Hybrid materials with superior structural and functional properties can be obtained by incorporating nanofillers into polymer matrices. Polyhedral oligomeric silsesquioxane (POSS) nanoparticles have attracted much attention recently due to their nanometer size, the ease of which these particles can be incorporated into polymeric materials and the unique capability to reinforce polymers. We revi...

Electrospun aggregation-induced emission (AIE)-active polyhedral oligomeric silsesquioxane (POSS)-based copolymer films exhibit an approximately 9-fold increase in response to explosive vapors compared to dense films although porous copolymer films have a thickness as high as 560 ± 60 nm.

We present a simple approach towards highly efficient solid-state luminophores with strong deep blue emission and a record high photoluminescence quantum yield of 60% by embedding water-soluble N,S-co-doped carbon dots into a polyhedral oligomeric silsesquioxane (POSS) matrix.

Quaternary ammonium functionalized polyhedral oligomeric silsesquioxane (OctaAmmonium-POSS) units, widely employed as additives in ceramic and polymeric systems, possess many attributes which make them attractive as biocompatible drug carriers: nanoscale size, three-dimensional functionality, efficient cellular uptake, low toxicity, and high solubility.

In this work, polyhedral oligomeric silsesquioxane (POSS) with two different functional groups, octa(nitrophenyl)silsesquioxane (ONPS) and octa(aminophenyl)silsesquioxane (OAPS), was incorporated polydimethylsiloxane (PDMS), forming composite membranes for furfural recovery via pervaporation process. The addition of POSS had enhanced the hydrophobicity PDMS improved affinity membranes. At same ...

Abstract In this work, octamercapto polyhedral oligomeric silsesquioxane (POSS-8SH) and octaphenol (POSS-8Phenol) were successfully synthetized. POSS-8Phenol was added into the synthesis process of liquid thermoset phenolic resin (PR) to obtain POSS-modified (POSS-PR). Chemical structures POSS-8SH, POSS-8Phenol, POSS-PR confirmed by FTIR 1 H-NMR. TG DTG analysis under different atmosphere showe...

As scientific literature considers polyhedral oligosilsesquioxanes (POSS) as potential drug delivery systems, it is necessary to check their impact on mammalian cells. Toxicity of octaammonium chloride salt of octaaminopropyl polyhedral oligomeric silsesquioxane (oap-POSS) towards two cell lines: mouse neuroblastoma (N2a) and embryonic mouse hippocampal cells (mHippoE-18) was studied. Experimen...

Polyacrylic acid/ octavinyl polyhedral oligomeric silsesquioxane, nanocomposite hydrogel with 3-D network was synthesized via radical polymerization. Octavinyl polyhedral oligomeric silsesquioxane was used as crosslinker and nanofiller simultaneously in the preparation of the hydrogel. Hydrogel adsorption performance was determined by adsorption of methylene blue. The adsorption capacity was ev...

The conventional fabrication of antifogging polymer coatings such as zwitterionic or amphiphilic copolymers typically require multiple processes. In this work, a simple photocuring method was used to create series containing polyhedral oligomeric silsesquioxane (POSS) without the need prepare copolymer. Surface analysis demonstrated that coating thickness about 6 μm, and surface POSS content sh...

Moisture-curable polyurethane (MCPU) is a specifically designed material for the consolidation of fragile cultural objects in high-humidity environments. In order to solve problem its susceptibility yellowing due heat ageing, polyhedral oligomeric silsesquioxane (POSS) was added MCPU prepare POSS/MCPU. The appearance, stability and mechanical properties POSS/MCPU films were characterized using ...
