The study aim was the synthesis and characterization by thermal and structural properties of nanofibers, obtained by electrospinning using styrene-butadiene block-copolymers (SBS) and styrene-isoprene block-copolymers (SIS), as well as their composites with isofural [1].
In the first step, styrene-butadiene block-copolymers (SBS) and styrene-isoprene block-copolymers (SBS) were obtained by anionic sequential polymerization. The reactions were carried out in cyclohexane solution through a three-stage process and were initiated with n-butyl lithium. In the second step, polymer composites with antibacterial properties were obtained, using the synthetized thermoplastic elastomers and isofural in tetrahydrofuran solution [2].
The polymeric composites with antibacterial properties obtained from thermoplastic elastomers and isofural were used for the manufacture of nanofibers by electrospinning (Figure 1 and Figure 2).
The polymer nanofibers manufactured by electrospinning [3] were characterized by ATR-FTIR analysis, Differential Scanning Calorimetry (DSC), and Thermo-gravimetric Analysis (TGA).
The results indicated that the nanofibers obtained from composites of thermoplastic elastomers and isofural have a corresponding thermal stability. The thermal decomposition started after 330 °C in the case of SBS and after 300 °C in the case of SIS.
