Of these, alkamide is particularly preferred.
- the separator of the present invention is, for example, the above separator constituting member is processed into a short fiber having a fineness of 0.05 to 25 denier and a length of about 1 to 50 mm by a usual method, It is formed into a sheet by an appropriate paper machine, and the obtained sheet is rolled with a metal power render roll, for example, at a temperature of 100 to 400 ° C and a linear pressure of 50 to 400 kg Z It can be manufactured by hot-pressing in cm.
- the electric or electronic component using the separator of the present invention can be subjected to a heat treatment during its manufacturing process, for example, after being wound together with an electrode such as an aluminum foil having fine pores or activated carbon, and thereby, The residual moisture in the micropores can be removed.
- the heat treatment of the separator is carried out at a temperature of 200 ° C or more, for example, by heating the separator in an atmosphere where the ambient temperature is within the range of 300 ° C and 10 ° C for about 45 minutes. It can be performed by holding it.
- the surrounding atmosphere at this time is Separe It is preferable to use a gas atmosphere that does not cause a chemical reaction with the gas, for example, a nitrogen atmosphere, an argon atmosphere, or a vacuum.
- the separator was cut into a circle having a diameter of 2 Omm, sandwiched between two SUS electrodes, and calculated from the AC impedance at 6 OkHz. At this time, the measurement temperature was 25 ° C.
- a 1 M solution of lithium borofluoride in ethylene carbonate and propylene carbonate (11 weight ratio) was used as the electrolytic solution.
- a polymetaphenylene isophthalamide fiber was manufactured by a method using a wet precipitator composed of a combination of a stator and a rotor described in Japanese Patent Publication No. 52-151624. This was treated with a disintegrator and beater to adjust the weight average fiber length to 1.2 mm.
- the above separator was heat-treated at 300 ° C for 45 minutes in the air using a hot air dryer. At this time, in order to maintain the form, the separator was held in a vertical state by attaching a weight so that the tension per width was 0.5 gZmm.
- Table 1 shows the main characteristic values of the separator thus obtained.
- Table 2 shows the main characteristic values of the separator thus obtained.
- the electrical conductivity of the electrolyte was 4.6 (mS / cm).
- the separators of Examples 1 and 2 do not increase in internal resistance after heat treatment at 300 ° C for 45 minutes, and are considered to have sufficient ionic species permeability. It is useful as a separator between conductive members in electric and electronic components such as capacitors, capacitors, batteries and the like. Comparative Example 1
- the prepared aramide fibrids, metharamid staple fibers (length: 6 mm) and tetron staple fibers were each dispersed in water to prepare a slurry. These slurries were mixed with fibrid, aramide staple fiber, and staple staple fiber so as to have the compounding ratio shown in Table 2, and sieved with a tappy-type hand-making machine (cross-sectional area: 325 cm 2 ). A product was prepared. Next, this was hot-pressed with a metal calender roll at a temperature of 230 ° C. and a linear pressure of 300 kg / cm to obtain a separator.
