Laminar body to make roofs of greenhouse which comprises at least a laminar layer and a Polymer Matrix and Titanium dioxide nanoparticles dispersed in the polymer Matrix； cultivation method； use of this body； Greenhouse； and a Master Mix.
The invention relates to a laminar body for making greenhouse roofs, comprising at least one laminar layer, which defines at least one main surface of the laminar body and comprises a polymer matrix and nano-particles of titanium dioxide TiO2 in the anatase and/or rutilium form, dispersed in the polymer matrix. The nano-particles have dimensions not greater than 100 nm. The titanium dioxide is present with a concentration in weight of between ′30 and 1500 ppm in relation to the polymer matrix. The invention also relates to a method of greenhouse cultivation and the use of the laminar body according to the invention for making greenhouse roofs. The invention also relates to a greenhouse having a roof comprising at least one laminar body according to the invention and to a masterbatch for making a laminar layer of a laminar body according to the invention.<；p>；Un cuerpo laminar para hacer tejados de invernadero que comprende al menos una capa laminar, que define al menos una superficie de dicho cuerpo laminar y que comprende una matriz de polí；mero y nanopartí；cula de dió；xido de titanio TiO2 en la forma de anatasa y/o de Rutilio, disperso en la matriz de polí；mero, dichas nanopartí；culas teniendo dimensiones no mayores de 100 nm, el dió；xido de titanio estando presente en una concentració；n en peso de entre 30 y 1500 ppm en relació；n con la matriz de polí；mero.<；/p>；
