Epoxidized natural rubber (ENR) has good properties with low glass transition temperature,
Tg, soft elastomer characteristics at room temperature and good elasticity. Blending ENR with
another polymer, such as poly(vinyl chloride) (PVC) which is an important commercial polymer,
for improve some properties of blends as well as good thermal stability is currently one of important
topics. PVC is hard, stiff material, although, mechanical properties, notably the flexibility, can be
extensively modified with plasticization. [1] A number of publications [1-4] deal with incorporation
of ENR with PVC. It also gives excellent contact between an electrolytic layer and an electrode in
batteries [5]. For fuel cell such as proton exchange membrane fuel cell have advantage as a viable
option due to their high energy efficiency and environmental friendly [2]. Polymer electrolyte
membrane is interesting of researchers because it is a new source of electrical power generation
and energy storage systems, such as displays, sensors, electric windows, super capacitors and
rechargeable batteries. Unlike conventional fiber spinning techniques (wet spinning, dry spinning,
melt spinning, gel spinning), which are capable of producing polymer fibers with diameters down to
the micrometer range, electrostatic spinning, or electrospinning is a process capable of producing
polymer fibers in the nanometer diameter range. [3] Electrospinning is the process in which a
polymer solution is ejection from a syringe that has a directly attached to a high power supply. This
power source generates a high voltage difference, usually selected between 5–30 kV, which support
the ejection of a liquid jet followed by solvent evaporation and the formation of a dry polymer fiber,
which deposits on a grounded cathode-connected metallic collector. Under the appropriate
conditions, a single jet may undergo solution instability and splay or split, resulting in smaller
diameter fibers. Therefore, by controlling the electrospinning parameters, optimal nanofibers can be
prepared.
