Core–Shell Quantum Dot-Embedded Polymers for Antistatic Applications
ACS Applied Nano Materials, 2023 Electrical charges develop on the surfaces of two insulator materials when they are in contact and separated. The retention of charges on insulator polymers causes material losses and hazards in industries using these polymers. Here, we show that a set of core-shell quantum dots embedded into a common polymer can destabilize the charges on the polymer.
