    摘要： A printing device comprising a polymer element capable of switching from an initial state to a final state when subjected to an event, the initial state and the final state being selected from an hydrophilic state and an hydrophobic state provided that the initial state differs from the second state, wherein said polymer element is impregnated with a print fluid, and a controller adapted to generate the event producing the switch of the polymer element, provided that the event is an optical, a thermal or a chemical event, wherein the controller is adapted to generate the event producing the switch of the polymer element on a localized zone and on a internal zone delimited by the localized zone, in order to form a fluid drop at the surface of the polymer element.

    摘要： The present invention relates to a device for controlling fluid movements. The device includes a fluid guiding device, and a fluid moving device which includes polymers whose hydrophilic and hydrophobic properties can be selected under the action of an external force. The fluid moving device comprises a plurality of polymer elements whose hydrophilic and hydrophobic properties can be selected. The elements are arranged along the guiding device and at least one actuating unit is used to generate the external force.

    摘要： The present invention relates to a method for preparing a hybrid aluminosilicate polymer and the polymer resulting from this method. Said method consists in treating an aluminum halide with a mixture of at least one silicon alkoxide only having hydrolyzable substituents and at least one silicon alkoxide having a non-hydrolyzable substituent, with an aqueous alkali, in the presence of silanol groups, aluminum concentration being maintained at less than 0.3 mol/l, the Al/Si molar ratio being maintained between 1 and 3.6 and the alkali/Al molar ratio being maintained between 2.3 and 3; and then in stirring the resulting mixture at ambient temperature in the presence of silanol groups for long enough to form the hybrid aluminosilicate polymer.
