Prepatation and characterization of poly(ether-block-amide)/metal-salt antistatic composites

Abstract

Polyether diol and end-capped diisocyanates were first employed in a step-growth addition polymerization with amidogen terminated Polyamide-6 to synthesis segmented poly(ether-block-amide) (APEBA) with organized molecular chain structure. Colorless salts were mixed with the copolymers to develop solid polymer electrolyte (SPE). Chemical structures of composites were characterized by infrared-spectroscopic analysis (FTIR). Thermal behaviors were studied by differential scanning calorimetery (DSC) and thermo gravimetric analyzer (TGA). The APEBA elastomer showed excellent antistatic properties in decreasing the surface resistivity (Rs), which decreased to 107.78Ω cm−2 when the doping-salt content approaches 2.5 phr. Also, Rs exhibits humidity-independency and enduring-existence.
