Electrospinning technology

Abstract

Electrospinning represents a technology for producing polymer nanofibers which is becoming popular in 21st century. It has not yet been investigated completely and its research is a great challenge for scientisis around the world. Electrospinning is a widely used technology for electrostatic formation of fibers with the usage of electrical forces. The produced polymer fibers are in diameter between 2 nm and several micrometers, and they are obtained from polymer solutions or melts of natural and synthetic polymers. The history of electrospinning and the description of the set-up parts for electrospinning are included in this work. The impact of the process parameters and solution parameters on the fiber morphology and the results of the performed experiments with the PVB-SiO2 composite fibers are presented here. In the end, the summary of the applications of electrospun fibers is given.

Elektrospining predstavlja tehnologiju dobijanja nanovlakana koja sve više postaje aktuelna u 21. veku. Još uvek nije u potpunosti ispitana i njeno istraživanje predstavlja veliki izazov za naučnike širom sveta. Elektrospining je veoma rasprostranjena tehnologija za elektrostatičko formiranje vlakana pri upotrebi električnih sila. Proizvode se polimerna vlakna sa prečnicima u intervalu od 2 nm do nekoliko mikrometara korišćenjem polimernih rastvora ili rastopa prirodnih i sintetičkih polimera. Ovaj rad obuhvata istorijat elektrospininga i opis delova aparature za elektrospining. Potom su navedeni uticaji procesnih parametara i parametara rastvora na morfologiju proizvedenih vlakana posle kojih su predstavljeni rezultati izvedenog eksperimenta sa PVB-SiO2 kompozitnim vlaknima. Na kraju je dat pregled primena elektrospinovanih vlakana.
