Embodiment 1
[0050] The embodiment of the present invention provides a method for preparing a novel self-assembled electrospun nanofiber membrane for water filtration, comprising the following steps:
[0051] S1. Preparation of Enteromorpha polysaccharides
[0052] Put the crude polysaccharide of Enteromorpha enteromorpha into a beaker, and add water into the beaker to dissolve it, then put the solution into the osmometer for osmosis treatment, then put the infiltrated solution into the purification equipment for purification treatment, and then put the solution into into the dryer to obtain pure Enteromorpha polysaccharide;
[0053] S2. Prepare the solution
[0054] Weigh a certain amount of Enteromorpha polysaccharide and dissolve it in 50% (V / V) acetic acid, and configure a solution of Enteromorpha polysaccharide with a concentration of 2% (W / V); weigh a certain amount of chitosan and dissolve it in 50% (V / V) / V) In acetic acid, configure a chitosan solution with a concentration of 2%...
Embodiment 2
[0067] The embodiment of the present invention provides a method for preparing a novel self-assembled electrospun nanofiber membrane for water filtration, comprising the following steps:
[0068] S1. Preparation of Enteromorpha polysaccharides
[0069] Put the crude polysaccharide of Enteromorpha enteromorpha into a beaker, and add water into the beaker to dissolve it, then put the solution into the osmometer for osmosis treatment, then put the infiltrated solution into the purification equipment for purification treatment, and then put the solution into into the dryer to obtain pure Enteromorpha polysaccharide;
[0070] S2. Prepare the solution
[0071] Weigh a certain amount of Enteromorpha polysaccharide and dissolve it in 50% (V / V) acetic acid, and configure a solution of Enteromorpha polysaccharide with a concentration of 2% (W / V); weigh a certain amount of chitosan and dissolve it in 50% (V / V) / V) In acetic acid, configure a chitosan solution with a concentration of 2%...
Embodiment 3
[0084] Such as Figure 1-11 As shown, the embodiment of the present invention provides a novel water filtration self-assembled electrospun nanofiber membrane, and a method for observing the surface morphology of the nanofiber membrane, comprising the following steps:
[0085] Cut the fiber membrane into square pieces with a size of 0.5cm*0.5cm, fix it on the stage with conductive glue, observe the surface morphology of the fiber and the morphology of the scaffold with a field emission scanning electron microscope, and analyze the results by SEM , 5 pictures were randomly selected for each sample, 100 fibers were randomly selected for each picture, and the diameter of nanofibers was counted using ImageJ software. Pure Enteromorpha polysaccharides will not form fibers when electrospun from acetic acid. High solubility in solvents, resulting in reduced viscosity, cannot achieve the high degree of entanglement required for efficient electrospinning; however by adding PVA to the CS...
