There is provided a process for producing an organic PTC thermistor including the steps of: At least one of the mixing step, the layer-forming step and the laminating step is conducted under reduced pressure. An organic PTC thermistor obtained by the production process is also provided.

Organic PTC thermistor and production

The present invention provides an electrolytic capacitor manufacturing method capable of manufacturing an electrolytic capacitor having the PTC function as easy as possible. A main electrode layer in a cathode is formed so as to have the PTC function. Different from a conventional electrolytic capacitor manufacturing method of connecting a PTC thermistor to a capacitor element to give the PTC function to an electrolytic capacitor so that an electrolytic capacitor manufacturing process is complicated and the number of manufacturing processes is increased by the amount corresponding to the PTC thermistor connecting process, the process of connecting the PTC thermistor to the capacitor element is unnecessary. Consequently, complication of the electrolytic capacitor manufacturing process and increase in the number of manufacturing processes caused by the PTC thermistor connecting process can be prevented.

Electrolytic capacitor and method of manufacturing the same

The invention provides an organic positive temperature coefficient thermistor provided with a pair of mutually opposing electrodes and a thermistor element with a positive resistance-temperature characteristic situated between the pair of electrodes, wherein said thermistor element contains a cured body derived from a mixture comprising an epoxy resin, a curing agent and conductive particles, and there is included in the epoxy resin and/or curing agent a compound which imparts flexibility to the cured body.

Organic positive temperature coefficient thermistor

In an organic PTC thermistor comprising a thermistor body comprising a high-molecular weight organic compound-containing matrix and metal particles, conductive non-metallic fines, typically carbon black, are attached to surfaces of the metal particles. The device has a low room-temperature resistance and a high change rate of resistance, and prevents degradation of its performance during storage under hot humid conditions.

Organic PTC thermistor

In an organic PTC thermistor comprising an organic polymer matrix and conductive metal particles dispersed therein, the conductive metal particles are pretreated with an organic material which is different from the organic polymer matrix, does not covalently bond with the conductive metal particles, and is not compatible at a molecular level with the organic polymer matrix so that an organic material layer covers surfaces of conductive metal particles whereby the stability of thermistor performance is improved.

Organic PTC thermistor and making method

In an organic PTC thermistor comprising a matrix of at least two high-molecular weight compounds, a low-molecular weight organic compound, and conductive particles having spiky protuberances, a thermoplastic elastomer is contained in the matrix whereby the thermistor is improved in reliability and performance stability.

The invention aims to provide an organic PTC thermistor having a lower operating temperature than prior art organic PTC thermistors and exhibiting improved characteristics. The object is attained by an organic PTC thermistor comprising a polymer synthesized in the presence of a metallocene catalyst and conductive particles having spiky protuberances.

Organic positive temperature coefficient thermistor and making method

The organic positive temperature coefficient thermistor of the invention comprises a thermosetting polymer matrix, a low-molecular organic compound and conductive particles, each having spiky protuberances, and so can have sufficiently low room-temperature resistance and a large rate of resistance change between an operating state and a non-operating state. In addition, the thermistor can have a small temperature vs. resistance curve hysteresis with no NTC behavior after resistance increases, ease of control of operating temperature, and high performance stability.

The invention provides an organic positive temperature coefficient thermistor comprising at least two polymer matrices, a low-molecular organic compound and a conductive particle having spiky protuberances. For the polymer matrices, at least two thermoplastic polymer matrices having varying melting points or at least one thermoplastic polymer matrix and at least one thermosetting polymer matrix are used. It is thus possible to provide an organic positive temperature coefficient thermistor which has sufficiently low room-temperature resistance and a large rate of resistance change between an operating state and a non-operating state, and can operate with a reduced temperature vs. resistance curve hysteresis, ease of control of operating temperature, and high performance stability.
