Ionic Crystal Structures

Ionic Crystal Structures

Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Hybridization of Atomic Orbitals I

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Background:

Hexagonal boron nitride (hBN) offers excellent stability and robustness, making it suitable for ionogel matrices.
Existing hBN ionogels are limited to macroscopic applications, lacking compatibility with high-resolution printing.
Development of printable ionogel inks is crucial for advanced electronic applications.

Purpose of the Study:

To develop aerosol jet-printable ionogel inks using exfoliated hBN nanoplatelets.
To characterize the properties of the printed hBN ionogels.
To demonstrate the application of these ionogels in printed flexible electronics.

Main Methods:

Liquid-phase exfoliation of bulk hBN powders to produce hBN nanoplatelets.
Formulation of printable inks by combining hBN nanoplatelets, ionic liquid, and ethyl lactate.
Aerosol jet printing for fabricating ionogel patterns with controlled thickness and resolution.

Main Results:

Successfully formulated and printed hBN ionogel inks using aerosol jet printing.
Achieved high room-temperature ionic conductivity (>3 mS cm⁻¹) and storage modulus (>1 MPa) in printed hBN ionogels.
Demonstrated fully-printed thin-film transistors on polyimide films with operating voltages below 1 V.

Conclusions:

Aerosol jet-printable hBN ionogel inks were successfully developed.
The printed hBN ionogels exhibit excellent ionic conductivity and mechanical properties.
These findings confirm the potential of hBN ionogels for fabricating high-performance printed and flexible electronics.
