The invention belongs to the field of water-based
polymer functional materials, and particularly relates to a water-soluble
polyaniline composite liquid, a core layer atomized spray liquid, artificial bionic
skin and a preparation method. The
polyaniline composite liquid is synthesized in a
polymer acid
doping mode, serves as a network path to transmit core layer
dielectric signals, and endows a
skin layer with a piezoelectric sensing effect. The artificial bionic
skin is prepared from core layer atomized spray liquid and shell layer atomized spray liquid prepared from
alcohol-soluble cationic fluorinated
polyurethane through a core-shell electrostatic atomization technology, and the artificial bionic skin has the advantages of air permeability,
moisture permeability, hydrophobicity, oleophobicity,
antibiosis, high strength, high flexibility,
high conductivity and
low resistance. A three-dimensional object can be sprayed at any angle through the electrostatic atomization technology, and the
coating of a three-dimensional mechanical structure and joints of a
robot is realized. The artificial bionic skin can be applied to medical
wound skin repair, meanwhile, the core layer can be directly sprayed on the heart or
wrist part of a
human body due to the excellent
conductivity, and possibility is provided for
electric signal transmission of the
robot skin in the later period or human
heartbeat monitoring applied to the medical field.
