Modified chitosan nano-substrates for mycobacterial capture
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Tuberculosis (TB) is one of the world’s deadliest diseases, with one third of the population being infected by it. The diagnosis of active tuberculosis entails finding and identifying Mycobacterium ...
The non-covalent compatibilization of carbon nanotubes for use in polymeric composite materials
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Since the discovery of carbon nanotubes (CNTs), a large interest has developed around the
incorporation of these into polymeric matrices in order to introduce the excellent mechanical,
thermal and ...
Free volume of electrospun organic-inorganic copolymers
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Two series of amphiphilic, organic-inorganic graft copolymers of poly(methyl
methacrylate) and poly(dimethylsiloxane) (PMMA-graft-PDMS), as well as
poly(acrylonitrile) and poly(dimethylsiloxane) ...
Studies on porphyrin-based nanorods for artificial light harvesting applications
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: The work presented in this thesis throws light on the supramolecular approach in exploration of
bi-porphyrin nanorods system wherein self-assembly plays an important role. Porphyrin based
nanorods were ...
Amphiphilic electrospun fibres of poly(methacrylic acid)-graft-poly(dimethylsiloxane) copolymers as a means to controlling electrospun fibre morphology and obtaining nanofibre hydrogels
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Novel poly(methacrylic acid)-graft-poly(dimethylsiloxane) copolymers were synthesised by
conventional free radical reactions using a poly(dimethylsiloxane) macromonomer. The
polymers were electrospun ...
Controlled release of an antimicrobial substance from polymeric matrices
(Stellenbosch : Stellenbosch University, 2016-03)
ENGLISH ABSTRACT : The main goal of this study was to develop polymeric artifacts (nanofibers and films) infused with an antimicrobial agent, 2,3-dihydroxybenzoic acid and study the release of DHBA as a function of the ...
Electrospun carbon nanotube filled composite nanofibers by non-covalent compatibilization
(Stellenbosch : Stellenbosch Univesity, 2016-03)
ENGLISH ABSTRACT: This study covers the successful production of poly(acrylonitrile) (PAN)/multi-walled-carbon-nanotube (MWCNT) fibrous composites by the incorporation of noncovalently functionalized MWCNTs in various ...
Electrospun composite nanofibres with magnetic carbon nanotubes
(Stellenbosch : Stellenbosch University, 2016-03)
ENGLISH ABSTRACT: Functional composite nanofibres incorporated with magnetic carbon nanotubes (CNTs) were successfully synthesized using the electrospinning technique. This is the first example of the preparation of such ...
Coaxial electrospinning for the reinforcement of nanofibre mats
(Stellenbosch : Stellenbosch University, 2017-03)
ENGLISH ABSTRACT: Styrene -N-(N’,N’-dimethyl-3-aminopropyl)maleimide copolymer (SMI-P) was prepared by treating styrene-maleic anhydride copolymer (SMA) with N,N-dimethyl-3-aminopropylamine (DMAPA). The SMI-P copolymer was ...
