Young’s modulus of PS/CeO2 composite with core/shell structure microspheres measured using atomic force microscopy

Polymethylmethacrylate (PMMA)/CeO 2 hybrid particles for enhanced chemical mechanical polishing performance

“…According to the existing literatures [16,28], the compressive Young's moduli of a variety of the polymer colloids (PS or PMMA) and the core-shell organic/inorganic hybrid particles (PMMA/SiO 2 , PS/SiO 2 and PS/CeO 2 ) were determined using AFM nanoindentation technique. The reported results confirmed that the moduli of the hybrid particles were much lower than those of inorganic shell materials and much close to those of their polymer cores.…”

“…Besides, the highest MRR was observed for the largest diameter cores combined with the smallest silica particles. In our previous work [14][15][16], the hybrid particles with polystyrene (PS) as a core and CeO 2 nanoparticles as a shell were prepared by in-situ decomposition reaction of Ce(NO 3 ) 3 on the surfaces of the negatively charged PS spheres. Oxide-CMP behaviors and elastic moduli of the PS/CeO 2 hybrid particles were evaluated by atomic force microscopy (AFM).…”

Atomic force microscopy indentation to determine mechanical property for polystyrene–silica core–shell hybrid particles with controlled shell thickness

“…Besides, Zhang et al [32] investigated the mechanical properties of hollow silica spheres (15-70 nm in shell thickness), and the calculated Young's modulus (18 ± 6 GPa) was about 4 times smaller than that of fused silica (72 GPa [33]). In our previous work [34], the elastic deformation of the PS/CeO 2 composites deposited on a rigid substrate was evaluated by measuring the AFM force curve technique.…”

Waterborne Acrylic/CeO2 Nanocomposites for UV Blocking Clear Coats

“…In this direction, in the last decade, many authors have studied the benefits in properties that could be obtained when combining CeO 2 nanoparticles with polymers. For instance, catalytic [1][2][3], thermal [4], mechanical [5,6], optical [7][8][9], anticorrosion [10][11][12], and barrier properties [13] of polymers have been considerably improved with the incorporation of CeO 2 nanoparticles. Moreover, CeO 2 nanocomposites can find application in many different fields such as chemisensors and photocatalyst for environmental applications [14][15][16], temperature and humidity sensors [17] or extractants for yttrium ions [18].…”
