Interfacial Interactions and Interfacial Polarization in Polyazomethine/MWCNTs Nanocomposites
Composites Science and Technology, 2020Abstract We prepared the polyazomethine/MWCNTs nanocomposites varying in the nanofiller loading (from 0 to 1.5 wt%). Taking into account an upshift of the characteristic D and G bands of MWCNTs in the Raman spectrum of the nanocomposite, we confirmed the interfacial interactions between MWCNTs and polymer chains.

Insight Into Interfacial Polarization for Enhancing Piezoelectricity in Ferroelectric Nanocomposites
Small, 2023Abstract The interfacial effect is widely used to optimize the properties of ferroelectric nanocomposites, however, there is still a lack of direct evidence to understand its underlying mechanisms limited by the nano size and complex structures.

Cumulative polarization in conductive interfacial ferroelectrics
Nature, 2022Ferroelectricity in atomically thin bilayer structures has been recently predicted1 and measured2-4 in two-dimensional materials with hexagonal non-centrosymmetric unit-cells. The crystal symmetry translates lateral shifts between parallel two-dimensional layers to sign changes in their out-of-plane electric polarization, a mechanism termed 'slide ...

Modulation of Organic Interfacial Spin Polarization by Interfacial Angle
Chemical Physics Letters, 2017Abstract Based on ab initio theory, we theoretically investigated the interfacial spin polarization by adsorbing a benzene-dithiolate molecule onto a nickel surface with different interfacial angles. A variable magnitude and even an inversion of the interfacial spin polarization are observed with the increase of the interfacial angle.

ACS Applied Materials & Interfaces, 2021
Molecule-based ferroelectrics has attracted much attention because of its advantages, such as flexibility, light weight, and low environmental load. In the present work, we examined an organic metal|insulator|semiconductor|insulator|metal (MISIM) device structure to stabilize the interfacial polarization in the S layer and to induce polarization ...
