    摘要: The invention provides novel surface coatings having surface polymer brushes with zwitterionic and antibiotics-conjugated side chains and synergistic anti-fouling and bactericidal properties. The surface coatings may be prepared using highly efficient surface-initiated “living” polymerization. The design of the surface polymer brushes are highly modular, allowing independent tuning of the anti-fouling and bactericidal properties, e.g., by varying the chemical nature of the zwitterionic motif and the antibiotic agent, the chemistry through which the antibiotic agent is conjugated to the polymer side chains, the molecular weight of the polymer brushes (e.g., thickness of coating and density of respective functional motifs), and the spatial arrangement of the respective functional motifs (e.g., homopolymers, block copolymers, random copolymers) to achieve optimal and sustained anti-infection outcome for a given application.

    摘要: The present invention aims to reduce excess scattering in light emitting arrangements. A composition comprising a transparent matrix comprising an anionic organic moiety, and metal cations dispersed in the matrix is disclosed. The anionic organic moiety and the metal cations form an organometallic complex, and wherein the metal cations are capable of forming transparent nano-crystals upon contact with an agent comprising at least one element selected from the group consisting of sulfur and selenium. Also an optical composition comprising a transparent matrix comprising an organic moiety residue, and unmodified nanocrystals is disclosed. Further, a method of preparing an optical composition comprising the steps of: providing a transparent matrix comprising an anionic organic moiety; dispersing metal cations into the matrix; and contacting the organometallic complex with an agent in order to in situ convert at least part of the metal cations into transparent nanocrystals.Preferably the matrix is a silicone or a polysiloxane and silicone rubber mixture.

    摘要: A process for the preparation of a polymer nanoparticle by a photoinduced emulsion polymerization includes preparing an emulsion comprising at least one surfactant, a dispersed phase and a continuous phase. The dispersed phase comprises at least one polymerizable monomer and the continuous phase comprises water and at least one photoinitiator. The at least one polymerizable monomer is polymerized by exposing the emulsion to an electromagnetic radiation having a wavelength so as to induce a generation of radicals from the at least one photoinitiator. The at least one photoinitiator is selected from at least one compound of formula (I)
