Researchers of Amirkabir University of Technology have created a kind of polymers which can be applied in medical industry.

According to an ISCA report, the result of the research, carried out by Yaseen Kaykha and led by Mehdi Rafizadeh, has been published in Materials Chemistry and Physics.

Based on the research, “functionalized poly(butylene succinate) (PBSS), prepared via sulfonation of poly(butylene fumarate) (PBF), was successfully applied as a novel polymeric dopant for polyaniline (PANI).”

“To obtain a conductive and degradable PANI:PBSS complex, the aniline monomers were polymerized in the presence of a negatively charged polyelectrolyte template (PBSS).”

“The prepared polymers were characterized through proton nuclear magnetic resonance (1HNMR), Fourier transform infrared (FT-IR), ultraviolet–visible spectroscopy (UV–visible spectroscopy), scanning electron microscopy (SEM), differential scanning calorimeter (DSC), X-ray diffraction (XRD) and electrical conductivity measurements. The hydrolytic degradation of PANI:PBSS was also investigated based on FT-IR analysis and weight loss.”

“Based on the results, the semi-crystalline structure of PBF was changed to an amorphous structure in PBSS and PANI:PBSS. The PANI morphology in the presence of the small dopant (HCl) was granular, while it changed into a fibrillar shape in the presence of the macromolecular dopant.”

“The electrical conductivity of PANI:PBSS (28.6 S/m) was slightly smaller than that of the HCl-doped PANI (48.4S/m). The alkaline solution could hydrolytically degrade PANI:PBSS and after 10 days, a weight loss of 45% was observed.”
