Electrically insulating nanocomposite having semiconducting or nonconductive nanoparticles, use of this nanocomposite and process for producing it

Номер: US20130187099A1

Принадлежит: SIEMENS AG

A cellulose material contains cellulose fibers having an impregnation. Accordingly, the impregnation is made of nanoparticles, in particular BNNT, containing a shell of polymers, in particular PEDOT:PSS. The impregnation forms a type of network that can reduce the specific resistance of the cellulose material due to the electrical conductivity of the network. The cellulose material can thereby be advantageously adapted to corresponding applications with respect to the electrical properties thereof. The cellulose material can thus also be used to electrically insulate transformers, wherein the cellulose material is thereby saturated with transformer oil and an adaptation of the specific resistance of the cellulose material to the specific resistance of the oil leads to improved dielectric strength of the transformer insulation. A method for producing the cellulose material described above contains a suitable impregnation step for the cellulose material.

An umbilical ( 600 ) for the transfer of fluids and/or electric current/signals, particularly between the sea surface and equipment deployed on the sea bed (e.g., in deep waters), is provided. The umbilical contains a plurality of elongated umbilical elements (e.g., two or more), such as a channel element ( 603 ), fluid pipe ( 604 ), electric conductor/wire ( 606 ) (e.g., optic fiber cable), armoring wire, etc., enclosed within an outer sheath (e.g., plastic sheath). The umbilical also contains at least one reinforcing rod ( 607 ) formed from a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix. The present inventors have discovered that the degree to which the ravings are impregnated with the thermoplastic polymer matrix can be significantly improved through selective control over the impregnation process, and also through control over the degree of compression imparted to the ravings during formation and shaping of the rod, as well as the calibration of the final rod geometry. Such a well impregnated rod has a very small void fraction, which leads to excellent strength properties for reinforcing the umbilical elements.
