A new class of silicone monomers, providing transparent materials and imparting hydrophilic properties have been developed. These materials are incorporated into ophthalmic devices such as soft and rigid gas permeable (RGP) contact lenses. These new silicone monomers include Polyhedral Oligomeric Silsesquioxane (POSS) with two polymerizable groups and six organofunctional groups. These types of structures incorporate at least two available sites for polymerization allowing for the incorporation of the silsesquioxane cage into the backbone of a macromolecule. Additional functional sites allow the design of specific chemical features which address needed material properties.

Articles such as filter media, which include dendrimers and/or other components, are provided. The filter media may further include a water repellant (e.g., a fluorinated species) to impart desirable properties to the media such as high water repellency. The filter media may also have a high efficiency as a function of pressure drop (i.e., high gamma values). In some embodiments, the filter media includes a fiber web which may be formed of various components such as glass fibers. The fiber web can also include additional components such as synthetic fibers, binder components, as well as other additives. The media may be incorporated into a variety of filter element products.

The present invention discloses a method of preparing a terpolymer-doped polyaniline super-hydrophobic composite anticorrosive paint. The method includes: firstly by adopting solution polymerization, stirring a hydrophilic vinyl monomer, a fluorine-containing acrylate monomer and an oil-soluble initiator in a solvent evenly and carrying out a reaction for a period of time, then adding a functional acrylic monomer or long-chain acrylate monomer as a third monomer for further reaction for a period of time to obtain a fluorine-containing terpolymer surfactant; then mixing the fluorine-containing terpolymer surfactant with an aniline monomer and an oxidant evenly, and carrying out a reaction for a period of time to obtain super-hydrophobic polyaniline; and finally dispersing the prepared super-hydrophobic polyaniline evenly in a resin matrix to prepare the polyaniline super-hydrophobic composite anticorrosive paint with an excellent anticorrosive performance.
