In the field of electronic display and optical materials, PC (polycarbonate) optical film is widely favored for its excellent light transmittance, heat resistance and impact resistance. Especially in terms of electromagnetic wave shielding and antistatic performance, the thickness of PC optical film has become one of the key factors affecting its performance.In terms of electromagnetic wave shielding ability, thicker PC optical film tends to show stronger shielding effect. This is because electromagnetic waves are reflected and absorbed at the interface when passing through the medium. As the film thickness increases, the path of electromagnetic waves propagating in the film increases, thereby increasing the chance of them being absorbed or reflected. Therefore, in occasions where high electromagnetic wave shielding effect is required, such as the housing of electronic equipment, display screen protection, etc., it is more appropriate to choose a thicker PC optical film.However, this does not mean that the thicker the film, the better. While pursuing the electromagnetic wave shielding effect, factors such as the light transmittance, weight and cost of the film need to be considered. If the film is too thick, it may cause a decrease in light transmittance, increase the weight and cost of the equipment, and may even affect the appearance and portability of the product.In terms of antistatic performance, the thickness of pc optical film also plays an important role. Static electricity refers to the phenomenon caused by the imbalance of charge distribution on the surface of an object, which may cause damage or interference to electronic equipment. Thicker pc optical film can better disperse and neutralize electrostatic charges due to its larger surface area and volume, thereby reducing the risk of electrostatic discharge.However, it is worth noting that the thickness of the film is not the only factor that determines the antistatic performance. The material, surface treatment and additives of the film will also have a significant impact on the antistatic performance. For example, the antistatic ability of pc optical film can be further improved by adding antistatic agents or surface modification.In summary, pc optical film of different thicknesses has significant differences in electromagnetic wave shielding and antistatic performance. In practical applications, it is necessary to select the appropriate film thickness according to specific needs and use environment. At the same time, it is also necessary to comprehensively consider the light transmittance, weight, cost and other related properties of the film to achieve the best comprehensive effect. With the continuous advancement of science and technology and the continuous expansion of applications, the performance and application areas of pc optical film will continue to be expanded and improved.
