Abs/iron nanocomposites prepared by cryomilling

Abstract

Acrylonitrile-Butadiene-Styrene (ABS)/iron nanocomposites have been prepared by cryomilling (highenergy ball milling under cryogenic temperature), and a microstructure of iron network in ABS matrix was obtained. The blending scale and homogenization of ABS/iron nanocomposites are observed by Atomic Force Microscope (AFM). The morphology and structure of cryomilled composite powders are characterized by means of Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), and X-ray Diffraction (XRD). The results indicate that upon cryomilling for 20 h, ABS and Fe are intimately blended with the single composite particle size less than 100 nm, the Fe phase domains less than 50 nm, and Fe grain size reduced to 20 nm. Both the fast rate of homogenization and size reduction are mainly attributed to the introduction of cryogenic temperature and comilling. The evidences suggest that cryomilling is a capable and promising technique for the production of polymer/metal nanocomposites.

Ball milling preparation and characterization of poly (ether ether ketone)/surface modified silica nanocomposite

“…Therefore, in this stage, both PEEK and SiO 2 particles got flattened and deagglomerated, respectively. Similar results have been reported by others (even in cryomilling systems) [14][15][16]. Moreover, the small white points being observed could be related to SiO 2 particle agglomerations that have not been embedded into the polymer particles.…”

“…To embrittle polymer and overcome its viscoelastic nature, ball milling of polymers was modified under cryogenic temperature, which was induced by a cryogenic medium such as liquid nitrogen. This adaptive technology is mostly referred as cryogenic mechanical alloying or cryogenic ball milling (cryomilling) [14][15][16]. Giri et al [21], in 1997, used this technique to produce polyethylene/Fe nanocomposite.…”

Real dispersion of isolated fumed silica nanoparticles in highly filled PMMA prepared by high energy ball milling

“…Very few attempts have been addressed to that direction [13][14][15] but, nanoscale blending in polymer/inorganic particles com- posites showing a completely homogeneous dispersion of the nanoparticles within the polymer matrix has never been shown.…”

Hybrid and Hierarchical Composite Materials

“…This in turn leads to a composite material where the properties of the individual components are retained, whereas depending on the degree of interaction between the filler particles and the polymer matrix, new properties may arise due to synergistic interfacial effects. (Vertuccio et al 2009;Mangiacapra et al 2006), magnetoresponsive MNP (Giri 1997;Bao and Jiang 2005;Zhu et al 2006;, and nickel-ferrite nanopowder (Azhdar et al 2008) employing cryogenic HEBM.…”
