Synthesis and properties of new poly(dimethylsiloxane) nanocomposites

Synthesis of Nanocomposite Hybrids

“…An organic surfactant like oleic acid or oleyl amine was used to prevent the Ni nanoparticles from agglomeration. In this case, small and uniform nanoparticles can be manufactured [3]. A series of CV measurements was performed to investigate the electrocatalytic performance of the prepared Pd-decorated C60 NRs in a blank nitrogen-bubbled KOH solution to determine the electrocatalytic area (non-decorated C60 NRs showed no catalytic activity in agreement with previous reports.…”

“…For these purposes we are focused on addressing this problem by introducing a new versatile polymer ligand prepared by catalytic chain transfer polymerization (CCTP) technique, where the interaction between the polymer ligands and NCs is increased by the presence of multiple anchor groups and outer double bond functionality. Metal-based nanoparticles, such as palladium, platinum, or their alloys, have been frequently used as electrocatalysts by anchoring them on carbonbased support [1], [2] and [3]. The performance of such a hybrid catalyst depends on two main issues: (i) the properties of the catalyst -involving the activity of the metal catalyst and the overall electroactive area; (ii) the properties of the support -involving processes such as fuel diffusion (for fuel cell application), good anchoring of catalysts to the support ensuring both long-term stability and efficient electron conductivity, and finally a good electron bulk conductivity of the support to efficiently transfer the electrons to the electrode.…”

PP‐based nanocomposites with various intercalant types and intercalant coverages

“…Currently, there are three different main approaches to the preparation of PP-based PNCs: the solution process [5][6][7], in-situ polymerization [8 -10], and melt compounding [11][12][13][14][15][16]. In fact, melt compounding has proved to be an excellent technique because of its ease, versatility, and benign character, with respect to the environment.…”

Magnetic Properties of Nanoparticles

“…In using this technique, binary alloys of varying composition were studied as they cooled and the arrest points were recorded and plotted on a temperature -composition (phase) diagram. The cooling curve method is useful for commercial applications for a number of reasons: it is simple, inexpensive and provides consistent results [5].…”
