Preparation of composite/nanomaterials - Ultrasonic spraying

Since the beginning of the 21st century, with the continuous development and innovation of nanotechnology, nanomaterials have demonstrated enormous application potential in multiple fields. Nanomaterials can be used to manufacture drugs, improving bioavailability, reducing drug dosage, and enhancing efficacy; they can also be used in cancer treatment and cell imaging. Furthermore, nanomaterials can be used to manufacture high-efficiency, low-cost solar cells, photosynthetic walls, and energy-saving building materials. They can also be used to manufacture small, high-performance materials, such as superstrong and superhydrophobic materials. Nanomaterials can also be used to manufacture microelectronic components, such as nanowires and nanotubes. In short, nanomaterials have broad application prospects and are expected to be applied to even more fields in the future, exhibiting even more outstanding performance.

Applications of TiO₂ Composite Materials

● New Energy: Used as a photoanode in dye-sensitized solar cells to improve photoelectric conversion efficiency; used as a negative electrode material or separator coating in lithium batteries to improve battery capacity and cycle stability.

● Environmental Protection and Photocatalysis: Can degrade organic pollutants, sterilize and disinfect; used in wastewater treatment, air purification, and self-cleaning coatings.

● Coatings and Pigments: The primary application area. Rutile is used in exterior wall coatings, automotive paints, and other applicaions requiring high weather resistance; anatase is used in interior wall coatings, improving coating whiteness, hiding power, and weather resistance.

When preparing titanium dioxide (TiO₂) coatings using Shanghai Yangmi's ultrasonic spraying technology, the substrate adaptability is extremely strong, covering rigid substrates, flexible substrates, porous substrates, and micro-nano-scale precision substrates. Compared with traditional spraying methods (air spraying, high-pressure spraying), sol-gel impregnation, spin coating, etc., ultrasonic spraying technology has core advantages in TiO₂ coating preparation, such as uniform film formation, uniform particle size distribution, and high raw material utilization. It is especially suitable for the precision preparation requirements of functional TiO₂ coatings (photocatalysis, photoelectric, UV protection, self-cleaning).

Core Advantages

1. High coating uniformity and precise, controllable film thickness: Film thickness can be precisely adjusted from the nanometer (tens of nm) to the micrometer (tens of μm) level through ultrasonic spraying parameters and precursor concentration, suitable for applications with stringent thickness requirements such as photovoltaic photoanodes and sensor sensitive films.

2. Extremely high raw material utilization, reducing production costs: High raw material utilization significantly reduces raw material costs for large-scale production.

3. Non-destructive spraying, suitable for flexible/precision substrates: Shanghai Yangmi's ultrasonic spraying flexible roll-to-roll equipment enables continuous production of TiO₂ coatings.

4. Strong coating adhesion and excellent weather resistance: Ultrasonic atomization deposits uniformly onto the substrate surface at low speed, ensuring sufficient contact between the precursor and the substrate surface. After online drying, the TiO₂ coating forms a physical adsorption + chemical bond with the substrate, resulting in adhesion far superior to coatings produced by traditional spraying.
