摘要

以柠檬酸和尿素为碳源和氮源,采用微波辅助水热法制备了NGQDs。反应时间为4 min后,得到了均匀分布的球形NGQDs,并将其负载到PANI/PAN上,通过原位聚合和静电纺丝制备了NGQDs/PANI/PAN复合材料。对优化后的静电纺复合纤维进行了表征,并将其用于酒精蒸汽传感。

Electrospun NGQDs/PANI/PAN Composite Fibers for Room Temperature Alcohol Sensing
The synthesis of NGQDs was carried out via a microwave-assisted hydrothermal method where citric acid and urea were used as carbon and nitrogen sources, respectively. Uniformly distributed and spherical NGQDs were achieved after a 4 minutes reaction time and these dots were further loaded onto PANI/PAN to produce NGQDs/PANI/PAN composite via in-situ polymerization and electrospinning. Optimized electrospun composite fibers were characterized and later used for alcohol vapor sensing.
