Conductive quantum dot-encapsulated electrospun nanofibers from polystyrene and polystyrene-co-maleic anhydride copolymer blend as gas sensors |
| 초록 |
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 of polystyrene (PS) and polystyrene-co-maleic anhydride (PSMA). Fluorescence and scanning electron microscopy (SEM) measurements were used to evaluate the uniform size distribution and uniformity of PSPSMA nanofibers with high aspect ratios. The introduction of QDs only into the PSPSMA nanofibers induced electrical conductivity. They also showed a two to three fold increase in electrical conductivity in the presence of volatile organic compounds. The obtained quantum-dot nanofibers (Qd-NFs) were 600650 nm thick, photostable for more than six months, and applicable for electrical conductance or gas-based sensing applications. |
