Abstract: The invention relates to a method for preparing a biodegradable polyester foam involving: mixing polyester in the form of a molten mass with a nanocharge consisting of organomodified clay; dispersing the latter in the polyester molten mass, and; expanding this polyester foam obtained in such a manner in the presence of an expanding agent whereby forming the polyester foam having a homogeneous structure thanks to the addition of a siliconized surfactant to the molten mass.
