Multifunctional nanofiber mat for high temperature flexible sensors based on electrospinning
JOURNAL OF ALLOYS AND COMPOUNDS(2023)
摘要
The application environment and scenarios of flexible sensors are limited by the low temperature tolerance of the flexible substrate and the lack of protection of the sensitive layer surface. A flexible alumina-silicon oxide composite nanofiber mat (Al2SiO5) with high-temperature resistance is obtained based on electrospinning technique. The maximum tensile strength of the nanofiber mat reach 3.09 MPa and the maximum withstanding temperature exceeds 973 ?through parameter optimization. The patterned functional thin films are successfully prepared on the flexible Al2SiO5 nanofiber mat by using magnetron sputtering technology, vacuum vapor deposition technology and ink jet printing technology and other coating processes. Meanwhile, the process characteristics of the nanofiber mat prepared by electrospinning technique are fully utilized to realize flexible packaging of the high-temperature flexible sensors. Multifunctional nanofiber mats prepared based on electrospinning have great prospects for future applications in the field of flexible sensors.
