"Sodium alginate/Key technology of wet macro preparation of krill protein nerve catheter materials

Guo Jing, Dalian University of Technology

The project designed and developed the internal and external dual channel gradient wet molding based on sodium alginate and krill protein-In situ freezing and pore forming technology with salt solution solvent realized wet macro preparation of neural conduit materials. The prepared nerve conduit material has multiple cross-linking (calcium alginate ion cross-linking, protein calcium ion cross-linking and alginate/Protein cross-linking and multi-dimensional hydrogen bond) structure, as well as radial gradient pore structure, inner wall guide bulge structure and high porosity structure, ensure that neural conduit materials have good biocompatibility, biodegradability, help nerve cells to differentiate and grow, and provide a new material for the biomedical field. The proposed near viscosity strategy of skin layer solution, core layer solution and coagulating bath solution effectively solves the separation and deformation of skin layer and core layer. At the same time, the existence of core layer can form a support for the skin layer, effectively avoiding the collapse and deformation problems caused by volume shrinkage in the molding and freezing of tubular materials, and providing a new idea and method for the preparation of large-diameter porous materials.Application for Chinese invention patent1Pieces; publishSCIInclude papers5Article.

"Melt differential electrospinningTPUResearch on Preparation Technology of Waterproof and Moisture Permeable Membrane

Li Haoyi, Beijing University of Chemical Technology

The project has prepared waterproof, moisture permeable and breathable materials with high elasticity and good skin affinity; The preparation process of thermoplastic polyurethane waterproof and moisture permeable fiber membrane was explored to form a stable and efficient preparation of fiber average diameter3.93μm, average pore diameter of fiber membrane3.81μmPreparation technology of thermoplastic polyurethane fiber membrane; The moisture permeability of the fiber membrane showed a unidirectional trend with the spinning voltage, auxiliary air velocity and spinning time, and the hydrostatic pressure of the fiber membrane was mainly affected by the spinning time. Under the optimal process conditions, the maximum moisture permeability of the fiber membrane (before washing) is2970 g/(m2·24h), waterproof performance (before washing) is4.4 kPa。The project has applied for invention patent2Items, publishing articles1Article.
