Abstract

Abstract:

The effective thermal conductivity(κ_eff)of hollow microsphere-filled polypropylene(PP)composite was
measured by using a thermal conductivity instrument，and the equation of efective thermal conductivity published
in the previous paper was preliminarily verified．The results show that the estimated values of κ_effare in good agree—
ment with the measured ones except few points，and that κ_effdecreases roughly linearly with the volume fraction(φ_f)
of hollow microsphere when φ_f≤20%，while decreases slightly with the increase in particle diameter at lower φ_f．

Key words: hollow microsphere, polypropylene, polymer composite, heat-transfer model, thermal conductivity, experimental verification
