Surface modifiers for nanoparticles
At Croda we offer a range of customisable surface modifiers to allow for self-dispersibility and improved functionality of a variety of nanoparticles used in applications including quantum dots, nanosilver inks, and colloidal nanosilica. Unique combinations of anchoring groups and stabilizing tails are offered and possible for tailored development.
Our customisable surface modifiers permanently bind to the surface of nanoparticles and improve their dispersibility and stability.
Solution to enhance advanced particle technologies
Enabling quantum dot display technologies
As consumers demand increased vibrance in their viewing experience, display technology manufacturers must continue to innovate to provide sharper and clearer images to their screens. Improved resolution is no longer enough to satisfy consumers, so quantum dots provide an alternative route to improved perception.
Quantum dots are inorganic semiconductor nanocrystals, stabilised by organic ligands, that give off bright colours with a light or electrical stimulus. Therefore, quantum dots enable brighter colours to bring the viewing experience to life.
Our ligands for quantum dot shells are of high purity and designed to bring beneficial properties including enhanced brightness. Innovative manufacturing processeses minimize impurities for optimal colour
Croda’s ligands in quantum dot shells also assist in:
- Control of the building of the quantum dot particle during synthesis
- Particle size stability
- Surface passivation (removing defects on the quantum dot surface, allowing it to emit colour)
