Feniltrietossisilano

Descrizione:

Feniltrietossisilano, con il numero CAS 780-69-8, è un composto organosiliconico caratterizzato dalla sua struttura di silano, che include un gruppo fenile e tre gruppi etossido attaccati a un atomo di silicio. Questo composto è tipicamente un liquido incolore o giallo pallido ed è noto per la sua capacità di legarsi sia a materiali organici che inorganici, rendendolo utile come agente di accoppiamento e modificatore di superficie. Mostra una buona stabilità termica e proprietà idrofobiche, che ne migliorano l'applicabilità in varie formulazioni, tra cui rivestimenti, adesivi e sigillanti. Inoltre, Feniltrietossisilano può migliorare l'adesione dei polimeri organici a substrati inorganici, come vetro e metalli, grazie alla sua funzionalità di silano. La sua reattività gli consente di subire idrolisi in presenza di umidità, portando alla formazione di gruppi silanolo che possono ulteriormente polimerizzare o legarsi a superfici. In generale, questo composto è apprezzato in settori come costruzione, elettronica e scienza dei materiali per la sua versatilità ed efficacia nel migliorare le proprietà dei materiali.

Arylsilane Cross-Coupling Agent
The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
Aromatic Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
