In order to elevate the value of regenerable resource of cellulose,regenerated cellulose film was soaked in an acrylamide aqueous solution,and then ceric ion was added to initiate the in-situ grafting polymerization of acrylamide under mild conditions through heterogeneous reaction.The composition and microstructure of films were studied and compared using Fourier transform infrared(FT-IR)spectroscopy and scanning electron microscopy(SEM).The composite film shows higher mechanical properties and water absorption abilities than the pure regenerated cellulose film,which reaches up to 107 MPa of tensile strength and 347% of saturated water absorption,respectively.Moreover,the composite film retains porous microstructure,and it exhibits higher water flux(26.4 L/(m2·h·MPa)),which is more than twice that of the regenerated cellulose film,and higher bovine serum albumin rejection rate than the regenerated cellulose film.Therefore,such a recyclable film would have great potential in water absorbing and water retaining materials and membrane separation fields.
