    摘要: The present invention relates to highly porous polymeric materials comprising covalently grafted biologically active species. The invention also relates to a process for the preparation of highly porous materials comprising functional monomers capable of grafting to a biologically active molecular species comprising the steps of: (a) preparing an emulsion composition comprising a droplet phase and a continuous phase and containing monomers, (b) curing the emulsion and (c) optionally removing the water/droplet phase. The invention further relates to a process for grafting biologically active species to such a highly porous polymeric material comprising the steps of: (i) exposing the highly porous material to a solution of the biologically active species in a suitable solvent medium, (ii) optionally adding an activating agent, (iii) optionally heating, and (iv) rinsing the porous material with solvent medium to remove non-grafted species. The highly porous polymeric materials comprising covalently grafted biologically active species can be used e.g. as a heterogeneous catalyst, in biosensors, for chromatography, in biomedical devices and in implants.

    摘要: The invention relates to a new process for the preparation of nano-structured and/or nano-porous surfaces, coatings having a nano-structured and/or nano-porous surface and articles comprising said coatings. The invention also relates to the use of coatings according to the invention, in particular as anti-reflective coatings. The process for the preparation of the surface nano-structured and/or nano-porous coatings is a process comprising the steps of: a) applying a mixture to a substrate which mixture comprises: i) reactive nano-particles; ii) at least one solvent; iii) optionally a compound having at least one polymerisable group, in an amount that results in an increase in the transmission of at least 0.5%, for at least part of the electromagnetic spectrum between 400 and 800 nm, after the mixture has been applied and cured on a transparent substrate, in comparison with the same substrate without a coating; b) inducing crosslinking and/or polymerisation in the mixture applied to the substrate.

    摘要: The invention provides a sol-gel process for preparing a mixture of metal-oxide-metal compounds wherein at least one metal oxide precursor is subjected to a hydrolysis treatment to obtain one or more corresponding metal oxide hydroxides, the metal oxide hydroxides so obtained are subjected to a condensation treatment to form the metal-oxide-metal compounds, which process is carried out in the presence of a catalyst which comprises a labile protecting group (P9) and a base (B) which are covalently linked, whereby the covalent link between the protecting group and the base is cleavable by exposure to an external stimulus, and wherein the base released after exposure to such external stimulus is capable of catalyzing the condensation of the metal-hydroxide groups that are present in the metal oxide hydroxides so obtained.
