摘要: Abstract Electrospinning was employed to obtain uniformly distributed Cadmium Selenide (CdSe)/Zinc Sulfide (ZnS) core shell quantum dot (QD) encapsulated nanofibers in polymeric mixture of 4:1 ratio polystyrene (PS) and polystyrene-co-maleic anhydride (PSMA). Fluorescence scanning electron microscopy (SEM) measurements were used evaluate the uniform size distribution uniformity PS–PSMA with high aspect ratios. The introduction QDs only into induced electrical conductivity. They also showed a two three fold increase conductivity presence volatile organic compounds. obtained quantum-dot (Qd-NFs) 600–650 nm thick, photostable for more than six months, applicable conductance or gas-based sensing applications.
