The porous cellulose materials are fabricated from cellulose acetate (CA) and Na salts. When composite films consisting of CA and NaNO3 are exposed to water-pressure, the maximum flux reached to 8.6 L m~(-2)h~(-1). The generated water flux is attributable to the partial plasticization in polymer chains by hydrated NaNO3. The flexible polymer chains by hydrated salts can be the pores by external physical forces. Surprisingly, the CA/NaNO3 film shows a high porosity of 78.15 % and pore shapes was confirmed via scanning electron microscopy. Moreover, it preserves the excellent heat resistance properties, confirmed by thermal gravimetric analysis.
