Аннотация: A procedure has been developed to fabricate polymer tubes using solution casting inside template tubes. Polyester solution placed inside the vertically fixed template evaporated forming a hollow tube on the inner walls of the template. Silicone tubes used as the templates were permeable to solvent vapors and had relatively low adheПоказать полностьюsion to materials of the fabricated tubes, enabling their effortless removal. Parameters of the polymer tubes were determined by a type of the polymer, its concentration in the solution, and the inner diameter of the template. In the first method, a clamp was placed on the lower end of the template tube. A thickness of the new tube walls gradually increased from the open to the clamped end of the template tube. In another method viscous polymer solution without clamping was used; in this case, a polymeric bulkhead was formed in the middle of the tube. Two microbial polyesters, poly-3-hydroxybutyrate and poly-3-hydroxybutyrate-co-3-hydroxyvalerate, and also synthetic poly-L-lactide were used as model polymers. © 2020 Elsevier B.V.
