Electrospun nanocomposite membranes incorporated with PVdF/PVP and carbon blacks for supercapacitor applications
Jabbarnia, Amir; Ghazinezami, Ali; Saeednia, Leyla (Wichita State University. Graduate School, 2014-04-25)Supercapacitors are new generation of energy storage devices using high surface area conductive or semiconductive materials. The supercapacitors show a better performance compared to the other chemical storage devices ... -
Fire retardancy of nanocomposites incorporated with graphene and nanoclay inclusions
Ghazinezami, Ali; Jabbarnia, Amir (Wichita State University. Graduate School, 2013-05-08)The applications of polymeric materials in many industries show the great importance of these materials. Due to their molecular structure and chemical composition, polymeric materials are highly flammable. This study is ... -
Fire retardancy of polymeric materials incorporated with nanoscale inclusions
Ghazinezami, Ali; Jabbarnia, Amir; Asmatulu, Ramazan (American Society of Mechanical Engineers, 2014)Polymeric materials have a wide variety of applications in many manufacturing industries. However, because of the molecular structures and chemical compositions of polymeric materials, they have considerably low resistances ... -
Investigating the thermal, mechanical, and electrochemical properties of PVdF/PVP nanofibrous membranes for supercapacitor applications
Jabbarnia, Amir; Khan, Waseem Sabir; Ghazinezami, Ali; Asmatulu, Ramazan (Wiley Periodicals, Inc., 2016-08-10)Polyvinylidene fluoride and polyvinylpyrrolidone polymers incorporated with carbon black nanoparticles (50nm) were electrospun to fabricate nanofibrous membranes for supercapacitor separators. Different weight percentages ... -
New progress in self-healing technology of composite wind turbine blades
Patlolla, Vamsidhar Reddy; Jabbarnia, Amir (Wichita State University. Graduate School., 2012-04-18)Wind turbine blades are subjected to cyclic loadings, resulting in the development of micro and nanocracks, which in course of time becomes macro cracks, thus leading to fatigue and failure. The concept of self-healing ... -
Recent progress on conventional and non-conventional electrospinning processes
Khan, Waseem Sabir; Asmatulu, Ramazan; Ceylan, Muhammet; Jabbarnia, Amir (Springer Netherlands, 2013-08)Electrospinning is a process of producing micro- and nanoscale fibers using electrostatically charged polymeric solutions under various conditions. Most synthetic and naturally occurring polymers can be electrospun using ... -
Synthesis and characterization of electrospun polyvinylidene fluoride (PVdF)-based polymeric separators for supercapacitor applications
Jabbarnia, Amir (Wichita State University, 2014-12)This study outlines the synthesis and characterization of electrospun polymer-based nanofibers with carbon black nanoinclusions for separators in supercapacitor applications. Supercapacitors, also known as ultracapacitors, ...
