摘要

The present invention relates to a polyvinyl alcohol/sodium alginate/hydroxyapatite composite fibrous membrane, and a preparation method and an application thereof. The preparation method of the composite fibrous membrane includes the following steps: firstly, reacting a diammonium hydrogen phosphate with a calcium nitrate to prepare a hydroxyapatite, and performing ultrasonic dispersion on the hydroxyapatite with a sodium alginate to form a stable hydroxyapatite suspension; separately preparing a sodium alginate solution of which the mass fraction is 2% and a polyvinyl alcohol solution of which the mass fraction is 18% using the above stable hydroxyapatite suspension; and finally, proportionally and uniformly mixing the two solutions, and performing electrospinning.
