Material composition:The material of the thin film panel is the key factor determining the rate of electrostatic dissipation.If it is a conductive thin film panel,such as a panel containing conductive fillers such as carbon nanotubes and metal fibers,the static dissipation rate is relatively fast.These conductive fillers form conductive pathways within the material,allowing electrostatic charges to quickly conduct along the pathways.Taking the thin film panel with added carbon nanotubes as an example,static electricity can dissipate most of it within a few seconds to a dozen seconds.Because carbon nanotubes have excellent electrical properties and can provide conductive channels.
Humidity environment:Environmental humidity also has a significant impact on the static dissipation rate of thin film panels.In high humidity environments,the surface of thin film panels will adsorb a thin layer of water molecules.These water molecules can act as conductors,making static electricity easier to dissipate.Usually,when the environmental humidity reaches 60%-70%,the static dissipation rate on the thin film panel will be much faster than in low humidity environments(such as 20%-30%).This is because water molecules can form an electrolyte layer on the surface of the thin film panel,which facilitates the transfer of charges.
The surface area and shape of thin film panels:A larger surface area and complex shape are beneficial for the dissipation of static electricity.Because a larger surface area means more space to disperse electrostatic charges,complex shapes can increase the conduction paths of charges on the surface.For example,a thin film panel with many folds or protrusions can quickly conduct and dissipate electrostatic charges along these irregular shapes.In contrast,a flat and smaller thin film panel may have a slower rate of electrostatic dissipation.
Comparison of static dissipation rates of different types of thin film panels
Insulated thin film panel:This type of panel has a slow rate of static electricity dissipation,which may take several hours or even days to naturally dissipate static electricity.Because their materials themselves do not have conductivity,it is difficult for electrostatic charges to move inside or on the surface of the material.For example,ordinary polyethylene terephthalate(PET)insulation film panels accumulate static electricity on the panel after it is generated,which can only be gradually dissipated through very slow air ionization or accidental factors such as contact friction with other objects.
Anti static film panel:The static dissipation speed of anti-static film panel is moderate,and it can generally dissipate static electricity within a few minutes to several tens of minutes.They achieve electrostatic protection by adding anti-static agents to the material.Antistatic agents can absorb moisture from the air and form a conductive layer on the surface of the panel,allowing for faster transfer and dissipation of electrostatic charges.
