The invention relates to a plastic film with an interference multilayer system applied thereon that comprises at least two layers. Said layers can be obtained by hardening and/or applying thermal treatment to a coating composition containing nanoscale inorganic solid particles having polymerizable and/or polycondensable organic surface groups, thereby forming a layer that is crosslinked by means of the polymerizable and/or polycondensable organic surface groups. The films can be used as an optical laminating film.

Plastic film with a multilayered interference coating

The present invention relates to the use of aerogels as carrier materials for active substances in agriculture and/or veterinary medicine.

The invention relates to an alternative composite mask that is substantially composed of a transparent support film coated with a transparent polymer matrix that contains light-absorbing pigment particles or metal particles having an average particle size dranging between 0.5 and 10 &#x3bc;m.

Composite mask for producing a diffuser

The invention relates to solid or gel-type nanocomposite material which can be polymerised, containing a) 4.9 95.9 wt. % of a soluble polymer; b) 4-95 wt. % of a partially or totally condensed silane selected from the group of epoxyalkoxysilanes, alkoxysilanes and alkylalkoxysilanes, the silane having an inorganic condensation degree of between 33-100% and an organic conversion degree of between 0-95%; c) 0-60 wt. % of an acrylate; d) 0.1-50 wt. % of surface modified nanometric particles selected from the group of oxides, sulphides, selenides, tellurides, halogenides, carbides, arsenides, antimonides, nitrides, phosphides, carbonates, carboxylates, phosphates, sulphates, silicates, titanates, zirconates, aluminates, stannates, plumbates and a mixed oxides; e) 0-50 wt.-% of a plasticizer; f) 0-5 wt. % of a thermal or photochemical cross-linking initiator, sensitizer, auxiliary wetting agent, adhesive agent, antioxidant, stabiliser, coloring agent, photochrome material and thermochrome material in relation to the total weight (dry weight) of the nanocomposite material.

Nanocomposite material for the production of index of refraction gradient films

The present invention relates to a composite material that contains 5 to 97%-vol aerogel particles, at least one binder, and at least one fibre material, the diameter of the aerogel particles being &#x2267;0.5 mm, a process for manufacturing this, and the use thereof.

Composite aerogel material that contains fibres

Interpenetrating organic and inorganic networks with a maximum dimension of 100 mn are produced by: (1) mixing aqueous solutions or dispersions of organic polymers capable of forming polymer networks in aqueous phase, polymer precursors or the mixtures thereof and silicon dioxide components; (2) changing the pH value and/or thermally treating the aqueous solution or dispersion in order to form a gel made of interpenetrating organic and silica gel networks and (3) drying the gel.

Nanoporous interpenetrating organic-inorganic networks

The invention relates to a composite material which has at least one formation comprising fibers and aerogel particles and is characterised in that the fibrous formation contains at least one thermoplastic fibrous material to which the aerogel particles are bound and by which the fibers in the formation are bound together. It also relates to a process for the production of said composite material, and the use thereof.
