Investigation of the Properties of Polyurethane Elastomer Based on Synthesis and Characterization of PTHF-GAP-PTHF Triblock Copolymer
Binder has a key role in the performance of composite propellants. The binders are classified into two neutral and high-energy categories. GAP is one of the most important energetic binders, but it has poor mechanical and thermal properties. The goal of this investigation is to improve the properties of GAP by copolymerizing it with polytetrahydrofuran. New energy triblock copolymer was synthes...
متن کاملSynthesis of Polyurethane/Hyaluronic acid/Royal Jelly Electrospun Scaffold and Evaluating its Properties for Wound Healing
Background and purpose: Studies showed that biocompatible and biodegradable materials in tissue engineering can be used to heal wounds. The aim of this study was to fabricate polyurethane/royal jelly/hyaluronic acid scaffold with suitable biological properties for wound healing using electrospinning method. Materials and methods: In this applied experimental study, to make a nanofiber scaffold...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولThe Fracture Energy and Some Mechanical Properties of a Polyurethane Elastomer
The energy required to form a unit of new surface in the fracture of a polyurethane elastomer is determined. The rate sensitivity of the material has been reduced by swelling it in toluene. This paper primarily describes the experimetal work of measuring the lower limit of the fracture energy. With this value and the creep compliance as a basis, the rate dependence of fracture energy for the un...
متن کاملFacile preparation of antibacterial, highly elastic silvered polyurethane nanofiber fabrics using silver carbamate and their dermal wound healing properties.
In this study, polycarbonate diol/isosorbide-based antibacterial polyurethane nanofiber fabrics containing Ag nanoparticles were prepared by electrospinning process. Bio-based highly elastic polyurethane was prepared from hexamethylene diisocyanate and isosorbide/polycarbonate diol (8/2) by a simple one-shot bulk polymerization. Ag nanoparticles were formed using simple thermal reduction of sil...
