A new material with hydrophobic-hydrophilic properties is obtained based on ultrathin poly(3-hydroxybutyrate) (PHB) fibers modified with poly(2-hydroxyethyl methacrylate). The supramolecular structure of the samples is investigated by structurally dynamic methods: scanning electron microscopy, differential scanning calorimetry, and electron paramagnetic resonance. The equilibrium-kinetic characteristics of water sorption by the material are determined. Evidence is obtained by the method of 1H NMR (proton nuclear magnetic resonance spectroscopy) for the chemical modification of the PHB surface due to the participation of its terminal groups in the transesterification reaction of 2-hydroxyethyl methacrylate. |
