Referat pt. "Modeling, Analysis and Sensor Development with MXenes and MXene Nanocomposites" wygłosi dr Shreyas Srivatsa (ACMiN AGH).

Streszczenie:

Two-dimensional (2D) nanomaterials called MXenes (surface terminated Titanium Carbide, Ti3C2Tx; Tx: -F, -OH, -O), discovered in 2011 [1], have a unique combination of properties of conductivity, hydrophilic behavior, film-forming ability, elasticity etc. These properties help in the fabrication of pure MXene films and MXene nanocomposites [2], [3] which can have multifunctional sensing behavior. MXenes are also being used around the world in applications of battery technology, supercapacitors, energy harvesters, wireless communication, etc. The use of polymer as a matrix with MXene fillers helps in controlling the electro-mechanical properties of the nanocomposites. Modeling the MXene structures from the nanoscale to the macroscale is necessary for predicting the physical properties of the pure MXene films and MXene nanocomposites as well as studying the physical behavior across the scales. Analytical and numerical models are being developed and analyzed for the MXene films to estimate electro-mechanical properties. Experimental investigations on the MXenes films for their use in sensors are also being done. The present talk will focus on modeling and analysis of MXene structures and their application in sensor development. MXene based strain sensors, acoustic emission sensors, impact sensors, pressure sensors, etc. being developed for Structural Health Monitoring (SHM) of engineering structures will be discussed.
