摘要： Polymeric micro?bers, particularly the ?uorinated copolymers’ ?bers, are promising functional materials for photoelectric devices, sensing, and energy storage due to their various surface characteristics. However, to obtain the high ?uorine content copolymer-based ?bers with considerable uniformity is likely to be especially challenging, which seriously debilitates their applications in sensor devices. Herein, for the ?rst time, we presented a high ?uorine content platinum porphyrin-grafted poly(isobutyl methacrylate-co-dodeca?uoroheptyl methacrylate) copolymers (PtTFPP-p(IBM-co-DFHMA)) micro?brous thin-?lms used as optical oxygen sensors. The porous thin-?lm frameworks were formed of uniform micro?bers, which a?orded an exceptional improvement in sensitivity and exhibited 584% higher sensitivity than the solid sensing ?lm owing to the large speci?c surface area, porous structures and oxygen di?usion enhancement by ?uorine elements. Additionally, the remarkable emission intensity-changing characteristic of the micro?ber sensing ?lm under various air pressures facilitates convenient visualization of pressure distributions on ?lm surface. The characteristics are particularly important for the computational ?uid dynamics simulations in various sensing ?elds such as unsteady ?ow visualization and unsteady pressure measurements, etc. Owing to its attractive advantages and versatile performance, ?uorine-containing copolymers ?bers are expected to provide a new strategy for the rational design of high performance gas sensor devices.
