Article
The properties of the epoxy resin can be adjusted over a wide range based on the ingredient selection. In this work, kinetics of thermal degradation, adhesion, and dynamic-mechanical properties of polyetheramine (PEA)-modified epoxy networks have been discussed. Two types of PEAs, namely poly(ethylene glycol) amine (PEG-AM) and poly(propylene glyco...

Bone as a minerals' reservoir and rigid tissue of the body generating red and white blood cells supports various organs. Although the self-regeneration property of bone, it cannot regenerate spontaneously in severe damages and still remains as a challenging issue. Tissue engineering offers several techniques for regenerating damaged bones, where va...

The nanofiber mats of polyvinylidene fluoride (PVDF) containing various content of Graphene oxide (GO)-supported Titanium dioxide (TiO2)–Iron oxide (Fe3O4) hybrid nanoparticle-nanosheets were produced by solution electrospinning process. The TiO2–Fe3O4–GO nanoparticle-nanosheets with synergistic dielectric-magnetic-conductive properties were chemic...

Zeolite, as an intricate microporous material with redox sites, has been widely examined in many chemical industries. However, zeolite is not available everywhere, and it is expensive considering the price of raw materials from which it can be synthesized. In this study, ZSM-5 zeolite, as a local silica source with the high crystallinity, was synth...
Article
Flexibility, protection against harmful electromagnetic (EM) waves, and mimicking movement patterns of human beings are among the most required features of advanced textiles. In this regard, the present study was conducted to investigate the possibility of producing flexible, piezoelectric, and EM‐sensitive multifunctional nanofibers. Porous core‐s...
Chapter
In this research polyetheramine (PEA)-modified epoxy was prepared and the toughening mechanism of the modified networks was studied. According to the mechanical test results, incorporation of PEA into epoxy networks can significantly toughen the epoxy matrix. The addition of 15 phr PEA increased the critical stress intensity factor (KIC) and critic...

The lack of adequate blood/lymphatic vessels as well as low-potential articular cartilage regeneration underlines the necessity to search for alternative biomaterials. Owing to their unique features, such as reversible thermogelling behavior and tissue-like mechanical behavior, agarose-based biomaterials have played a key role in cartilage tissue r...
Article
Poloxamers, also called Pluronic, belong to a unique class of synthetic tri-block copolymers containing central hydrophobic chains of poly(propylene oxide) sandwiched between two hydrophilic chains of poly(ethylene oxide). Some chemical characteristics of poloxamers such as temperature-dependent self-assembly and thermo-reversible behavior along wi...
Article
Piezoelectric properties and adequate porosity play important roles in bone tissue engineering. In this paper we describe the fabrication of piezoelectric polypropylene (PP) foam using injection molding to be utilized as a potential cost-effective scaffold for bone tissue engineering. One-side mechanical skin removal from the foam was used to inves...
Article
The pollution arising from oil spills is a matter of great concern due to its damaging impacts on the ecological environment. In this work, polystyrene (PS)/Cloisite 20A nanocomposite fibers were fabricated by electrospinning method for the separation of oils and organic contaminate from water. The addition of Cloisite 20A nanoparticles could great...
Article
Mimicking the native tissue is an ultimate goal in tissue engineering. In this study, conductive chitosan was synthesized by coupling with aniline oligomers, and then conductive nanofibers were fabricated using electrospinning technique to mimic the tissue structure and properties. The conductivity of the resulting biomaterial was adjusted to ca. 1...

In this study, grafted gelatin with oligoaniline (GelOA) was synthesized and then mixed with Poly (vinyl alcohol) (PVA). Several scaffolds with different ratio of PVA/GelOA were electrospun to fabricate electroactive scaffolds. GelOA was characterized using Fourier‐transform infrared spectroscopy (FTIR); moreover, nanofiber properties were evaluate...

Article
A practical method to measure the energy dissipation in rubber vulcanizates under rolling condition has been considered. For this purpose, a modified rolling pendulum device was designed and constructed to eliminate the shortcomings of an initial design by Gent. This modified device has a working table, heated rolling plate, symmetric pendulum and...

Bladders are important rubber parts used for shaping and curing of tires. These parts are exposed to high temperature, high pressure, medium-large extension, and oxidative aging during their service life. Curing bladders are usually made of butyl-based rubber compounds vulcanized with phenolic resin vulcanization systems. To study the effect of Mon...
