Problems solved by technology

However, most of the existing technologies use regenerated cellulose and other materials to blend and freeze-dry to prepare composite films. The uniformity and stability of the composite films prepared by this method are poor, and the tissue repair ability and drug adhesion need to be further improved.

Embodiment 1

[0023] A preparation method of bamboo nanofiber composite regenerated cellulose tissue repair material, comprising the following steps:

[0024] Step 1: Weigh 20g of bamboo fiber, put it into 400g of NaOH solution with a mass fraction of 17.5%, and place it in a constant temperature water bath with a temperature of 100°C, boil for 60min, and then repeatedly wash the bamboo fiber with deionized water After reaching neutrality, place it in an oven at 70°C for 6 hours, and after drying, crush it into a coarse powder and pass it through an 80-mesh sieve;

[0025] Step 2: Put 16g LiCl into a container containing 40°C and 184g dimethylacetamide, fully dissolve LiCl under the action of a constant temperature magnetic stirrer, and prepare a solvent with a mass fraction of 8%. Take 100g of the solvent and step 10g of the prepared bamboo powder was mixed and stirred in a 60°C constant temperature water bath for 3 hours, placed in an ultrasonic cell pulverizer, and ultrasonically treated...

Abstract

The invention discloses a method for preparing a bamboo nanofiber composite regenerated cellulose tissue repairing material and belongs to the technical field of tissue repairing material preparation. The method comprises the following steps: preparing a bamboo nanofiber solution, preparing a regenerated cellulose spinning solution, and performing electrostatic spinning, thereby obtaining the repairing material. The tissue repairing material prepared by using the method has good antibacterial properties, mechanical properties, tissue repairing properties and medicinal adhesion properties.

Description

technical field [0001] The invention belongs to the technical field of preparation of tissue repair materials, and in particular relates to a preparation method of bamboo nanofiber composite regenerated cellulose tissue repair materials. Background technique [0002] As a natural biopolymer, cellulose has biodegradability, biocompatibility and unique physical, chemical and mechanical properties, and has become a research hotspot in the field of new biomedical materials. However, most of the existing technologies use regenerated cellulose and other materials to blend and freeze-dry to prepare composite films. The uniformity and stability of the composite films prepared by this method are poor, and the tissue repair ability and drug adhesion need to be further improved. . Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a preparation method of a bamboo nanofiber composite regenerated cellulose tissue repair material ...
