Oligoaniline-assisted self-assembly of polyaniline crystals

Abstract

The presence of a small amount of oligomer can induce ordering and crystallization of the parent conducting polymer, resulting in highly conductive, compositionally homogeneous crystals with defined molecular weights.

VIS-IR electrochromic device with electromagnetic wave absorption function based on a Fe3O4@PANI composite material

“…Polyaniline (PANI), as a multifunctional material, can be used not only as an electrochromic material, but also as an electric loss type electromagnetic wave absorbing material with potential application value. [15][16][17][18][19] However, pure PANI lacks magnetism, has poor impedance matching and single loss mechanism as an electromagnetic wave absorbing material, resulting in a narrow absorption bandwidth. [20][21][22][23][24] Therefore, compositing electric loss type PANI with magnetic loss type electromagnetic wave absorbing materials is an effective way to obtain electromagnetic wave absorbing materials with good impedance matching.…”
