A POSS-PMMA copolymer has been synthesised by conventional free-radical polymerisation reaction. Uniform electrospun fibres from this copolymer showed a water contact angle as high as 165 degrees with a sliding angle as low as 6 degrees . For the first time, we found that the electrospun fibres had a bundled nanofibril secondary structure with an ordered POSS morphology on the fibre surface.

A new hybrid material consisting of a polyhedral oligomeric silsesquioxane (POSS) and carbon nanotube (CNT) was synthesized by a simple and versatile approach entailing click coupling between azide moiety-functionalized POSS and alkyne-functionalized multi-walled CNTs. This approach provides a simple and convenient route to efficiently functionalize a wide variety of nanoscale nanostructure mat...

A coarse-grained model has been developed for simulating the self-assembly of nonyl-tethered polyhedral oligomeric silsesquioxane (POSS) nanoparticles in solution. A mapping scheme for groups of atoms in the atomistic molecule onto beads in the coarse-grained model was established. The coarse-grained force field consists of solvent-mediated effective interaction potentials that were derived via...

BACKGROUND Carbon nanotubes (CNTs) have unique physical and chemical properties. Furthermore, novel properties can be developed by attachment or encapsulation of functional groups. These unique properties facilitate the use of CNTs in drug delivery. We developed a new nanomedicine consisting of a nanocarrier, cell-targeting molecule, and chemotherapeutic drug and assessed its efficacy in vitro....

Research into polymers incorporating polyhedral oligomeric silsesquioxane (POSS) has intensified during the past several years, revealing new fundamental polymer physics, new synthetic routes, and unexpected applications. The present review article critically examines the recent scientific literature on POSS polymers with an emphasis on structure-property relationships. We conclude that it is a...

Trisilanolphenyl-polyhedral oligomeric silsesquioxane titanium (Ti-Ph-POSS) was synthesized through the corner-capping reaction, and Ti-Ph-POSS dispersed in benzoxazine (BZ) to prepare Ti-Ph-POSS/PBZ composite materials. could catalyze ring-opening polymerization (ROP) of BZ reduce curing temperature benzoxazine. In addition, Ti immobilized on cage form covalent bonds with N or O atoms polybenz...

Self-assembly of functionalized nanoscale building blocks is a promising strategy for "bottom-up" materials design. Recent experiments have demonstrated that the self-assembly of polyhedral oligomeric silsesquioxane (POSS) "nanocubes" functionalized with organic tethers can be utilized to synthesize novel materials with highly ordered, complex nanostructures. We have performed molecular simulat...

The results of Raman microspectroscopy measurements of octamethylsilsesquioxane (om-POSS) (3-wt %) in polypropylene (PP) are presented and compared with theoretical spectra calculated by ab initio density functional theory (DFT) based methods. The internal structure of this dielectric composite at the micrometer level was obtained by Computerized X-ray microtomography (CXμT) which reveals how m...

Public open spaces (POSs) provide multiple services (such as facilities for physical activities and social interactions) to local people, these are important the well-being of society improving quality life. Extensive research on POSs has been carried out in developed countries US Australia, well European including Spain, France, Germany). However, Saudi Arabian context remain unexplored. This ...
