This invention discloses an antistatic protective film, its preparation method, and its applications, belonging to the field of protective films. The antistatic protective film, from bottom to top, comprises a release layer, an antistatic
voltage-sensitive
adhesive layer, a gradient
hybrid antistatic layer, and a substrate layer. The gradient
hybrid antistatic layer includes: 8-12 parts of a polyether ester
amide-modified
graphene hybrid antistatic agent, 60-70 parts of waterborne
polyurethane resin, 2-3 parts of a first crosslinking agent, 0.5-1 parts of a dispersant, and 15-20 parts of deionized water. This invention hybridizes polyether ester
amide with modified
graphene through covalent bonding, forming a dual-channel conductive mechanism of ions and electrons, resulting in stable antistatic performance without migration. The gradient hybrid antistatic layer and the antistatic
voltage-sensitive
adhesive layer contain the same hybrid
antistatic agent, forming a homologous interpenetrating network between the
layers, resulting in strong adhesion and no
delamination. The preparation method is simple, and the product can be applied to the protection of
flexible display devices and precision electronic components.
