Small strain mechanical properties of latex-based acrylic nanocomposite films

John Christopher Plummer, Riccardo Ruggerone

A waterborne latex-based technique has been used to prepare acrylic films with laponite contents up to about 25 vol%. The laponite was attached to the surfaces of the latex particles, giving a cellular arrangement of laponite-rich regions at high laponite ...

Highly filled polymer nanocomposite films derived from novel nanostructured latexes

Riccardo Ruggerone

The overall aim of this thesis has been to assess the potential of latex-based technologies for the preparation of polymer/clay nanocomposites. The key feature of latex-based technologies is that they offer the possibility of improved control of the final ...

Fracture mechanisms in polystyrene/laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Transmission electron microscopy (TEM) has been used to investigate the effect of laponite clay on microdeformation in thin latex-based polystyrene (PS) films, in which the laponite was concentrated at the original interfaces between the PS particles. At r ...

Mechanical properties of highly filled latex-based polystyrene/laponite nanocomposites

John Christopher Plummer, Riccardo Ruggerone

Nanocomposite films containing up to 50 wt. % laponite have been prepared from emulsion polymerized polystyrene (PS)/laponite latexes with the laponite attached to the PS particle surfaces. Below Tg, the observed stiffness increases are accounted for by cl ...

Highly filled Polystyrene-laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Polystyrene-based nanocomposite films containing up to 20 wt% laponite clay have been prepared by emulsion polymerization. Significant increases in the storage and tensile moduli were observed in both the glassy and rubbery state on laponite addition. Howe ...
