Highly filled water based polymer/clay hybrid latexes
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: The use of co-sonication (ad-miniemulsion) polymerisation for the preparation of highly filled polymer/clay hybrid latexes is described. Laponite (Lap) content levels in the range of 10–50 wt% were ...
Preparation of polymer-clay nanocomposites via dispersion polymerization using tailor-made polymeric surface modifiers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Fully exfoliated polystyrene-clay nanocomposites were prepared via free radical polymerization in dispersion polymerization, in a mixture of ethanol and water. Sodium montomorillonite clay (MMT) was ...
Novel electrospun fibres of amphiphilic organic-inorganic graft copolymers of poly(acrylonitrile)-graftpoly( dimethylsiloxane) for silicone composite reinforcement
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Novel silicone nanocomposites were prepared using poly(acrylonitrile) (PAN) based reinforcing
fibres as well as multi-walled carbon nanotubes (MWCNTs). Compatibility of the fibre fillers with
the silicone ...
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 ...
