Construction and performance evaluation of electrostatic flocking procoagulant fabric
The electrical conductivity of traditional medical fibers was enhanced through in-situ polymerization of dopamine,resulting in the fabrication of a PET@PDA flocking fabric using electrostatic flocking technology.The response surface methodology was employed to optimize the parameters of the flocking process,and regression models were established to analyze the relationship between flocking process parameters and flocking density,specific surface area.An evaluation was conducted on the appearance,mechanical properties,cell compatibility,and blood compatibility of PET@PDA flocked fabric.The results demonstrate that PET@PDA10-2 flocking fabric exhibits high vertical orientation,significant porosity,excellent compression recovery performance(98.10％recovery rate under 50％strain),as well as favorable cytocompatibility and blood compatibility with remarkable coagulant promoting ability.Therefore,the electrostatically flocked PET@PDA fabric holds promising potential for applications in anticoagulant materials.
