Dataset of "Preparation and 29Si NMR Characterization of Hybrid Organic–Inorganic Fibrous Materials"

Hybrid organic–inorganic fibrous materials represent a promising class of new functional materials. This study focuses on the preparation of nonflammable submicron- to nanoscale composite fibrous mats via electrospinning, with an emphasis on processing parameters, material stability, and potential applications. In this study, the hybrid fibers were prepared using TEOS-based sol–gel systems modified with polyvinylpyrrolidone (PVP) to control viscosity and stabilize the spinning suspension. Two spinning solutions compositions, TB (TEOS composition B) and TD (TEOS composition D), were formulated with different ethanol content and acid catalyst ratios. The TD type solution, with higher ethanol content, demonstrated superior fiber formation and thermal stability. Fibers based on SiO₂ containing Si and conductive glass particles were produced through various milling and polymer-assisted electrospinning techniques, and structurally characterized with XRF, XRD, XPS, in both liquid high resolution 29Si hr-NMR and solid state 29Si ss-NMR. The results provide insights into tunability of fiber morphology, porosity, and conductivity, demonstrating their versatility for advanced use.
