Abstract
A composition including a binder and a variable thermal conductivity material satisfying a conditional expression 1, wherein a content of the variable thermal conductivity material is from 300 parts by weight to 10,000 parts by weight with respect to a content of 100 parts by weight of the binder: κmax/κ25≥1.2 [conditional expression 1] (wherein, κ25 represents a thermal conductivity at 25° C., and κmax represents the maximum value of a thermal conductivity at 200° C. or 500° C.).
Claims15
A composition comprising:
- a binder and
- a variable thermal conductivity material satisfying a conditional expression 1,
- wherein a content of said variable thermal conductivity material is from 300 parts by weight to 10,000 parts by weight with respect to a content of 100 parts by weight of said binder:
- κmax/κ25≥1.2 [conditional expression 1]
- wherein, κ25 represents a thermal conductivity at 25° C., and κmax represents the maximum value of a thermal conductivity at 200° C. or 500° C.,
- wherein the thermal conductivity material comprises at least one oxide selected from the group consisting of
- metal oxides represented by MyOz, and
- composite metal oxides represented by AxMyOz,
- in which
- A represents at least one element selected from the group consisting of alkali metals, alkaline earth metals, Sc, Y and rare earth elements,
- M represents at least one metal element selected from titanium, vanadium, manganese, cobalt, or nickel,
- x, y and z each independently represent a positive number, and
- wherein the thermal conductivity material comprises particles having a median diameter from 10 nm to 100 μm.
