Description

Polyether sulfone material, low-defect-sensitivity polyether sulfone capacitance film and preparation method
Technical Field
The application relates to the field of high polymer capacitance films, in particular to a polyether sulfone material, a low defect sensitivity polyether sulfone capacitance film and a preparation method thereof.
Background
The capacitor is widely applied to modern electronic and electric equipment such as pulse power equipment, a mobile power supply system, a hybrid electric vehicle and the like as a high-power energy storage device. In order to achieve miniaturization and weight reduction of power electronics systems, there is a need to find polymer dielectric films with high energy storage densities and high operating temperatures. The maximum operating temperature of a polymeric material is limited by its thermal stability, such as glass transition temperature, for example, a conventional biaxially oriented polypropylene (BOPP) film, which has a service temperature below 100 ℃ and limits its range of applications. Polyether sulfone (PES) is a high-temperature-resistant special engineering plastic, and has the advantages of high glass transition temperature (215 ℃), good thermal stability, thermoplasticity, solubility, excellent processability and high working temperature.
However, the inventors found in the study that the poly-sealed capacitor film has defect sensitivity: the polymer film is coated with aluminum or zinc metal on the surface before being formed into a capacitor. In order to maintain uniformity of thickness of the vapor deposited metal layer, it is required that the conveying speed of the polymer film is uniform, and the polymer film is wound around a steel roller, and a stable conveying force is provided by the steel roller. To avoid wrinkling of the film during transport, the steel rolls exert tension on the polymer film, which is in a taut state on the steel rolls. When gel points or physical defect points (phi is less than or equal to 1 mu m) exist on the polyethersulfone film, stress concentration is easy to occur at the defect, the polyethersulfone film is easy to be broken under the condition of tightening, the whole vacuum evaporation process is greatly influenced, the material waste is serious, and the popularization of the polyethersulfone capacitor film is hindered.
In addition, the energy storage capacity of the pure polyethersulfone is obviously reduced along with the increase of the working temperature, particularly, the low energy storage density level at the high temperature of 150 ℃ also influences the application of the capacitor at the high temperature, so that the technical problem to be solved is how to maintain the certain energy storage density of the polyethersulfone at the high working temperature.
Disclosure of Invention
In order to reduce the defect sensitivity of the polyethersulfone capacitor film, the application aims to provide a polyethersulfone material, and a polyethersulfone film using the polyethersulfone material has higher tearing strength, reduces the defect sensitivity and is more suitable to be used as the capacitor film.
The application provides the following technical scheme:
the polyethersulfone material comprises the following components in percentage by mass:
65 to 95 percent of polyether sulfone, 2 to 30 percent of polycarbonate-siloxane copolymer and 0.2 to 3 percent of chain extender.
The inventors have found in the study that increasing the tear strength of polyethersulfone films helps to reduce defect sensitivity. However, the conventional toughening agent cannot meet the requirements for preparing the polyethersulfone capacitance film because of the glass transition temperature (T) g ) Extremely low (< -20 ℃) these thermoplastic elastomers can greatly reduce the high temperature resistance of polyethersulfones, affecting the high operating temperature properties of polyethersulfones, while Polycarbonates (PC) and the like are similar to the mechanical properties of polyethersulfones, and cannot improve the defect sensitivity of polyethersulfones. The application compounds the polycarbonate-siloxane copolymer with the polyether sulfone base material, the polycarbonate-siloxane copolymer is a copolymer of bisphenol A type carbonate structural unit and siloxane structural unit, and the heat-resistant temperature is not lower than 120 ℃. When the polyethersulfone materials are melt blended, interfacial gaps are eliminated by the polyethersulfone and polycarbonate-siloxane copolymer under the action of a chain extender, the compatibility of two phases is improved, meanwhile, the viscosity of the polycarbonate-siloxane copolymer is increased, the phenomenon of melt phase separation caused by overlarge viscosity difference of the two phases is prevented, the high temperature resistance of a polyethersulfone main body is maintained, meanwhile, the elasticity and strain resistance of the polyethersulfone film are improved, the tearing strength is improved, and the improvement of the tearing strength is helpful for weakening the defect sensitivity of the polyethersulfone film. Meanwhile, on the basis that the higher dielectric constant and the relatively lower dielectric loss of the polyethersulfone endow the capacitor film with higher energy storage density, the dielectric property and the high-temperature electric field breakdown resistance strength of the polyethersulfone are further improved, and the relatively lower dielectric loss is kept, so that the polyethersulfoneThe film can store charges at a higher temperature, so that the high-temperature energy storage density of the polyethersulfone is improved, and the energy storage density of the polyethersulfone material at a high temperature such as 150 ℃ is equivalent to that of a pure polyethersulfone capacitor film at normal temperature.

The properties of the capacitance films prepared in the above examples and comparative examples are shown in table 1 below.
Table 1 test results
As shown in examples 1 to 4, the addition of the polycarbonate-siloxane copolymer to the polyethersulfone increases the tearing strength of the polyethersulfone, thereby improving the tearing resistance of the polyethersulfone against physical defects, further improving the dielectric constant of the polyethersulfone and the electric breakdown field strength at high temperature, maintaining relatively low dielectric loss (the dielectric loss is increased but not protruded), providing the modified polyethersulfone capacitor film with stronger charge storage capacity at high temperature, improving the high temperature storage density, and the storage density of the polyethersulfone capacitor film at 150 ℃ is equivalent to the storage density of the pure polyethersulfone capacitor film at normal temperature. And when 83% -95% of polyethersulfone, 4% -15% of polycarbonate-siloxane copolymer and 0.3% -1.8% of chain extender are used, the balance result of better tensile strength and tearing strength can be obtained. However, when the chain extender is omitted from the use of comparative example 2, the polycarbonate-siloxane copolymer cannot withstand thermal processing at 300 ℃ or higher, and is extremely liable to cause breakage of the molecular chains of the polycarbonate-siloxane copolymer, and thus the tensile strength and tear strength of comparative example 2 are lower than those of example 2, or when the amount of the polycarbonate-siloxane copolymer is increased beyond the scope of the present application as shown in comparative example 3, since polyethersulfone and polycarbonate-siloxane copolymer are not completely compatible polymers, interfacial voids exist, and the higher the polycarbonate-siloxane copolymer content, the more the interfacial voids, the chain extender is insufficient to fill all the interfacial voids, severely affecting the breakdown field strength of the blend. Although the increase in the content of the polycarbonate-siloxane copolymer increases the contribution of the tear strength of the polycarbonate-siloxane copolymer itself, resulting in an increase in the tear strength, the energy storage capacity is severely reduced.
