Titanium Dioxide Nanoparticles (PVP Modified)

Product Overview
Titanium dioxide nanoparticles (PVP modified) are surface-modified with Polyvinylpyrrolidone (PVP) to enhance their dispersion in water. The rutile-type titanium dioxide possesses excellent optical, chemical, and photocatalytic properties, making it widely used in air purification, sunscreen, plastics, and rubber materials. Surface modification with PVP improves the stability and dispersion of titanium dioxide, further expanding its range of applications.

Key Features

• Optical Properties:Exhibits excellent refractive index and high optical activity, strongly absorbing and scattering ultraviolet light while allowing visible light to pass through.
• Chemical Stability:Offers outstanding chemical and thermal stability, resisting reactions with other substances.
• Photocatalytic Properties:Capable of catalyzing various chemical reactions under light exposure, such as decomposing organic compounds and killing bacteria.
• Self-Cleaning Ability:Exhibits superhydrophilicity, breaking down organic contaminants on surfaces under visible light exposure to maintain clean surfaces.
• Water Dispersion:PVP modification enhances the dispersion of titanium dioxide in water, facilitating easier application in aqueous systems.

Applications

• Photocatalysts and Air Purification Products:Utilizes its photocatalytic properties to decompose harmful gases and inorganic compounds in the air, effectively purifying the environment.
• Sunscreen Cosmetics:Strongly absorbs and scatters ultraviolet rays, widely used in sunscreen products to provide superior UV protection.
• Plastics, Rubber, and Functional Fibers:Incorporated into plastics, rubber, and functional fibers to enhance aging resistance, mechanical strength, and weather resistance.
• Other Applications:Can be used in coatings, inks, ceramics, and more to improve product performance and quality.
