摘要:
The invention relates to a titanium oxide-based polymer composition. The inventive composition comprises a TiOx(OH)y(H2O)z(x+y+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibers having a periodicity which is deduced from the spacing between said fibers, of between 3.5 Å and 4 Å. Each fiber comprises TiO6octahedrons and each TiO6octahedron shares two opposite edges with two adjacent octahedrons (2×2.92 Å) in order to form infinite chains which develop along the axis of a fiber. According to the invention, two adjacent chains form double lines as a result of the shared edges (2×3.27 Å). The inventive polymer is suitable for use as a photosensitive element in a photovoltaic cell, such as a sunscreen for a window.

The invention relates to a titanium oxide-based polymer composition. The inventive composition comprises a TiOx(OH)y(H2O)z(x+y−+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibers having a periodicity which is deduced from the spacing between said fibers, of between 3.5 Å and 4 Å. Each fiber comprises TiO6octahedrons and each TiO6octahedron shares two opposite edges with two adjacent octahedrons (2.times.292 Å) in order to form infinite chains which develop along the axis of a fiber. According to the invention, two adjacent chains form double lines as a result of the shared edges (2.times.3.27 Å).

摘要:
The invention relates to a process for the extrusion of thermoplastic polymers having acid ionic groups.The process consists in preparing a mixture composed of a thermoplastic polymer having acid ionic groups and a plasticizer, in extruding the mixture obtained to form a film, then in washing the film obtained in aqueous medium to remove said plasticizer(s). The plasticizer is chosen from non-volatile compounds which are stable with respect to the ionic groups of the polymer, which are soluble in water or in solvents that are miscible with water, said plasticizers being chosen from the compounds that react with the ionic group of the polymer via formation of a weak bond of the hydrogen bond-type, and the compounds that react with the ionic group of the polymer via formation of a strong bond, of the ionic bond-type.
