Fabrication And Characterization Of Polycarbonate Polyurethane (Pcpu) Nanofibers Impregnated With Nanofillers, Hruday Chand Katakam
USF Tampa Graduate Theses and Dissertations
Polycarbonate polyurethane (PCPU) has been studied as a novel polymer impregnated with nanoparticles for improved mechanical, thermal and adhesion properties [4]. This study investigates the synthesis of polycarbonate polyurethane (PCPU) polymeric nanofiber membranes by the process of electrospinning. This study further examines all the parameters associated with electrospinning a novel PCPU polymeric solution impregnated with nanofillers, such as nanoparticles, to produce fiber membranes. Tetrahydrofuran (THF) and N, N dimethylformamide (DMF) are used as solvents to dissolve PCPU polymer. One percent (1%) of nanofillers like silver and silica nanoparticles are added to PCPU polymer solution to investigate the impact on polymer …
Investigation Of Opuntia Ficus-Indica Mucilage Nanofiber Membrane Filtration For Water Systems, Rasudha Muppaneni
Investigation Of Opuntia Ficus-Indica Mucilage Nanofiber Membrane Filtration For Water Systems, Rasudha Muppaneni
USF Tampa Graduate Theses and Dissertations
This work investigates the fabrication, characterization and testing of Opuntia ficus-indica mucilage nanofibers to be utilized in water filtration systems. These mucilage nanofibers are formed using different polymers through a process called electrospinning. The polymers used to promote the formation of nanofibers are poly vinyl alcohol (PVA) and polystyrene (PS). The mucilage is a jelly like substance extracted from the pads of the cactus plant. It is a mixture of proteins, complex polysaccharides and monosaccharaides. It is an inexpensive, non-toxic, biodegradable and biocompatible material which is present in abundance. The mucilage extracted from the pads is mixed with acetic acid …
