Stabilization of gamma alumina slurry for chemical–mechanical polishing of copper

The Effect of Prewetting on the Loading of γ‐Alumina Washcoated Cordierite Monolith

“…Particle size distribution was measured on a laser particle size analyzer (Malvern E‐3600, Malvern Instruments, Worcestershire, U.K.). In 12 h of milling, the average particle size of alumina reduced from 35 to 8 μm, and to 3.5 μm in 24 h. The pH of the slurry increased from 2.5 to 3.5 during milling, most likely due to Na 2 O eluted from the inner domain of γ‐alumina particles 14 . The milled alumina was dried and stored for further use.…”

Physicochemical study of the complexation of poly(acrylic acid) with Cu2+ ions in water

“…For instance, polymer-metal complexation is used for the removal of toxic metal ions in wastewater treatment [1][2][3][4][5][6][7][8] and for the preparation of improved catalysts in catalytic reactions. [9][10][11] Moreover, the exploitation of polymermetal complexation in hydrogels or polymer-modified surfaces is very promising for several potential smart applications, such as redox actuators, 6 metal-ion-selective electrodes, [12][13][14] and electroswitchable devices. 15 The complexation of Cu 21 ions with carboxyl-containing polymers or gels, such as poly(acrylic acid) (PAA) and poly(methacrylic acid) (PMAA), has been widely studied with a variety of techniques, both in water and in the solid state.…”

“…For instance, polymer–metal complexation is used for the removal of toxic metal ions in wastewater treatment1–8 and for the preparation of improved catalysts in catalytic reactions 9–11. Moreover, the exploitation of polymer–metal complexation in hydrogels or polymer‐modified surfaces is very promising for several potential smart applications, such as redox actuators,6 metal‐ion‐selective electrodes,12–14 and electroswitchable devices 15…”

Stabilization in Water of Polymer/Cu2+ Complexes Using Poly(sodium acrylate)‐graft‐poly(N,N‐dimethylacrylamide) Graft Copolymers

“…For instance, polymer/metal complexation has been applied for the removal of toxic metal ions in waste‐water treatment1–9 or for the preparation of improved catalysts in catalytic reactions 10–13. Moreover, recently, several potential ‘smart’ applications, like redox actuators,14 metal ion selective electrodes,15–17 or electroswitchable devices18 have been proposed based on polymer/metal complexation.…”
