Abstract
Conductive paints of polyaniline (PANT)/dodecyl benzene sulfonic acid (DBSA) composited with polystyrene (PS), polyester (PET) and polyurethane (PU) resin were prepared through a facile blending method. The extraction of PANI/DBSA from the aqueous reaction mixture was done by using a mixture of toluene and methyl ethyl ketone (MEK) (toluene : MEK=1: 1 v/v), Then, the electrical, thermal stability and tensile properties of the prepared conductive PANI/DBSA composite films were evaluated. Almost all of the PANI/DBSA-PS, -PET and -PU composite films were found to possess relatively good conductivity and low surface resistivity for an electrostatic discharge (ESD) even at low PANI/DBSA content. Even when the PANI/DBSA content in the PANI/DBSA-PS and - PET composite was 2.5 wt %, the electrical conductivity and surface resistivity were found to be 3.92 X 10 - 4 Scm -1 , 8.51x10 6 Ωcm -2 and 4.62 X 10 - 2 Scm -1 , 7.22 X 10 4 Ωcm -2 , respectively. Additionally these composite films exhibited good transparency. The highest conductivity (3.28 X 10 -1 Scm -1 ) of the composite films was obtained when the PANI/DBSA content in PANI/DBSA-PS composite was 25 wt%. PANI/DBSA-PS composite film possessed the best thermal stability and the PANI/DBSA-PU composite films showed the lowest thermal stability of all evaluated samples. On the other hand, PANI/DBSA-PET composite films possessed the most elasticity when the PANI/DBSA contents were 10 and 20 wt%. However, PANI/DBSA-PU composite film possessed the most elasticity when the content was 5 wt %. PANI/DBSA-PS composite films possessed the lowest elasticity.
