HEAT CONDUCTIVE MATERIAL - AUTONETWORKS TECHNOLOGIES LTD

Title:

HEAT CONDUCTIVE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2020/080319

Kind Code:

A1

Abstract:

The present invention provides a heat conductive material which has high heat conductivity without significantly deteriorating lightweightness. This heat conductive material contains water and cellulose nanofibers. The heat conductive material is able to contain from 0.1 part by mass to 3 parts by mass (inclusive) of the cellulose nanofibers per 100 parts by mass of water. It is preferable that the cellulose nanofibers have an average aspect ratio of from 180 to 260 (inclusive). This heat conductive material is suitable for use in components for vehicles.
