Abstract:
Provided is a resin-metal composite material that ensures high adhesion between a resin material and a metal material. Additionally provided is a tire that achieves high durability by using the resin-metal composite material. The resin-metal composite material includes a metal material and a resin material that coats at least a part of the surface of the metal material. The resin material includes, as a main component, a thermoplastic resin having a polar group. The surface of the metal material is treated with a buffer solution having a pH of from 5 to 7.2, and an abundance ratio of copper to a total amount of copper and zinc (Cu/(Cu + Zn) × 100) in the surface of the metal material is from 55 to 95% by mass. The tire includes a circular tire frame formed of a resin material and a reinforcing layer composed of a reinforcing member wound around an outer circumference of the tire frame, in which the reinforcing member includes the resin-metal composite material.
Abstract:
A dye-sensitized solar cell of high power generation performance including a semiconductor film that can be formed at relatively low temperature is provided. A titanium oxide paste is applied onto transparent conductive film (2), and dried to thereby form a titanium oxide layer. Aqueous solution of peroxotitanic acid (11) is dropped on the titanium oxide layer, and heated. At this stage, the aqueous solution of peroxotitanic acid penetrates in part where any titanium oxide particles (10) are not adsorbed on the transparent conductive film (2), and this aqueous solution of peroxotitanic acid (11) reacts so as to form titanium oxide (11A). By virtue of the formation of the titanium oxide (11A) in interstices (s,t) between the titanium oxide particles (10), the linkages of titanium oxide particles (10) can be intensified to thereby realize an enhancement of power generation efficiency.
Abstract:
There are disclosed a thermoplastic elastomer composition which comprises (a) a hydrogenated block copolymer obtained by hydrogenating the block copolymer comprising at least one polymer block composed principally of a vinylic aromatic compound and at least one polymer block composed principally of a conjugated diene compound; (b) a non-aromatic base softening agent having a kinematic viscosity at 40 DEG C of at least 100 mm /sec; and (c) propylene homopolymer and/or propylene copolymer comprising propylene as a principal component which is obtained through polymerization by using a metallocene catalyst, which is free from a lubricant, which has been heat treated, or which has a MFR (melt flow rate) in a specific range; a gasket material which comprises the above thermoplastic elastomer composition and is particularly suited for use in hard disc units because of its excellent sealing properties and its capability of preventing gas generation; a method for injection molding the above composition; an external anti-sticking agent for a thermoplastic elastomer or rubber which comprises fine particulates of ultrahigh molecular weight polyethylene having an average particle diameter in a specific range, and which is minimized in hygroscopicity, oil absorptivity and volatility, and has high heat resistance and anti-stickiness; and rubber and/or a thermoplastic elastomer which is incorporated with the above external anti-sticking agent and imparted with anti-stickiness.
Abstract:
The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(alkenyl benzene-co-maleimide) polymer with a maleated polyalkylene and a maleated hydrogenated block copolymer and an alkyl diamine grafting agent under substantially dry conditions sufficient to form a hydrogenated block copolymer-polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product; and, dispersing the hydrogenated block copolymer-polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product with an extender oil sufficient to form the gel. The present invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.
Abstract:
An air bag is made with a bag body of elastomeric film (15) having a high breaking extension, and a shape-retaining member (14) which controls the shape taken by the bag when inflated. The shape-retaining member is attached over part of the surface of the bag body, and is a composite of (a) elastic fibres or threads and (b) high-modulus fibres selected from aramid (R. T. M) fibres, aromatic polyester fibres and ultra-high molecular weight polyethylene. A composite fibre may be used having the high modulus material wound round an elastic core and it may be formed, eg woven, into a tape. Alternatively a fabric having separate areas of the respective fibres may be heat-laminated over the bag body.
