Influence of mixing conditions on rheological behavior and electrical conductivity of polyamides filled with carbon black

摘要: The introduction of carbon black in a polyamide matrix allows one to obtain conductive materials because the formation filler network. Resulting electrical properties depend, among others, on processing conditions. In first part, we investigate influence mixing conditions (rotor speed, temperature, time) conductivity. Then, second try characterize conducting network by rheological measurements and establish relationships between parameters properties. For that purpose, propose perform successive strain sweep experiments at constant frequency, from 0.5 100%, then 100 0.5%, finally, again, 100%. Between two sweeps, observe drop moduli values can be attributed breakdown A clear relationship is established compounds. Moreover, presentation data permits rank samples according strength
