    摘要: The invention concerns the field of chemistry and relates to oil-modified PTFE solid lubricants which can be used as additives for example or form the base material for oil-PTFE dispersions, oil-PTFE grease, or oil-PTFE lubricant pastes that can be used in special lubricants or as special lubricants and in solid lubricants or as solid lubricants for oil-free transmissions for example in the fields of mechanical engineering, automotive engineering, and aerospace. The aim of the invention is to provide oil-modified PTFE solid lubricants which can be handled and metered more easily and which are readily further processable and to provide a simple and inexpensive method for producing same. This is achieved by a method for producing oil-modified PTFE solid lubricants, wherein modified PTFE micropowder with at least perfluoralkyl-(peroxy-)radicals and an oil or an oil mixture, which has olefinically unsaturated double bonds, are mixed at a mass ratio of modified PTFE micropowder to oil or oil mixture of 100 to maximally 10 and reactively converted under mechanical stress with residence times of

    摘要: The invention relates to a physical self-organizing hydrogel system for biotechnological applications composed of a non-covalent network on the basis of a protein-ligand interaction, comprising a tetrameric protein as a protein and biotin or one of the derivatives thereof as a ligand, wherein biotin or one of the derivatives thereof is covalently conjugated to an end of a polymer chain of a linear or multi-arm synthetic polymer or of a single- or double-strand oligonucleotide and wherein the solid content in relation to the entire hydrogel is at least 3% and the conjugates are cross-linked by the tetrameric protein. In the hydrogel system, there is a mixture ratio as a molar equivalent ratio between the protein and the number of terminal biotinylated ends of the polymer chains in the biotin-polymer conjugate of 1:2 to 1:8. The hydrogel formation occurs with controlled kinetics on the basis of a protein-ligand interaction.
