STUDY ABOUT C-S-H WITH HIGH C/S RATIO SYNTHESIZED BY COMPLEX POLYMERIZATION METHOD

Polymer Fluoride Sensors Synthesized by RAFT Polymerization.

A series of polymer chemosensors containing naphthalimide signal moiety and imide recognition moiety for the selective detection of fluoride ions (F(-) ) were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymer chemosensors display obvious absorption and fluorescence variations upon the addition of F(-) , which can be observed by both naked eyes an...

Synthesis of Ba1-xCaxTiO3 by Complex Polymerization Method (CPM)

preparation and characterization of hyperbranched polystyrene nanocomposite synthesized by living radical polymerization and solution intercalation method

a copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )nmp). n-bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group. this brominated copolymer was used as macro initiators for atom transfer  radical  polymerization  (atrp).  chemical  modifcation  of  the  clay  and transformation of...

Polymer – Coated Ferrite Nanocomposites Synthesized by Plasma Polymerization

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisat...

Identification of viscoelastic C-S-H behavior in mature cement paste by FFT-based homogenization method

a r t i c l e i n f o A powerful and robust numerical homogenization method based on fast Fourier transform (FFT) is formulated to identify the viscoelastic behavior of calcium silicate hydrates (C-S-H) in hardened cement paste from its heterogeneous composition. The identification is contingent upon the linearity of the creep law. To characterize cement paste microstructure, the model develope...
