  • Patent number: 6861103
    Abstract: Nitroxide mediated free radical polymerization of vaporized vinyl monomers, including acrylic acid (AAc), styrene (St), N-2-(hydroxypropyl)methacrylamide (HPMA) and N-isopropyl acrylamide (NIPAAm), on silicon wafers is demonstrated. FTIR, ellipsometry and contact angle goniometry were used to characterize the chemical structures, thickness and hydrophilicity of the films. The growth of film is linearly proportional to its reaction time, leading to the easy and exact control of polymer film thickness from nanometers to submicrons. The capability of polymerizing various monomers allows us to fabricate various functional polymer brushes. The reversible thermo-responsiveness of a 200 nm thick grafted poly(NIPAAm) film in aqueous solution is demonstrated with over 50% change in thickness at its lower critical solution temperature. A tri-block copolymer of poly(AAc)-b-polySt-b-poly(HPMA) is successfully synthesized, proving the renewability of TEMPO-mediated polymerization at vapor phase.

  • Patent number: 6426124
    Abstract: A processed fiber is used to distribute energy from an electromagnetic (EM) energy source to a material in which the fiber is embedded. The electromagnetic energy source supplies electromagnetic energy to the fiber and the fibers emit portions of the EM energy along the length of the fiber. The sealant material absorbs a quantity of the electromagnetic energy sufficient to cure the sealant material and propagates excess electromagnetic energy through the sealant material without significant additional absorption. This prevents the sealant material from over-curing. Additionally, a fully cured material can be used to generate thermal energy and thereby serve as a heat blanket that can be used to de-ice aircraft.

  • Patent number: 6274203
    Abstract: Artificial leather can be produced, without using any organic solvent, by coating or impregnating a fibrous base material to be formed into artificial leather with a polymer solution in the form of an aqueous emulsion, in which the polymer exhibits elasticity when it is solidified and adhered to the base material; and then solidifying and adhering or fixed, in the fibrous base material, the polymer solution contained in the base material using a combination of wet heat (using the heat of water vapor) and microwave heating. Therefore, the method is not harmful to the environment and permits the reduction of the degree of migration as compared with the conventional methods in which the solidification and adhesion or fixation are performed by dry heating while making use of hot air.

  • Patent number: 5888591
    Abstract: Provided are methods for forming a fluorocarbon polymer thin film on the surface of a structure. In one method, a monomer gas is exposed to a source of heat having a temperature sufficient to pyrolyze the monomer gas and produce a source of reactive CF.sub.2 species in the vicinity of the structure surface. The structure surface is maintained substantially at a temperature lower than that of the heat source to induce deposition and polymerization of the CF.sub.2 species on the structure surface. In another method for forming a fluorocarbon polymer thin film, the structure is exposed to a plasma environment in which a monomer gas is ionized to produce reactive CF.sub.2 species. The plasma environment is produced by application to the monomer gas of plasma excitation power characterized by an excitation duty cycle having alternating intervals in which excitation power is applied and in which no excitation power is applied to the monomer gas.
