Electrospinning of polyacrylonitrile nanofibres with additives : study of orientation and crystallinity

Greyling, Corinne Jean (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: Polyacrylonitrile, (PAN), polymers are of interest due to their many unique characteristics in comparison to most other fibre forming polymers. The focus of this study was the effect of electrospinning ...
Single bubble-electrospinning of polyvinyl alcohol and polyacrylonitrile

Pringle, Carla (Stellenbosch : Stellenbosch University, 2011-12)

ENGLISH ABSTRACT: Needle-electrospinning is an uncomplicated and highly versatile nanofiber (fiber diameter of 50 to 500 nm) production technique. Nevertheless the process can only produce 0.01 to 1.0 g/h/m2 of nanofibers, ...
Studies towards high-throughput production of nanofiber yarns

Smit, Eugene A. (Stellenbosch : Stellenbosch University, 2008-12)

ENGLISH ABSTRACT: Electrospinning is a simple yet versatile method used for producing nanofibers from various materials, including natural and synthetic polymers, polymer blends, ceramics and metals. The high specific ...
Surface modification of styrene maleic anhydride nanofibers for efficient capture of Mycobacterium tuberculosis

Cronje, Lizl (Stellenbosch : Stellenbosch University, 2012-12)

ENGLISH ABSTRACT: Tuberculosis (TB) is a major cause of morbidity and mortality across the world, affecting adults and children. Children infected with TB differ from adults, as their immunological and patho-physiological ...
Synthesis and characterization of electrospun organic-inorganic hybrid graft copolymer nanofibers of poly(methyl methacrylate) and polydimethylsiloxane

Swart, Morne (Stellenbosch : University of Stellenbosch, 2007-12)

Two series of poly(methyl methacrylate)-graft-poly(dimethylsiloxane) copolymers were synthesized via conventional free radical copolymerization of methylmethacrylate and monomethacryloxypropyl terminated PDMS macromonomers ...
Synthesis of permanent non-leaching antimicrobial polymer nanofibers

Bshena, Osama E. S. (Stellenbosch : Stellenbosch University, 2012-03)

ENGLISH ABSTRACT: Antimicrobial fibers are very useful in various fields such as air and water purification, wound dressings and protective bandages, where sterile environments are essential. The nonwoven nanofiber mats ...
