Title
(EN) POLYURETHANE FILM COMPRISING GRAPHENE AND PREPARATION PROCESS THEREOF.
(FR) FILM DE POLYURÉTHANE COMPRENANT DU GRAPHÈNE ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ
Abstract
(EN)
A polyurethane film comprising a polyurethane resin and graphene, wherein the graphene is present in an amount of 1 to 30% by weight on the total weight of the film and consists of graphene nano-platelets, wherein at least 90% has a lateral dimension (x, y) of 50 to 50000 nm and a thickness (z) of 0.34 to 50 nm, wherein the lateral dimension is always greater than the thickness (x, y > z), wherein the C/O ratio is ≥ 100:1, and a preparation process thereof.
(FR)
La présente invention concerne un film de polyuréthane comprenant une résine de polyuréthane et du graphène, le graphène étant présent en une quantité de 1 à 30 % en poids sur le poids total du film et étant constitué de nano-plaquettes de graphène, au moins 90 % ayant une dimension latérale (x, y) de 50 à 50 000 nm et une épaisseur (z) de 0,34 à 50 nm, la dimension latérale étant toujours supérieure à l'épaisseur (x, y > z), le rapport C/O étant ≥ 100/1. L'invention concerne également un procédé de préparation du film de polyuréthane.
