Self-cleaning coatings

Номер: US20120010314A1
Принадлежит: University of Western Ontario

The present invention provides two methods for synthesizing novel titania-polyurethane (nTiO 2 -PU) nanocomposites for self-cleaning coatings, one a polymer functionalization method (“grafting to”) and the other, a monomer functionalization method (“grafting from”). Here, 2,2 bis(hydroxymethyl) propionic acid (HMPA) was used as the coordination agent, which was reacted with n-TiO 2 (50:50 anatase/rutile) to form nTiO 2 -HMPA, then polymerized in the monomer functionalization method. In the polymer functionalization method, HMPA was reacted with a pre-polymer to form the PU, and then subsequently reacted with n-TiO 2 to form the polymer nanocomposite. The photocatalytic cleanability of the nanocomposites was investigated when exposed to ultraviolet radiation using additional unreacted HMPA or stearic acid as the model “dirt” compounds. Nanocomposites prepared using both strategies showed similar self-cleaning behavior, although the monomer technique gave less substrate degradation.

Принадлежит: DIC Corp

An object to be achieved by the present invention is to provide a resin composition for forming a receiving layer, the resin composition being capable of forming, among receiving layers that can carry a fluid such as an ink, a receiving layer having excellent, adhesion to various types of supports and capable of forming a receiving layer which has excellent printing properties without causing bleeding of a fluid such as an ink. The present invention relates to a resin composition for forming a receiving layer, the resin composition containing a urethane resin (A), a vinyl polymer (B), and an aqueous medium (C), in which the urethane resin (A) has an alicyclic structure in an amount of 2,000 to 5,500 mmol/kg relative to the total amount of the urethane resin (A), and a hydrophilic group.

Принадлежит:

The invention makes it possible to use a coating liquid of a fine cellulose fiber (a natural material) and to form a coated layer which can be used as a various-functions layer such as a gas barrier layer and water vapor barrier layer etc. by achieving good adhesiveness and coatability of the coating liquid, and as a result, provides a laminated material in which temporal degradation of a substrate and the fine cellulose fiber layer is prevented. The laminated body includes a substrate, an anchor layer arranged on a surface the substrate, and a fine cellulose fiber layer containing a fine cellulose fiber having a carboxy group, wherein the anchor layer contains at least one resin having a carboxy group, sulfonate group, amino group or hydroxyl group. 1. A laminated body comprising:a substrate;an anchor layer on a surface of said substrate; anda fine cellulose fiber layer on said anchor layer, said fine cellulose fiber layer containing a fine cellulose fiber having carboxy groups, whereinsaid anchor layer contains a resin having at least one functional group selected from the group consisting of carboxy group, sulfonate group, amino group and hydroxyl group.2. The laminated body according to claim 1 , wherein said fine cellulose fiber is oxidized cellulose in which said carboxy groups are introduced by an oxidation reaction and a content of said carboxy groups in said fine cellulose fiber is in the range of 0.1-5.5 mmol/g.3. The laminated body according to claim 2 , wherein said fine cellulose fiber has a number average fiber diameter in the range of 0.001-0.200 μm.4. The laminated body according to claim 3 , wherein said carboxy groups in said fine cellulose fiber form ammonium salts or amine salts.5. The laminated body according to claim 3 , wherein said resin contained in said anchor layer is a polyester resin claim 3 , a polyamide resin claim 3 , a polyurethane resin claim 3 , a polyacrylic acid resin claim 3 , a polyolefin resin or a copolymer of any combination ...
