Self-cleaning coatings

Номер: US20120010314A1

Автор: Kevin D. Burgess, Paul A. Charpentier

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.

A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.

A process for treatment of nanoparticles of mineral filler for obtaining 5 processed nanoparticles for use in polymerization in the presence of nanopartciles which includes the steps of (a) drying a mineral filler with an inert gas for remove catalyst poisons; (b) mixing the mineral filler dried obtained in step (a) with a swelling agent in a liquid state or near a critical state or in the supercritical state; (c) subjecting the swelling agent of the 10 mixture obtained in step (b) to an endoenthalpic or isoentalphic phase change by altering the conditions of the temperature and/or pressure; (d) subjecting the nanoparticles of the mixture obtained in step (c) to contact of scavenging agent to react with catalyst poisons; then the mixture obtained in step (d) can be dried in a step (e) with an inert gas to remove sub-products 15 from scavenging agent and catalyst poisons to obtain the treated nanoparticles. 1. A process for treatment of nanoparticles of a mineral filler , which comprises the steps of:a. Drying a mineral filler with an inert gas;b. Mixing the dried mineral filler obtained in step (a) with a swelling agent in a liquid state, or near a critical state or in a supercritical state;c. Subjecting the swelling agent of the mixture obtained in step (b) to an endoenthalpic or isoenthalpic phase change, by altering the conditions of temperature and/or pressure; andd. Subjecting the mixture obtained in step (c) to contact with a scavenging agent.2. The process as claimed in claim wherein step (a) occurs in a temperature range of 20 to 160° C. , preferably between 100 and 120° C. , at a pressure range of from 0 to 16.000 mmHga , preferably between 0 and 740 mmHga , for a period of time varying between 2 and 24 hours , preferably from 4 to 8 hours3. The process as claimed in claim wherein step (a) occurs using a dynamic drying system selected from the group consisting of a fluidized bed dryer , a rotary dryer and a rolling bed dryer.4. The process as claimed in ...
