Uticaj rastvarača na stabilnost procesa elektropredenja polimernih nanovlakana
Univerzitet u Beogradu, Tehnološko-metalurški fakultet

Projekat

Razvoj opreme i procesa dobijanja polimernih kompozitnih materijala sa unapred definisanim funkcionalnim svojstvima (MPNTR - 34011)
Sinteza, razvoj tehnologija dobijanja i primena nanostrukturnih multifunkcionalnih materijala definisanih svojstava (MPNTR - 45019)

Sažetak

U okviru ovog rada ispitivana je mogućnost dobijanja poli-(metilmetakrilat)nih (PMMA) vlakana metodom elektropredenja (electrosinning.) Primenom različitih procesnih parametara (rastvarača, koncentracije rastvora, protoka rastvora i rastojanja izmenu vrha igle i kolektora bilo je moguće ispitati uticaj ovih parametara na ravnomernost prečnika i kvalitet dobijenih vlakana. Karakterizacija dobijenih vlakana izvedena je primenom FTIR metode, DSC metode, skenirajuće elektronske mikroskopije (SEM) i metodom analize slike Image-pro. Na ovaj našin odreneni su najoptimalniji procesni parametri za dobijanje nanovlakana ravnomernog prečnika i bez poroznosti.

Ključne reči
