资源简介：
A process for dissolving oxidized cellulose and forming a plurality of oxidized cellulose particles. The process comprises: contacting an oxidized cellulose with a solvent under an inert atmosphere to form a swelled oxidized cellulose; adjusting the swelled oxidized cellulose to a first temperature; contacting the swelled oxidized cellulose with a salt under the inert atmosphere to form the oxidized cellulose solution; adjusting the oxidized cellulose solution to a second temperature that is lower than the first temperature; and contacting the oxidized cellulose solution with at least one non-solvent to form the plurality of oxidized cellulose particles.
