摘要:
An appearance-modifying device (10; 30), for modifying the visual appearance of a surface covered thereby, comprising: first (11) and second (12) oppositely arranged optically transparent substrates; a spacer structure (13; 32) spacing apart en the first (11) and second (12) substrates in such a way that a space between the first (11) and second (12) substrates is divided into a plurality of cells (15, 16; 31a-c). The appearance-modifying device further has, in each cell (15, 16; 31a-c), an optically transparent fluid (19) having a plurality of particles (20) dispersed therein, the particles being moveable in the fluid (19) through application of an electric field; and first (17a, 18a; 33) and second (17b, 18b; 32) electrodes arranged to simultaneously, by application of a voltage across the electrodes, control a distribution of the particles (20) within each of a plurality of the cells (15, 16; 31a-c) from a first, dispersed state in which an appearance of the surface covered by the appearance-modifying device is determined by optical properties of the particles (20), to a second state in which the particles (20) are concentrated adjacent to at least one of the first (17a, 18a; 33) and second (17b, 18b; 32) electrodes in such a way that the appearance-modifying device (10; 30) becomes optically transparent.

摘要:
A dual-layer coating for application in a steam-generating device is disclosed. A impermeable first layer thermally insulates the heated surface, while a second, porous layer enlarges the contact area, leading to an efficient conversion of liquid into vapor.
摘要:
A sol-gel coating composition comprising fluoropolymer particles is disclosed. The fluoropolymer particles are distributed homogeneously in the coating, leading to scratch-resistant anti-stick and low-friction coatings that are suitable, for example, for electrical and non-electrical domestic appliances.
摘要:
A sol-gel material with metal particles which can be used as a conductive adhesive for systems that have a high operating temperature is disclosed. The material is especially suitable for appliances equipped with a flat heating element, such as steam irons.

摘要:
In a display device comprising a first substrate having at least one transparent, first picture electrode of a first material, a second substrate comprising at least one second picture electrode of a second material which, jointly with the picture electrode on the first substrate and an intermediate opto-electronic material, defines a pixel, and means for supplying electric voltages to the picture electrodes, the work function between the two picture electrodes is decreased in that at least one of the picture electrodes is coated with at least one layer of conducting material, or a layer of a material comprising a dipole.
摘要:
Disclosed is a layer for use in a domestic appliance, based on a sol-gel precursor. This layer can be obtained by screen-printing and comprises an organosilane compound. The layer is obtained from a concentrated pre-polymerized sol-gel precursor. The layer can be used as an insulating layer or as a conductive layer in a heating element. Furthermore, the layer can be used for decorative purposes.
