2013, Materials Science and Engineering CCitation Excerpt :Subsequently, Nan et al. [8] used calcium dodecyl sulfate (CDS) both as an anionic surfactant and a calcium source in their precipitation process of CaCO3; by varying the concentration of urea it was found possible to obtain pure vaterite, pure calcite or a mixture of calcite, vaterite and aragonite. Polymers, both synthetic and natural ones (especially in view of the fact that CaCO3 is a common biomineral), constitute another type of popular additives towards the same end [9–13]; in addition, some of the biopolymers have been used as heterophase templates. Biopolymers employed in biomimetic crystallization of CaCO3 include protein macromolecules isolated from mollusk shells, synthesized peptides and collagen matrices have been used as effective templates for the biomimetic crystallization of CaCO3 [14–23].

2010, Journal of Petroleum Science and EngineeringCitation Excerpt :These polymers are found to wrap the nucleus surface and inhibit crystal growth by reducing the rate of step movement across the crystal surface (surface diffusion). The adsorbed polymers may also increase the electric field around the particles, so that the double layer repulsion would also contribute to the prevention of coagulation (Rolfe, 1966; Solomon and Rolfe, 1966). As a result, the onset of crystallization is delayed and crystallization rates reduced which was evident from static and dynamic tests.
