Conductive V2C MXene and paralelectric SrTiO3 containing polymer composites with high dielectric constant

A multifunctional flexible sensor based on PI-MXene/SrTiO3 hybrid aerogel for tactile perception

“…Moreover, the best approach to assemble flexible sensors via thermoelectric materials is to design flexible sensors as porous aerogels with an appropriate thickness for realizing the rapid formation of temperature gradients 30 ; this technique can improve the response time and accuracy of devices. However, nanocomposite aerogels derived from two inorganic materials, MXene and SrTiO 3 often exhibit relatively low mechanical strength, as previously reported, 31 which can be enhanced by increasing the number of crosslinking points between the internal lamellar nanosheets of aerogels. However, polyimide (PI) is a high temperature-resistant binder that can effectively cause inorganic lamellas to mutually connect with each other by chemical bond crosslinking, 32 , 33 , 34 and this process is expected to lead to the preparation of a high-strength sensitive aerogel.…”

Achieving remarkable energy storage enhancement in polymer dielectrics via constructing an ultrathin Coulomb blockade layer of gold nanoparticles

“…7(b). [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] This clearly shows that the highest discharge energy density occurs in the low gold content composite films. In our work, the P(VDF-HFP) film with 0.0064 vol% gold nanoparticles exhibits a discharge energy density of 13.02 J cm À3 owing to the synergetic enhancement of dielectric permittivity and breakdown strength, which is higher than those of films with high filling fraction fillers.…”

Quantum Mechanical Study of the Dielectric Response of V2C-ZnO/PPy Ternary Nanocomposite for Energy Storage Application

“…In this study, we used first-principles calculations to investigate the dielectric response of PPy/V 2 C Mxene-ZnO. For our calculations, we used the density functional theory (DFT) method, which is a widely used and well-established first-principles calculation method [40][41][42][43][44][45][46][47][48]. DFT is based on the idea that through the self-consistent solution of the Kohn-Sham equations, the total energy of a system may be represented as a function of the electron density.…”
