AI Technical Summary
Existing medical electret patches have poor charge storage stability, and highly conductive fillers are prone to charge loss. Furthermore, traditional molding processes cannot simultaneously ensure the microstructure and skin adhesion, affecting the effective transmission of electrostatic fields.
Aryl functionalized graphene is combined with a polar polymer matrix to construct multi-level deep energy traps through π-π conjugated structures and strong electron-withdrawing groups. Charge trapping agents and piezoelectric agents are introduced as synergistic agents. Combined with ultrasonic dispersion, fused deposition modeling 3D printing and corona charging processes, the graphene is ensured to be dispersed at the nanoscale and ordered, thus constructing a stable charge storage structure.
It significantly improves charge storage stability and skin adhesion, ensuring that the electrostatic field acts precisely and continuously on specific acupoints, improving sleep quality and relieving insomnia symptoms, without the risk of drug dependence or skin irritation.
