First claim
Opening claim text (preview).
The invention claimed is: 1. A superabsorbent polymer composite comprising cellulosic nanofibrils having a diameter equal to or less than 100 nm incorporated within a three-dimensional network of polymer chains of a superabsorbent polymer. 2. The superabsorbent polymer composite according to claim 1 , wherein the composite does not contain cellulosic fibers having an average diameter greater than 100 μm. 3. The superabsorbent polymer compos…
