high thermal conductivity in amorphous polymer blends by engineered interchain interactions - polymer blends
Thermal conductivity is an important performance of the polymer because it often affects the reliability of the product (
Electronic packaging, for example)
Hot interface material for example)
And/or manufacturing costs.
However, the thermal conductivity of the polymer is mainly within a relatively narrow range (0. 1–0. 5 W m−1 K−1)
It is largely unknown.
Here we show that a mixture of two polymers with high compatibility and appropriately selected linker structures can produce a heat net with density and uniform distribution.
Sharp increase in cross
The plane thermal conductivity was observed under these conditions, reaching more than 1.
M-1 K-1 in typical spin
Cast polymer hybrid films with nano-thickness are about an order of magnitude larger than other amorphous polymers.
