AI Technical Summary
Existing police interception equipment cannot effectively solve the problem of people inside vehicles being able to see police officers, while police officers cannot see the situation inside the vehicle, leaving law enforcement officers in an unknown threat and the risk of handling the situation has not been reduced.
An automotive anti-visual-impedance spray was prepared using acrylate copolymers and modified carbon black powder. Through chemical bonding and molecular-level intercalation, a dense visual-impedance film layer was formed, blocking the view of occupants inside the vehicle.
It can quickly form a visual barrier, reduce the ability of people inside the vehicle to observe the outside world, improve law enforcement safety, reduce casualties and traffic losses, is easy to clean and restore to its original state, is flexible in use, and reduces law enforcement costs.
