Compounding and rheometry of PLA nanocomposites with coated and uncoated hydroxyapatite nanoplatelets (2016)
Conference Proceeding
Tomczynska, M. M., Choong, G. Y., De Focatiis, D. S., Grant, D. M., & Parsons, A. J. (in press). Compounding and rheometry of PLA nanocomposites with coated and uncoated hydroxyapatite nanoplatelets

Polylactic acid and novel nanoplatelets of hydroxyapatite (HANP) were compounded in a laboratory scale twin-screw extruder and injection moulded to shape. The effect of HANP loading content, between 1 wt% and 10 wt%, and of HANP surface coating with... Read More

Viscoelastic melt rheology and time-temperature superposition of polycarbonate – multi-walled carbon nanotube nanocomposites (2013)
Journal Article
Choong, G. Y., De Focatiis, D. S., & Hassell, D. G. (in press). Viscoelastic melt rheology and time-temperature superposition of polycarbonate – multi-walled carbon nanotube nanocomposites. Rheologica Acta, 52(8), doi:10.1007/s00397-013-0706-6. ISSN 0035-4511

This work investigates the linear and non-linear viscoelastic melt rheology of four grades of polycarbonate melt-compounded with 3 wt% Nanocyl NC7000 multi-walled carbon nanotubes and of the matching matrix polymers. Amplitude sweeps reveal an earlie... Read More

Melt-processed PLA/HA platelet nanoparticle composites produced using tailored dispersants
Conference Proceeding
Parsons, A. J., Walton, K., Hild, F., Ilchev, A., Gimeno-Fabra, M., Tomczynska, M. M., …Irvine, D. J. (in press). Melt-processed PLA/HA platelet nanoparticle composites produced using tailored dispersants

Hydroxyapatite (HA) nanoparticles, similar to those seen in the structure of human bone, have been produced via hydrothermal synthesisand used to produce nanocomposite materials via melt blending with poly(lactic acid)(PLA). Both of these processes a... Read More
