  • Quantum dot-polymer nanocomposite sensor array for chemical vapor sensing
    Patent number: 9970939
    Abstract: A method of forming a quantum dot-polymer nanocomposite sensing film for chemical vapor sensing is achieved by first obtaining a mass of a type of polymer having a characteristic of expanding or contracting responsive to exposure to at least one of a group of chemical vapors and obtaining a quantum dot (QD) suspension which comprises CDs having a CdSe/ZnS core-shell ratio. The polymer and solvent are mixed, the QD suspension is dried, and the dried QDs are added to the polymer solution and mixed to form a precursor solution. At least a portion of the precursor solution is deposited and spread onto a substrate and then air-dried to form the quantum dot-polymer nanocomposite sensing film.
