77Production and investigation into microstructure and physical properties of Polyamide6 Polyaniline fibres Kamran Zarrini K zarrini@tx iut ac ir Date of Submission 2015 Department of Textile Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree MSc Language Farsi Supervisor Prof M Youssefi youssefi@cc iut ac irAbstractElectrical conductive Fibers and textile structures have applications in several industrial fields like sensors dyeelimination from wastewater anti electrostatic materials plastic welding electromagnetic sheilding antibacterial and anti dust fabrics They also have military application in smart clothes for data transfer Polyaniline is an electro conductive polymer with high thermal and chemical stability in the conductive form Sopolyaniline is a suitable polymer for the above mentioned applications The main aim of this project is productionand characterization of hybrid polyamid6 polyaniline fibers by wet spinning technique Phase diagram ofpolyamide 6 formic acid water was studied Cloud point and gelation point binodal and spinodal region ofpolyamide6 in formic acid as solvent and water as non solvent were calculated and phase diagram was ploted Regarding the phase diagram a volume combination of 17 58 and 25 of water formic acid and polyamid6was chosen in the solid liquid missibility area as the suitable wet spinnig solution Polyaniline was added tospinning solution with several ratios of 0 10 20 30 w w to polyamid6 and wet spinning was carried out Results showed that the combination of formic acid water is the best solvent system for PA6 spinning Breakingstrength of the fibers contained 30 20 10 and 0 polyaniline was 15 06 17 60 19 03 and 22 96 Mpa respectively Therfore breaking strength of the hybrid fibers was decreased with increasing the ratio ofpolyaniline With the increase in polyaniline ratio the breaking strain of the hybrid fibers showed a remarkabledecrease and the modulus of the fibers was increased Conductivity of the hybrid fibers contained 0 10 20 and 30 polyaniline was 4 96 10 6 2 91 10 4 2 65 10 3 and 7 94 10 3 respectively As it was observed theconductivity of the fibers containd 30 20 and 10 polyaniline was increased 1600 534 and 59 timescompared to the fibers contained 0 polyaniline Keywords Polyamide 6 Polyaniline Fibers Phase diagram Conductivity
