Bespoke Specialty Dispersions from Avantama
Avantama is a leading manufacturer of tailor-made specialty dispersions for cutting-edge printed electronics. We offer advanced nanoparticle solutions for organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and quantum dot technologies at commercial-scale production quality with excellent levels of reproducibility. This supports both research and development into novel device architectures and method development for cost-effective and efficient product manufacturing.
This blog post will explore our unique service in greater detail, with an emphasis on tailor-making specialty dispersions.
Nanoparticles for Specialty Dispersions
Nanoparticle engineering is at the heart of our technology and our expertise. We have prepared over 10,000 distinct nanoparticle compositions for specialty dispersions, including multi- or single element oxides and metal salts. These can be augmented through optional doping to alter the photonic or electronic capacities of the material. Doped and untreated nanoparticles can be fine-tuned to display narrow particle size distributions across a range of 10 – 100 nanometers (nm).
Unique nanoparticle compositions can be produced in batches on the multi-ton scale with outstanding degrees of yield reproducibility.
Solvents for Specialty Dispersions
Bespoke nanoparticles are dispersed in a liquid solvent for distinct deposition requirements or to stabilize the dispersant particles. Specialty dispersions are subject to robust assessments throughout product development, enabling tight control of the hydrodynamic geometries of dispersed nanoparticles to ensure the highest-quality relationship between a nanoparticle’s chemical composition and size, and its solvent media. Typical solvents include water, acetone, ethanol, and monomers.
Solid nanoparticles can also be used in solvent-free printing. We supply specialty dispersions suitable for all major printing methodologies, including dip coating, inkjet printing, screen printing, slot-dye coating, and spin coating.
The Applications of Specialty Dispersions
Specialty dispersions are engineered to exhibit distinct optical and electronic properties for thin films products. They can be used to design and manufacture charge selective layers for semiconductor structures.
These highly commercial sectors require reproducible materials for batch manufacturing of high-value products. Avantama is prepared to synthesize specialty dispersions for customer-specific requirements and optimize the development process to reduce ongoing costs and improve client ROIs.
Custom Specialty Dispersions with Avantama
Our R&D team can develop nanoparticles of novel compositions and expertly asses their hydrodynamic and chemical properties to pair the material with suitable solvent media. This process is designed to deliver reproducible specialty dispersions with ideal properties for your existing printing techniques and application.
