Title (EN) POLYSACCHARIDE PHYLLOSILICATE ABSORBENT OR SUPERABSORBENT NANOCOMPOSITE MATERIALS
(FR) MATERIAUX NANOCOMPOSITES ABSORBANTS OU SUPERABSORBANTS A BASE DE POLYSACCHARIDE ET DE PHYLLOSILICATE
Abstract: front page image
(EN)The present invention relates to an absorbent or a superabsorbent nanocomposite material comprising a polysaccharide and a phyllosilicate. The polysaccharide component is a biodegradable polysaccharide that is either a self-entangled glass-like polysaccharide or a crosslinked polysaccharide. The phyllosilicate component is either an exfoliated or a semi-exfoliated clay.
(FR)La présente invention concerne un matériau nanocomposite absorbant ou superabsorbant comprenant un polysaccharide et un phyllosilicate. Le constituant polysaccharide est un polysaccharide biodégradable qui est soit un polysaccharide vitreux auto-enchevêtré, soit un polysaccharide réticulé. Le constituant phyllosilicate est soit un argile expansé, soit un argile semi-expansé.
