 Investigation and modeling of pneumatic polymer solution jet formation in concentric nozzles system

Preparation of structures suitable as tissue engineering scaffolds requires not only a knowlege about requirements for biomaterials, but also a knowledge about production processes of those materials. One of the production processes of biomaterials we investigate in the Laboratory is Solution Blow Spinning (SBS). The proper conditions for stable polymer jet formation in this process were found due to realisation of the project: " Investigation and modeling of pneumatic polymer solution jet formation in concentric nozzles system", financed by National Science Centre, Poland, project reg. no 2014/13/N/ST8/01690.

 Below we present one part of the project results of investigation and modeling of polymer solution jet formation, but also modeling of the air flow through the concentric nozzles system we use in the Laboratory, and one part of rheological investigation of the applied polymer solution. In this project we investigated the stability of blow spinning process of poly-L-lactic (PLLA) solution with concentration of 5%w/w.

Presented results are only one part of the investigation leading us to discovery of the most suitable conditions to conduct solution blow spinning process in stable way. The way allowing the production of nanofibers without defects, with narrow and uniform size distribution. Nanofibrous product with those properties may find an application not only in tissue engineering, but also in filtration, manufacturing of protective clothes, and catalysts for chemical reactions (to mention only a few).
