Mechanism: The coating contains hydrophilic (water-attracting) groups (e.g., hydroxyl or carboxyl groups) that spread condensed water into a thin, transparent film instead of droplets.
Durability: Often achieved via permanent treatments like chemical grafting or co-extrusion during manufacturing.
Mechanism: Superhydrophobic surfaces (e.g., lotus-leaf-inspired textures) cause water droplets to bead up and roll off. However, this is less common for anti-fog PC, as hydrophilic coatings are more effective for transparency.

Conductive Additives: Embedded materials (e.g., carbon) create a conductive network within the PC matrix.
Surface Chemistry: Some versions use permanent anti-static agents that migrate to the surface, attracting moisture from the air. This thin layer of moisture allows charges to bleed off slowly and safely.
Result: Static charges don't accumulate; they flow across the surface and safely dissipate to ground (often via contact with grounded surfaces or operators).
