Feniltrietoxisilano

Descrição:

Feniltrietoxisilano, com o número CAS 780-69-8, é um composto organossilícico caracterizado por sua estrutura de silano, que inclui um grupo fenila e três grupos etóxido ligados a um átomo de silício. Este composto é tipicamente um líquido incolor a amarelo pálido e é conhecido por sua capacidade de se ligar a materiais orgânicos e inorgânicos, tornando-o útil como agente de acoplamento e modificador de superfície. Apresenta boa estabilidade térmica e propriedades hidrofóbicas, o que aumenta sua aplicabilidade em várias formulações, incluindo revestimentos, adesivos e selantes. Além disso, Feniltrietoxisilano pode melhorar a adesão de polímeros orgânicos a substratos inorgânicos, como vidro e metais, devido à sua funcionalidade de silano. Sua reatividade permite que ele sofra hidrólise na presença de umidade, levando à formação de grupos silanol que podem polimerizar ou se ligar a superfícies. No geral, este composto é valorizado em indústrias como construção, eletrônica e ciência dos materiais por sua versatilidade e eficácia em melhorar as propriedades dos materiais.

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.
