Polyacrylate/silica nanocomposite was prepared by sol–gel process via in situ emulsion polymerization. The influence of the synthetic conditions, such as the ratio of different monomers and the contents of tetraethoxysilane (TEOS), c-methacryloxypropyltrimethoxysilane (Z-6030), diethanolamine (DAM) and ammonium persulfate (APS) on the physical mechanical properties of polyacrylate/silica nanoco...

In this paper,the preparation of nano silica sol was used TEOS hydrolysis. Silica sol was used to compound the SiO2 sol / polyacrylate with acrylate monomer emulsion polymerization, the effect of sol amount and feeding methods of polyacrylate stability and other property of SiO2 / polyacrylate were studied.

Water soluble graphene with various chemical- and biofunctionalities is essential for their different applications. However, exfoliated graphenes are insoluble in water and water soluble graphene oxide precipitate if they are chemically reduced to graphene. We have developed a polyacrylate coating method for graphene oxide and then chemically reduced it into graphene. We found that polyacrylate...

The thermal degradation behaviour of polyacrylate and its zinc oxide composites were investigated by differential scanning calorimetry (DSC), thermogravimetry (TG) and Fourier transform infrared spectroscopy (FTIR). Reaction mechanisms of polymer degradation with and without ZnO particles were obtained. Filler-free polyacrylate exhibited one DSC peak, indicating that the polymer was degraded wi...

Copper is an essential metal for life, but toxic at high concentrations. In mammalian cells, two copper transporters are known, CTR1 and CTR2. order to gain insights on the possible influence of import pathway cellular responses copper, challenges were compared: one with ion, which likely use preferentially CTR1, a copper-polyacrylate complex, will be internalized via endosomal A model system c...

We compared the acute toxicity of nanosilica and polyacrylate/nanosilica instillation in Wistar rats (n = 60). Exposure to nanosilica and polyacrylate/nanosilica showed a 30% mortality rate. When compared with saline-treated rats, animals in both exposure groups exhibited a significant reduction of PO2 (P < 0.05) at both 24 and 72 hr. after exposure. Both exposure groups exhibited a significant...

A detailed in situ scattering study has been carried out on the formation of amorphous calcium carbonate (ACC) particles modulated by the presence of small amounts of sodium polyacrylate chains. The work is aiming at an insight into the modulation of ACC formation by means of two polyacrylate samples differing in their molecular weight by a factor of 50. The ACC formation process was initiated ...

Abstract Compacted clay is an effective and economical engineering barrier for seepage prevention gas blocking in landfills (including tailings pond, landfill, etc.). In addition to the lack of durability such as desiccation cracks compacted modified by clinoptilolite sodium polyacrylate, it also necessary consider changes properties water holding capacity, resistance, strength clay. Therefore,...

The goal of this study was to compare volumetric analysis in computed tomography (CT) with the length measurement prescribed by the Response Evaluation Criteria in Solid Tumors (RECIST) for a system with known mass and unknown shape. We injected 2 mL to 4 mL of water into vials of sodium polyacrylate and into disposable diapers. Volume measurements of the sodium polyacrylate powder were able to...
