Abstract

A study was conducted for the fabrication of large nanomembranes by radical polymerization of multifunctional acrylate monomers. The study used a precursor containing a higher amount of the double-bond moiety and a precursor mixture containing a rigid molecular backbone. Thin layers of poly(styrene-4-sulfonic acid) was formed on Si-wafer by spin-coating, used as water-ethanol soluble sacrificial layers. The study observed a solvent-dependent change in urethanenanomembrane and used acetone as solvent. The study found that the polymerization is necessary for the fabrication of stable acrylate nanomembrane with large size. The study examined the microscopic morphologies by scanning electron microscopy after transfer of the nanomembrane onto anodized aluminum oxide (AAO) substrate. Robust nanomembranes were fabricated from a variety of polymer precursors including organic, inorganic, and organic-inorganic components.
