Abstract

Hybrid interpenetrating networks (IPN) in the form of free-standing nanomembrane with unprecedented macroscopic size and characteristics were synthesized using the spin coating technique. Hybrid IPNs in the bulk state have the combined advantages of polymers, with the physical properties of glass. Self-floating nanomembranes were deposited onto a silicon wafer and examined by atomic force microscopy. Reactive formulations containing both the organic and inorganic precursors were prepared and diluted in chloroform. A 100-nm-thick layer of polyvinyl phenol was spin-coated onto a clean silicon wafer. SEM analysis reported that the pores of Anodisc were fully covered with the nanofilm without any defects or cracks. The self-supporting nanofilms floating in ethanol were observed to be very flexible, robust, and can easily be folded into small shapes.
