Additive-Assisted Aqueous Synthesis of BaTiO3 Nanopowders
The effect of poly(acrylic acid) (PAA), poly(vinylpyrrolidone) (PVP), sodium dodecylsulfate (SDS), hydroxypropylmethylcellulose (HPMC), and D-fructose additives on the growth of BaTiO3 particles by aqueous synthesis is studied. Through different mechanisms, all the tested additives influenced the growth of BaTiO3. For high concentrations, PAA adsorbed on specific crystallographic faces changing...
متن کاملBiodegradation of Gelatin-g-Poly( ethyl Acrylate)
Synopsis Gelatin-g-poly(ethy1 acrylate) copolymers were prepared in an aqueous medium, using KzS20~ initiator. The composition of the graft copolymers was dependent upon temperature and duration of the reaction. The number of grafting sites was small and molecular weight of the grafted poly(ethy1 acrylate) branches was high. Three copolymer samples with grafting efficiencies of 33.3% 61.0%, and...
متن کاملCalorimetric study of block-copolymers of poly(n-butyl acrylate) and gradient poly(n-butyl acrylate-co-methyl methacrylate)
The nanophase separation in diblock and triblock copolymers consisting of immiscible poly(n butyl acrylate) (block A) and gradient copolymers of methyl methacrylate (MMA) and n butyl acrylate (n BA) (block M/A) were investigated by means of their heat capacity, Cp, as a function of the composition of the blocks M/A and temperature. In all copolymers studied, both blocks are represented by their...
متن کاملErosion Corrosion of Carbon Steel in Aqueous Slurries
Erosion corrosion of an usual carbon steel in a variety of aqueous slurries of 10% Al2O3 powder composed of 0.1M NaOH, concentrated cooling water (synthetic rather than natural), 3% NaCl, and 0.01M HCl was investigated from the electrochemical point of view. The total weight loss, Wt, was experimentally divided into the following three terms: the mechanical loss, Wm, the corrosion loss, Wc, and...
متن کاملNovel RAFT amphiphilic brush copolymer steric stabilisers for cubosomes: poly(octadecyl acrylate)-block-poly(polyethylene glycol methyl ether acrylate).
Copolymers, particularly Pluronics®, are typically used to sterically stabilise colloidal nanostructured particles composed of a lyotropic liquid crystalline bicontinuous cubic phase (cubosomes). There is a need to design and assess new functionalisable stabilisers for these colloidal drug delivery systems. Six amphiphilic brush copolymers, poly(octadecyl acrylate)-block-poly(polyethylene glyco...
