A manufacturing method of a porous carbon composite material includes the following steps. A polymer template is provided, the polymer template includes a polymer compound, and the polymer template has a plurality of pores. A coating step is performed, wherein a metal compound is coated on the polymer template to form a transition intermediate. A heating step is performed, wherein the transition intermediate is heated to transform the polymer template to a carbon template and transform the metal compound to a coating layer, and a porous carbon composite material is obtained.

Certain applicator liquids and method of making the applicator liquids are described. The applicator liquids can be used to form nanotube films or fabrics of controlled properties. An applicator liquid for preparation of a nanotube film or fabric includes a controlled concentration of nanotubes dispersed in a liquid medium containing water. The controlled concentration is sufficient to form a nanotube fabric or film of preselected density and uniformity.

This invention pertains to inkjet printing on fabric and to a pretreatment solution for the fabric that allows high quality printing thereon. The aqueous pretreatment solution/emulsion comprises a nonionic latex polymer and a multivalent cationic salt.
摘要:
In a preferred embodiment, the present process involves subjecting a fabric having splittable conjugate yarns both to an acidic treatment and to a basic treatment, each of which erodes a portion of the components of the conjugate yarns. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The basic treatment has a similar effect on the polyester element of the conjugate filament, making it more hydrophilic. The at least partial removal of the polyamide component, coupled with the increased hydrophilicity of the polyester component, results in a fabric having enhanced absorptive properties. In an alternate embodiment, treatments with only acid or only basic solution may be employed.
摘要:
This invention relates to an improved process for providing fibrous polyamide materials and wool materials with stain resistance and superior lightfastness that are more durable against alkaline washing. This is accomplished by treating the materials with an aqueous solution comprising a combination of a partially sulfonated novolak resin, methacrylic polymer and a soluble aluminum compound or a combination of a partially sulfonated novolak resin and a soluble aluminum compound.
摘要:
The present invention is directed to a method for lactonizing a vinyl copolymer containing a vinyl monomer having nitrile groups and a monomer having hydroxyl groups and/or a monomer capable of forming hydroxyl groups or an article shaped from said copolymer by treating the same in an acid medium so that lactone rings are formed in said copolymer or shaped article, characterized by adding a transition metal ion such as zinc or copper to said acid medium. By the addition of the transition metal in the acid medium, the lactonizing reaction is greatly accelerated.
