    摘要： The present invention relates to biocidal articles. In an embodiment the biocidal article comprises a plurality of polymers having biocidally active groups. The polymers are attached to a surface and may have a polydispersity less than 3. The biocidally active groups may comprise at least one of a quaternary ammonium salt, a quaternary phosphonium salt or a chloroamine. The attached polymers may be any microstructure, topology or composition, such as, a homopolymer, block copolymer, multiblock copolymer, a random copolymer, graft polymer, a branched or a hyperbranched polymer, and a gradient copolymer. The present invention also comprises a process for the preparation of a biocidal article. Embodiments of the process comprise polymerizing radically polymerizable monomers from an initiator attached to a surface, wherein at least a portion of the monomers comprise a group capable of being converted to a biocidally active group, and converting the group to the biocidally active group.

    摘要： A biocidal article, includes a surface including a plurality of polymers covalently attached to the surface. The polymers include biocidal cationic groups. The polymers have a molecular weight distribution or polydispersity less than 3. A grafting density of the polymers on the surface is controlled, average degree of polymerization of the polymers is controlled and repeat units of the polymers are chosen to provide a predetermined charge density arising from the cationic groups. A method of analyzing biocidal activity of biocidal surface agents includes the steps: attaching a plurality of chemical entities to one or more surfaces so that at least one physiochemical property is varied, each of the chemical entities comprising at least one biocidally active component; and exposing the chemical entities to at least one biological agent to determine the effect of the at least one physiochemical property upon biocidal activity. The biocidal activity can, for example, be antibacterial activity or sporicidal activity. The at least one physiochemical property can, for example, be varied in a preferably systematic manner.

    摘要： Performance and reliability of microelectromechanical system (MEMS) components enhanced dramatically through the incorporation of protective thin film coatings. Current-generation MEMS devices prepared by the LIGA technique employ transition metals such as Ni, Cu, Fe, or alloys thereof, and hence lack stability in oxidizing, corrosive, and/or high temperature environments. Fabrication of a superhard, self-lubricating coating based on a ternary boride compound AlMgB14 is described in this letter as a potential breakthrough in protective coating technology for LIGA microdevices. Nanoindentation tests show that hardness of AlMgB14 films prepared by pulsed laser deposition ranges from 45 GPa to 51 GPa, when deposited at room temperature and 573 K, respectively. Extremely low friction coefficients of 0.04-0.05, which are thought to result from a self-lubricating effect, have also been confirmed by nanoscratch tests on the AlMgB14 films. Transmission electron microscopy studies show that the as-deposited films are amorphous, regardless of substrate temperature; however, analysis of FTIR spectra suggests that the higher substrate temperature facilitates formation of the B12 icosahedral framework, therefore leading to the higher hardness.
