Abstract: A mesh type atomizer according to an embodiment includes a porous thin film having a multi-hole structure, a metal layer covering a remaining area except a nozzle area in which droplets are sprayed through the holes on a surface of the porous thin film, and an ultrasonic transducer to output ultrasonic waves to vibrate the porous thin film. According to an embodiment, it is possible to atomize a liquid into nanometer-level fine particles using the porous thin film including nanometer sized holes. It is possible to precisely adjust the sprayed droplet size by setting the shape, size and cycle of the nozzle in the manufacturing process, and it is possible to selectively increase the strength of the mesh by growing the metal material in the hole of the porous thin film through electroplating.

Abstract: The disclosure relates to a MXene-polymer composite comprising MXene and a UV curable polymer, and a sensor comprising the same. Particularly, the MXene-polymer composite according to the disclosure polymerizes the MXene with the UV-curable polymer to stably disperse the MXene in a porous hydrogel matrix, thereby exhibiting a larger surface area and enabling local patterning, and when the MXene-polymer composite is applied as a sensor, excellent electrochemical sensitivity and gas reactivity can be obtained.
