Title: Electrically‐assisted subsonic and supersonic solution blowing of monolithic and core-shell petroleum‐derived and bio-polymer nanofibers: Experiments and modeling

 

Abstract: The recently developed method of the electrically-assisted solution blowing holds great promise of high production rate of monolithic and core-shell nanofibers from different polymers including those which cannot be electrospun. Moreover, this method allows formation on demand of nanofibers in the range 20-50 nm which cannot be normally reached in electrospinning. The present talk discusses the following aspects of the electrically-assisted solution blowing: (i) Formation of monolithic and core-shell nanofibers from petroleum-derived polymers using subsonic blowing. (ii) Formation of monolithic and core-shell nanofibers from different biodegradable biopolymers and material characterization of their mats. (iii) The electrically-assisted solution blowing from multiple nozzles. (iv) Supersonic blowing of the 20-50 nm nanofibers and discovery of a novel χ-phase of nylon 6 characterized by the decrease of CH2 stretching, a shift of –NH stretching, a different type of hydrogen bonds and a ten-fold increase in Young’s modulus compared to the that of the post-processed macroscopic nylon 6 fibers. (v) Modeling of solution blowing.

Title: Functional polymer nanofibers: Opportunities and challenges

 

Abstract: System level multifunctionality is one of the most desired capability for device interfacing. Health monitoring and interactive multimedia technologies simplifying complex daily tasks are examples of the enormous possibilities offered by next generation multifunctional materials and devices. In this respect, 1D nanostructuring of organic materials is gaining continuous research interest, and polymer nanofibers, as building blocks of complex architectures, can lead to advances in many fields including photonics and electronics. In particular, properly designed functional nanofibers capable of sensing, storing and converting energy have been demonstrated. Mechanical flexibility, ease of processing, good chemical resistance and large sensitive areas are some of the properties associated to such novel materials. This in turn enables the exploitation of deformations induced by small forces through pressure, mechanical vibration, elongation/compression, as natural sources of power. Other interesting perspectives for devices in nanophotonics have been opened by the enhanced optical properties of electrospun nanofibers, including, among others, enhanced emission efficiency and waveguiding capability. In this scenario, leading electrospinning towards industrial applications will provide more and more opportunities for developments well beyond existing, consolidated technologies.

Title: Advances in functional metal oxide nanofibers

 

Abstract: Electrospinning has been recognized as one of the most efficient techniques for producing non-woven fiber webs on the order of several hundreds of nanometers by electrically charging a suspended droplet of polymer solution with/without inorganic precursors. Various types of materials with a high degree of porosity, a large surface area, and modified surface functionalities, have been electrospun into nanofiber structures. Thus far, electrospun nanofibers have served as highly optimized and versatile material platforms for a broad range of applications, such as for the filtration of liquids/gases, chemical sensors, nanofiber reinforced composites, active electrode materials for electrochemical cells, photo-electrodes, and in the biomedical field related to enzyme immobilization, wound dressing, and tissue engineering based drug release. More recently, significant efforts have been focused on practical applications of functional metal-oxide nanofibers. In this talk, I will introduce a collection of advances focused on the synthesis, characterization, and utilization of electrospun functional metal-oxide nanofibers, which are optimized for applications in exhaled breath sensors, novel catalysts for photoelectrochemical cells and Li-Air batteries, high capacity anode materials for Li-ion batteries.

 

Biography: Kim received his PhD degree (2002) from KAIST. From 2003 to 2005, he was a postdoctoral fellow with Prof. Harry L. Tuller at MIT. He returned to Korea Institute of Science and Technology as a senior research scientist. In Feb. 2011, he joined at KAIST as a faculty member in Department of Materials Science and Engineering. Dr. Kim’s current research emphasizes controlled processing and characterization of functional nanofibers via electrospinning for practical applications in exhaled breath sensors and energy storage devices such as Li-ion, Li-S, and Li-Air batteries. Dr. Kim had served as a conference chair in International Conference on Electrospinning 2012, which was held in Jeju, South Korea, 2012. He has published over 113 articles and holds 122 patents. Dr. Kim is a Deputy Editor of the Journal of Electroceramics (Springer).
