Abstract: A composite phase change material, including 65 to 80 parts of a phase change material and 20 to 35 parts of a binder by weight. The binder includes an acrylate monomer having a molecular weight of 50 to 300, an acrylate polymer having a molecular weight of 500 to 2000, and an initiator. The initiator in the composite phase change material can generate free radicals under the condition of ultraviolet light irradiation to initiate polymerization reactions between components of the composite phase change material, so that the composite phase change material is cured, thereby greatly accelerating a cure speed of the composite phase change material.

Abstract: The present disclosure provides a 5G icon display control method, a terminal device, and a storage medium. The 5G icon display control method includes: determining a target 5G icon display condition based on target setting information; obtaining a network status parameter; and displaying a 5G icon, in response to the network status parameter meeting the target 5G icon display condition. The network status parameter includes at least one of a 5G network registration status, a E-UTRAN new radio dual connection status, an LTE network connection status, or a 5G/LTE dual connection network coverage status. When the target setting information is a network operator used by the terminal device, the terminal device may adopt different 5G icon display conditions according to different network operators.

Abstract: Disclosed is a self-temperature-limiting electric heating film and a preparation method therefor. The self-temperature-limiting electric heating film comprises a substrate, an electric heating layer arranged on the substrate, and two electrodes arranged on the electric heating layer. The electric heating layer comprises a heating block and a temperature-limiting block connected to the heating block. The temperature-limiting block comprises titanate and a substrate containing a first doping element, and the temperature-limiting block is used for limiting the temperature of the electric heating film. The first doping element is a rare earth element. The substance containing the first doping element is an elementary substance containing the first doping element or a compound containing the first doping element.

Abstract: An ink includes the following ingredients by weight: pigment: 5 to 10 wt %; dispersant: 1 to 5 wt %; photoinitiator: 5 to 8 wt %; monofunctional reactive monomer 10 to 15 wt %; multifunctional reactive monomer: 25 to 40 wt %; acrylic resin: 20 to 35 wt %; coupling agent: 2 to 5 wt %; defoamer: 0.1 to 1 wt %; and leveling agent: 0.1 to 1 wt %. The ink according to this application can concurrently meet various performance requirements such as deep curing, high adhesion, high resistance to abrasion and perspiration, and ease of correction.
