Protective film structure with additional special functional surface

The utility model discloses a protective film structure with an additional special functional surface. From bottom to top, the device sequentially comprises a shell, wherein the first bonding layer isarranged on the lowermost layer, the structural strength layer is arranged on the middle layer, and the second bonding layer is arranged on the uppermost layer. The first bonding layer is used for fixing the protective film on the surface of a pasted object; the structural strength layer is used for guaranteeing that the protective film has certain mechanical strength, and small particles of large-specific-surface-area substances with special auxiliaries are attached to the upper surface of the second bonding layer and evenly cover the surface of the second bonding layer. According to the utility model, small particles with large specific surface areas are used as carriers; according to the utility model, the special auxiliary agent is adsorbed on the micro-particles of the substance withlarge specific surface ar
