Synthesis of permanent non-leaching antimicrobial polymer nanofibers
(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 ...
Polymer-clay nanocomposites prepared by RAFT-supported grafting
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: In materials chemistry, surface-initiated reversible deactivation radical polymerisation (SI-RDRP) has emerged as one of the most versatile routes to synthesising inorganic/organic hybrid materials ...
Surface modification of styrene maleic anhydride nanofibers for efficient capture of Mycobacterium tuberculosis
(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 ...
Novel multidimensional fractionation techniques for the compositional analysis of impact polypropylene copolymers
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Impact Polypropylene Copolymers (IPCs) are extremely complex materials, consisting of a mixture of
polypropylene homopolymer and copolymers having different comonomer (ethylene) contents and
chemical ...
The preparation of polyolefin nanofibres by solution electrospinning
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Solution electrospinning is a technique used to produce polymer micro- or nanofibres. Recently a great deal of research has been done on the application of polymer nanofibres produced by this method.
The ...
The effect of molecular composition on the properties of polyolefin-wood composites
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Polymer composites, and in particular wood-polymer composites have become commercially and
environmentally important materials. Studies in polyolefin-wood composites have mostly focused
on polypropylene ...
Alternating hetero-arm copolymer molecular brushes as scaffolds for inorganic nano-wires
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: This study describes the synthesis and self-assembly of hetero-arm molecular brushes (hetero-arm MBs). These MBs consist of two polymeric side chains (SCs) of different natures, alternatingly distributed ...
Nanocolorants for hot-melt inks
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: A new class of nanocolorants is described for the use as a colorant in hot-melt ink application for ink-jet printing technology. An inverse miniemulsion polymerization process was utilized successfully ...
The supramolecular chemistry of novel synthetic biomacromolecular assemblies
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: Over the past decade peptide bola-amphiphiles have been the subject of much attention
because of their role as potential models of functionalised membranes and as new
generation surfactants. In the quest ...
The development of analytical techniques for studying degradation in impact polypropylene copolymers
(Stellenbosch : University of Stellenbosch, 2009-03)
Unstabilised polyolefins are susceptible to degradation when exposed to molecular oxygen, heat, irradiation as well as chemical and mechanical stimuli. Oxidation leads to changes in molecular properties such as molecular ...
