Beschreibung
Zusammenfassung:	A low density foam material and methods for making such, comprising self-assembled graphene oxide in foam is described having high performance acoustic absorption as well as increased moisture insulation and fire-retardant properties. The graphene oxide material is inserted or distributed within openings of open cell/pore foam material resulting in a novel foam material that has increased acoustic absorption properties. L'invention concerne un matériau en mousse basse densité et des procédés de fabrication de celui-ci, comprenant de l'oxyde de graphène autoassemblé dans de la mousse, présentant une absorption acoustique haute performance ainsi qu'une isolation accrue à l'humidité et des propriétés ignifuges. Le matériau d'oxyde de graphène est inséré ou distribué à l'intérieur d'ouvertures de matériau de mousse à cellules/pores ouvertes, ce qui permet d'obtenir un nouveau matériau en mousse qui présente des propriétés d'absorption acoustique accrues.
