Anisotropic linear thermal expansivity of poly(ether-ether-ketone)

High performance nanocomposites for tribological applications: Preparation and characterization

“…Recently, we have demonstrated the improvement in thermal, dynamic mechanical, and wear properties of PEEK by incorporating micron size Al 2 O 3 particles [1,2,19]. The dynamic mechanical properties of PEEK composites have been found to increase with increasing Al 2 O 3 [2] or AlN [20] particles both below and above the glass transition temperature of PEEK.…”

Novel high performance Al2O3/poly(ether ether ketone) nanocomposites for electronics applications

“…The detailed procedure of the CTE measurement was described elsewhere [20]. The annealed sample was heated under pressure of 50 mN from 30 to 250°C at a heating rate of 5°C/min in argon atmosphere.…”

Dramatic Effects of Scalable SNN‐Assisted Melt Dispersion on Thermal Conductivity and Coefficient of Thermal Expansion of Nanocomposites

“…CTE values of polymers (2-10 Â 10 À5 8C À1 ) are much higher than those of metals (5-10 Â 10 À6 8C À1 ), and those of metals are higher than those of ceramics (2-5 Â 10 À6 8C À1 ). [3][4][5] These large CTE mismatches lead to accumulation of thermal stress at contact interfaces during both packaging and device performance, which triggers component failure by, for example, warpage and rupture. Therefore, low CTE is also an important thermal parameter in polymeric composites used in electronic packaging.…”
