Research Institute from South Africa

The Council for Scientific and Industrial Research, commonly known as the CSIR, is a world-class African research and development organisation established through an Act of Parliament in 1945. The CSIR undertakes directed, multidisciplinary research and technological innovation that contributes to the improved quality of life of South Africans. The CSIR’s shareholder is the South African Parliament, held in proxy by the Minister of Higher Education, Science and Innovation. CSIR vision We are accelerators of socio-economic prosperity in South Africa through leading innovation. CSIR mission Collaboratively innovating and localising technologies while providing knowledge solutions for the inclusive and sustainable advancement of industry and society. CSIR values CSIR values statement: Our beliefs, principles and the impact we wish to make to improve the quality of life of South Africans are EPIC. Team CSIR pursues Excellence, celebrates People, personifies Integrity, and welcomes Collaboration. Our mandate “The objects of the CSIR are, through directed and particularly multi-disciplinary research and technological innovation, to foster, in the national interest and in fields which in its opinion should receive preference, industrial and scientific development, either by itself or in co-operation with principals from the private or public sectors, and thereby to contribute to the improvement of the quality of life of the people of the Republic, and to perform any other functions that may be assigned to the CSIR by or under this Act.” (Scientific Research Council Act 46 of 1988, amended by Act 71 of 1990)

4. Flow Characteristics, Mechanical, Thermal, and Thermomechanical Properties, and 3D Printability of Biodegradable Polylactide Containing Boehmite at Different Loadings.

This work investigates the effects of modification of polylactide (PLA) using dicumyl peroxide (DCP) as a crosslinker and Joncryl as a chain extender on boehmite distribution. The PLA/boehmite (PLA/BA) composites at various concentrations were prepared via a twin-screw extruder. Transmission electron microscopy showed more agglomerations of BA particles when Joncryl and DCP were added individually to the PLA matrix, with lesser agglomeration upon...

20. Structural characterization of polymer nanocomposites

The performance of a heterogeneous material, such as polymer nanocomposites (PNCs) is dictated by three main factors: (i) the inherent properties of the components; (ii) interfacial interactions; and (iii) structure of the PNCs. The structure of a PNC depends on the dispersion and distribution of the nanoparticles (NPs) in the polymer matrix. However, improving the dispersion by mechanical means or via chemical bonding can influence the propertie...

A New Approach for the Quantitative Analysis of Degree of Dispersion of Clay Particles in the Polymer Matrix by Electron Microscopy Combined with Smallangle X-ray Scattering

The main objective of this work is to propose a new approach for the quantitative analysis of the degree of dispersion of clay particles in the polymer matrix by small-angle X-ray scattering (SAXS) combined with electron microscopy. The dispersed structure of the clay particles in the poly[(butylene succinate)-co-adipate] (PBSA) matrix was studied by SAXS. The morphology of the nanocomposites was extensively studied by scanning transmission elect...

41. Thermal and rheological properties of biodegradable poly [(butylenesuccinate)-co-adipate] nanocomposites.

The thermal and rheological properties of clay-containing poly[(butylene succinate)-co-adipate] (PBSA) nanocomposites are reported. The nanocomposites of PBSA with various weight percentages of organically modified montmorillonite (OMMT) loadings have been prepared by melt-mixing in a batch-mixer. The melting and crystallization behaviours of PBSA and its nanocomposites have been studied using differential scanning calorimeter (DSC). The melt-sta...

Study on Nanoclay Dispersion in a Polymer Matrix by High-Resolution Electron Microscopy Combined with Electron Tomography

In this study, we choose poly[(butylene succinate)-co-adipate] (PBSA) as our model polymer. PBSA is a random copolymer of poly(butylene succinate) (PBS); which shows a variety of interesting physical properties, including biodegradability. The nanocomposite of PBSA with methyl tallow bis(2-hydroxylethyl) quaternary ammonium modified montmorillonite (MMT) (commercially known as C30B) were prepared by melt-mixing in a batch mixer. The nature of the...

39. Structural Analysis of Liquid Crystal Polymer Based Nanocomposites by X‐Ray Scattering.

The main theme of this work is to support the unusual melt-state rheological properties of the clay-containing nanocomposites of thermotropic liquid crystal polymers by small- and wideangle X-ray scattering. The changes of dispersion of silicate particles in the LCP matrix as well as change in crystal growth of LCP were extensively studied by X-ray scattering in both smalland wide-angle regions. The generalised indirect Fourier transformation ...

43. The quantitative analysis of nano-clay dispersion in polymernanocomposites by small angle X-ray scattering combined with electronmicroscopy

The main objective of this work is to propose a new approach for the quantitative analysis of the degree of dispersion of clay particles in the polymer matrix by small angle X-ray scattering (SAXS) combined with electron microscopy. Due to the low temperature processibility and good thermal stability, poly[(butylene succinate)-co-adipate] (PBSA) was chosen as a model polymer matrix for this study. The nanocomposites of PBSA with four different we...

44. Viscoelastic Properties of Clay‐Containing Nanocomposites ofThermotropic Liquid‐Crystal Polymer.

The nanocomposites of liquid-crystal polymer (LCP) with two different weight per cents of claywere preparedviathe melt extrusion method. To investigate the properties of the materials inthe linear and non-linear viscoelastic regions, both oscillatory and rotational tests were carriedout. The results showed that the nanocompositewith higher clay content exhibited an almostdefectless partially cross-linked structure com-pared to the nanocomposite w...

45. Influence of degree of intercalation on the crystal growth kinetics of poly [(butylene succinate)-co-adipate] nanocomposites

The influence of the degree of intercalation of polymer chains in the two dimensional silicate galleries on the crystallization behavior of poly[(butylene succinate)-co-adipate] (PBSA) is being reported on. The nanocomposites were prepared by melt-blending of PBSA and organically modified montmorillonite (OMMT) in a batch-mixer. Two different types of commercially available OMMTs, with different extents of miscibility of organic modifiers with PB...
