Nacre-like ceramic composites are of importance in a wide range of applications, because of their mechanical properties, combining high mechanical strength and high fracture toughness. Those mechanical properties are the result of strongly aligned platelets glued in a matrix. Different methods exist to shape such 'brick-and-mortar' hierarchical structure. In this paper, it is proposed to use the phenomenon of heteroaggregation between silica nanoparticles and large alumina platelets. Experimental and numerical results show that silica nanoparticles can adsorb on alumina platelets with a good distribution. This adsorption promotes the deagglomeration of alumina which can self-organize in layers by sedimentation. This phenomenon can be exploited to shape alumina-silica nacre-like composites.

“…The measurements were carried out on the Rank Brothers Mark II microelectrophoresis apparatus using a flat cell equipped with platinum electrodes in a bath thermostated at 25 ± 0.1 °C. As in several previous investigations, the mobility of the fiber fines was assumed to be representative of the bulk fibers from which they were derived (Jaycock et al, 1975;Alince et al, 1978). The mobility of the latexes in a medium containing 0.05 M NaCl as supporting electrolyte was used to calculate the f potential of the particles from the Henry relation…”

“…Since this induced deposition can be regarded as a heterocoagulation process involving particles dissimilar in size and magnitude of the surface potential (Derjaguin, 1954;Hogg et al, 1966), it is understandable that it is a random, not easily controlled process. Because of this, previous studies of the interaction of latexes with cellulose fibers have been carried out in the absence of flocculant using cationic latexes (Alince et al, 1976;1978).…”

“…This may be used either as a route to extract a valuable component or as a means of purification by removing obnoxious particulates . Particle deposition also plays an important part in the manufacture of paper, textile science, ceramics, surface and powder science, and coatings technology. Adventitious deposition also results in problems such as fouling of membranes, biological systems, , and heat exchanger surfaces.…”

Deposition of Rutile Titanium Dioxide Particles onto Oppositely Charged Surfaces: A Comparison of Stagnation Point Flow and Quiescent Conditions and the Formation of Two-Dimensional “Rafts”

The rate of deposition of paint-grade rutile titanium dioxide particles (∼0.3 µm diameter) onto model substrates, under a variety of conditions, has been monitored. The model substrates used were opticallyflat glass plates, whose surfaces were made cationic by reaction with (aminopropyl)trimethoxysilane, APTMS. A flow geometry was arranged such that the particles impinged, through a jet, normally onto the substrate. This creates a stagnation point region near the substrate surface, opposite the mouth of the jet. In this region, at relatively low mass transfer rates, it is supposed that particles reach the surface by a diffusion process. The deposition (rate) of the particles was monitored visually using both a microscope and also a CCD camera linked to an image-analysis system. This allowed the number of particles deposited per unit area to be monitored. Deposition rates, and maximum coverages, have been established at various particle concentrations and various background electrolyte (NaCl) concentrations. The results obtained agreed well with experiments in which APTMS-coated glass plates were simply immersed ("vertically") in a suspension of titania particles, and particles were allowed to deposit under Brownian motion conditions. In the flow experiments, provided the NaCl concentration was below a critical value, the particles remained stable in dispersion and "isolated" on the substrate surface. However, over a certain salt concentration range, when the particles were precovered with an adsorbed layer of poly(vinyl alcohol), two-dimensional aggregation ("raft formation") was observed on the substrate surface.
