catalyzes a reaction of a substrate, oxygen, and if necessary, water or moisture to consume oxygen are also described for oxygen scavenging in packages containing oxygen sensitive products.

摘要： PROBLEM TO BE SOLVED: To impart corrosion resistance, lubricity, wear resistance and electrical insulating property by impregnating a surface treating agent containing a polymerizable fluorine-containing organic monomer into the porous surface of a formed body and polymerizing the monomer to seal the micropores in the porous surface. SOLUTION: The porous surface to be surface-treated is most preferably an anodic oxide film of Al formed on the surface of a formed body comprising Al or Al alloy. The monomer contained in the surface treating agent is preferably a fluorine-containing (meth)acrylic ester monomer. The surface treating agent preferably contains the monomer, a solvent and a polymerization initiator. Vacuum impregnation is preferable for the impregnation of the surface treating agent into the porous surface. The polymerization of the monomer after the impregnation is preferably carried out in a liquid phase containing a polymerization accelerator preferably containing a hydrazine compound and a fluorine- containing phenolic compound and/or a fluorine-containing carboxylic acid compound.

摘要： PROBLEM TO BE SOLVED: To prevent peeling even under repetitive thermal stress and to retain various functions by disposing a functional coating layer surface-coated with a cured body of a thermosetting resin mixed with a fluororesin. SOLUTION: A fluid prepared by dispersing fluororesin powder in a thermosetting resin is applied to the surface of a graphite material to form a coating layer having functions such as water repellency as a monolayer. When a thermosetting resin having a great affinity for the graphite material is used, the adhesion of the coating layer to the graphite material can be enhanced, the coating layer can be made thinner and the impairment of functions such as wear resistance and self-lubricity peculiar to the graphite material can be inhibited. Since the coating layer penetrates into the pores in the surface of the graphite material and coats the surface, the penetration of water and impurities into the base material can also be prevented. The fluororesin content of the thermosetting resin is preferably 30-80 mass %.

摘要： PROBLEM TO BE SOLVED: To provide a superconductor capable of securing high trapped magnetic field strength and maintaining the performance over a long period without being affected by internal or external force such as electromagnetic force or thermal strain, or corrosive environment and to provide at production process for the superconductor. SOLUTION: This superconductor consists of an oxide superconducting bulky body (such as rare earth element-based copper oxide superconducting bulky body) having a resin-impregnated layer, as illustrated in the figure, wherein optionally, an adequate amount of Ag may be added to the bulky body. The superconductor is formed by bringing an oxide superconducting bulky body maintained in a reduced-pressure atmosphere into contact with a liquid resin, to impregnate the bulky body with the liquid resin.
