‘VIA CARPATIA Universities of Technology Network named after the President of the Republic of Poland Lech Kaczyński’ contract no. MEiN/2022/DPI/2578, action entitled ‘In the neighborhood – inter-university research internships and study visits’
Novel nonterminal liquid crystalline epoxy resin has been synthesized, and its structure and nature have been de-
termined via nuclear magnetic resonance (NMR) and polarized optical microscopy (POM). Then, it was cured with the use
of 4,4′-diaminodiphenylmethane (4,4′-DDM). The curing process has been investigated via differential scanning calorimetry
(DSC) and infrared spectroscopy (FTIR) methods. Polymerization has been conducted with (1.2 T) and without the presence
of a strong magnetic field. The properties of the obtained polymers have been described using DSC, thermogravimetric
analysis (TGA), scanning electron microscopy (SEM), dielectric spectroscopy (DS) and X-ray scattering studies
(WAXS/SAXS). It has been proved that the magnetic field induces molecular ordering and increases the glass transition
temperature (Tg) by over 20 °C. The obtained ordered polymers are thermally stable up to over 300 °C, undergo vitrification
at slightly elevated temperature (37.5 °C), and their electrical conductivity rises significantly at the transition to an elastic
state, which, among other possibilities, makes them a proper candidate for a smart, lightweight polymers with tuneable prop-
erties by a subtle temperature rise and possibility of tailoring its structure by a magnetic field.
