Introduction to Poss Nanoparticles

What is/are Poss Nanoparticles?

Poss Nanoparticles - The results of molecular dynamics (MD) simulation show that POSS nanoparticles can improve the mechanical properties (bulk modulus, Young's modulus and shear modulus) of the epoxy at low temperature. ^[1] Highly CO2-philic POSS nanoparticles contribute to scCO2 foaming as cell nucleators enhancing the foaming performance of the syntactic composites. ^[2] Overall, it was concluded that the use of A-POSS nanoparticles in NR composites can be alternative to RFL dipping method currently being used in the tire industry due to enhanced adhesion between rubber composites and the polyamide cords. ^[3] Finally, the experimental results showed that the addition of OvPOSS nanoparticles can obviously increase the inception voltage of treeing growth and suppress the treeing propagation under 30 kV pulse voltage due to the introduction of deep traps in the OvPOSS/PP nanocomposites. ^[4] POSS nanoparticles functionalized using pre-cured epoxy were first embedded in an epoxy matrix and the resulting nanocomposites were then cured to a conversion ratio of 87 %. ^[5] POSS nanoparticles can be introduced into hydrogels via simple and easy methods such as physical blending, ionic interaction and covalent bonding to prepare POSS hybrid hydrogels with the rigidity of inorganic materials and the processability of organic materials. ^[6] In this chapter, we describe the synthesis, characterization, and properties of various POSS nanoparticles including nonreactive, monofunctional, bifunctional, and multifunctional POSS derivatives. ^[7] Here, an optical microscope was employed to study the change rule in the 8-NH2-POSS/PSA nanocomposite membrane formation process due to the addition of 8-NH2-POSS nanoparticles. ^[8] In order to improve the compatibility between the nanofillers and matrix, PLLA chains were grafted onto the POSS nanoparticles via microwave-assisted ring opening polymerization (ROP). ^[9] When there are enough POSS nanoparticles, it can effectively protect the combustion of internal polymers. ^[10] The results show that incorporation of POSS can obviously improve the dispersion and compatibility of RMAPP in FR PP system through coating of POSS nanoparticles on surface of big RMAPP FR particles. ^[11] Here, the influence of alkyl group on O2 transmission and chain dynamics was investigated by dispersing octamethyl-POSS nanoparticles (me-POSS) in LDPE. ^[12] The effect of Graphene Oxide (GO) and POSS nanoparticles on the Reverse Osmosis (RO) desalination performance of Mixed Matrix Membranes (MMMs) was investigated experimentally. ^[13] In addition, the anti-bacterial property of PA reverse osmosis (RO) membranes extremely enhanced after armoring with POSS nanoparticles. ^[14] Morphological observations (TEM and EDX) showed that POSS nanoparticles have a good dispersion state throughout the matrix and localize in both phases and also at the blend interface. ^[15] In this study, the functionalized POSS nanoparticles were used to modification of PEI-based nanofiltration membranes for Pb+2 and Cu+2 ions removal from water. ^[16] The introduction of functional POSS nanoparticles increased the strength and toughness of the matrix simultaneously, and formed the porous fiber structure. ^[17] Predominance of phthalocyanine macrocycles in the nodes of the matrix network is suggested; a satisfactory dispersion and a quasi-regular distribution of POSS nanoparticles have been revealed. ^[18] Furthermore, the first thermal decomposition temperature of the pure PVC, due to the emission of HCl, increased from 290 to 306 °C, that is, the MA-POSS nanoparticles had a retarding effect on the decomposition of the PVC matrix. ^[19] The presence of POSS leads to an increase in the number of nucleation sites, and a reduction in the size of the crystallite and the overall degree of crystallinity, as a result of the confinement of PCL chains caused by POSS nanoparticles. ^[20] Potentiodynamic polarisation measurements also indicated that the coating containing POSS nanoparticles has an improved protection efficiency. ^[21] Hygrothermal stability test showed that the shrinkage temperature (Ts) of THPS tanned leather was obviously increased with the introduction of POSS-NH2, implying that THPS and POSS nanoparticles had synergistic effect in the combination tanning process. ^[22] POSS nanoparticles were melt mixed with LDPE using a twin-screw extruder and adding up to 10 wt% POSS. ^[23] Incorporation of OA-POSS nanoparticles with various feed ratio into the second network not only led to form strong coordination interactions but also in comparison to the other Alg/PAAm gels demonstrated superior mechanical properties. ^[24] All grafted POSS nanoparticles changed from solid powders to liquid at room temperature. ^[25] By copolymerization POSS nanoparticles can be grafted onto the polymer chains of the SLR matrix. ^[26] Haze of coatings increases when POSS nanoparticles are present. ^[27] In this study, a series of poly(l-lactide) and (3-amino)-propylheptaisobutyl cage silsesquioxane (PLLA-AMPOSS) intermediates were first fabricated using single-arm in situ solution polymerization of LLA monomers and AMPOSS nanoparticles with different contents, 0. ^[28] Bioactivity and osteogenic effects of the POSS nanoparticles were investigated with cytocompatibility, cell proliferation, alkaline phosphatase activity, osteocalcin production and biomineralization assays. ^[29]
