Preparation and characterization of polyurethane/soluble eggshell membrane nanofibers.
Superfine Particles (SP) of soluble eggshell membrane and medical grade polyurethane (MPU) blend nanofibers were prepared by electrospinning different blend ratios of SP/MPU suspensions for regeneration of the natural fiber-like structure of the eggshell membrane. The addition of SP had no obvious effect on the electrospinning process of MPU nanofibers, and the SP were randomly dispersed in the...
متن کاملStress-Strain Behavior of Thermoplastic Polyurethane
The large strain nonlinear stress-strain behavior of thermoplastic polyurethanes (TPUs) exhibits strong hysteresis, rate dependence and softening. Thermoplastic polyurethanes are copolymers composed of hard and soft segments. The hard and soft segments phase separate to form a microstructure of hard and soft domains typically on a length scale of a few tens of nanometers. Studies have revealed ...
متن کاملHow an eggshell is made.
o a housewife an egg is an article of food, and its shell serves to protect it from physical damage and to prevent the entry of dirt and microorganisms. To the hen an egg is a potential chick, and the shell serves not only as a protective covering but also as a source of calcium for the embryo and as a membrane through which the embryo respires. The eggshell performs its various functions with ...
متن کاملTissue-Engineered Vascular Graft of Small Diameter Based on Electrospun Polylactide Microfibers
Tubular vascular grafts 1.1 mm in diameter based on poly(L-lactide) microfibers were obtained by electrospinning. X-ray diffraction and scanning electron microscopy data demonstrated that the samples treated at T = 70°C for 1 h in the fixed state on a cylindrical mandrel possessed dense fibrous structure; their degree of crystallinity was approximately 44%. Strength and deformation stability of...
متن کاملTissue engineering of small diameter vascular grafts.
Tissue engineering, using either polymer or biological based scaffolds, represents the newest approach to overcoming limitations of small diameter prosthetic vascular grafts. Their disadvantages include thromboembolism and thrombosis, anticoagulant related haemorrhage, compliance mismatch, neointimal hyperplasia, as well as aneurysm formation. This current review represents an overview about pr...
