Abstrakty

Biodegradable polymers like PLA and PCL have wide application in tissue engineering because of their biocompatibility, degradation and mechanical properties. In this study, the optimised electrospinning parameters of PLA/PCL composite membranes were determined with scanning electron microscopy to obtain smooth and relatively fine microfibre. The properties and structure of electrospinning PLA, PCL and PLA/PCL(70/30) membranes were investigated by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), the water contact angle, water absorption degree and tensile strength. The results revealed that PLA/PCL composite membranes possessed better mechanical and hydrophilic properties when compared to single component microfibre membranes like PLA and PCL. The improvements above are conducive to microfibre membrane application in the biomedical sector.

Biodegradowalne polimery, takie jak PLA i PCL znajdują wiele zastosowań w inżynierii tkankowej ze względu na swoją biokompatybilność, oraz właściwości mechaniczne. W badaniach, wyznaczono optymalne parametry elektroprzędzenia błon kompozytowych PLA/PCL stosując metodę skaningowej mikroskopii elektronowej, w celu otrzymania gładkich i cienkich mikrowłókien. Właściwości i strukturę elektroprzędzionych błon PLA, PCL i PLA/PCL(70/30) badano za pomocą elektroskopii skaningowego (SEM), różnicowej kalorymetrii skaningowej (DSC), dyfrakcji rentgenowskiej (XRD), metody kąta zwilżania wody, współczynnika absorpcji wody i wytrzymałości na rozciąganie. Wyniki wykazały, że błony kompozytowe PLA/PCL posiadają lepsze właściwości mechaniczne i hydrofilowe, w porównaniu do jednoskładnikowych błon z mikrowłókien, takich jak PLA i PCL. Powyższe ulepszenia sprzyjają zastosowaniu membran z mikrowłókien w branży biomedycznej.
