METHOD FOR SURFACE MODIFICATION OF A BODY

The invention concerns a method for modification of the surface of a body, especially a film-shaped body, wherein a fibre-containing substance comprising nano-sized polysaccharide fibre particles is dispersed in a medium essentially composed of water and a polar solvent to form a suspension. The sus...

Beschreibung
Zusammenfassung:	The invention concerns a method for modification of the surface of a body, especially a film-shaped body, wherein a fibre-containing substance comprising nano-sized polysaccharide fibre particles is dispersed in a medium essentially composed of water and a polar solvent to form a suspension. The suspension is applied on the surface by a printing method. According to the invention, the viscosity of the suspension is adjusted to a range that is suitable for the printing method by adjusting the fibre concentration of the suspension. The invention concerns also a composition disposable onto the surface of a body, such as a film-shaped body, by a non-contact inkjet printing method. According to the invention, the composition comprises nanocellulose fibres suspended in a medium essentially composed of water and a polar solvent, miscible with water, wherein the concentration of nanocellulose fibres is 0.5 to 1.5 %, preferably 0.5 to 1 %, most preferably about 0.7 %of said composition. L'invention concerne un procédé de modification de la surface d'un corps, notamment un corps en forme de film, une substance contenant des fibres comportant des particules nanométriques de fibres de polysaccharide étant dispersée dans un milieu sensiblement constitué d'eau et d'un solvant polaire pour obtenir une suspension. La suspension est appliquée sur ladite surface par un procédé d'impression. Selon l'invention, la viscosité de la suspension est ajustée à une plage convenant au procédé d'impression par l'ajustement de la concentration en fibres de la suspension. L'invention concerne également une composition pouvant être disposée sur la surface d'un corps, par exemple un corps sous forme de film, par un procédé d'impression à jet d'encre sans contact. Selon l'invention, la composition comprend des fibres nano-cellulosiques en suspension dans un milieu sensiblement constitué d'eau et d'un solvant polaire, miscible à l'eau, la concentration de fibres nano-cellulosiques étant comprise entre 0.5 et 1.5 %, de préférence entre 0.5 et 1 %, et étant idéalement égale à environ 0.7 % de cette composition
