Ottadecilmetildiclorosilano

Descrizione:

Ottadecilmetildiclorosilano, con il numero CAS 18643-08-8, è un composto organosiliconico caratterizzato dalla sua lunga catena alchilica idrofobica e da un gruppo funzionale clorosilano. Questo composto appare tipicamente come un liquido incolore o giallo pallido ed è noto per la sua capacità di formare monostrati autoassemblati su vari substrati, rendendolo prezioso per applicazioni di modifica delle superfici. La sua natura idrofobica è attribuita alla catena ottadecilica (C18), che migliora la repellenza all'acqua e riduce l'energia superficiale. Ottadecilmetildiclorosilano è spesso utilizzato nella produzione di rivestimenti idrofobici, così come nella preparazione di silice funzionalizzata e altri materiali per l'uso in elettronica, biotecnologia e scienza dei materiali. Inoltre, può reagire con l'umidità per formare legami silossanici, portando alla formazione di reti di silano stabili. Sono necessarie precauzioni di sicurezza quando si maneggia questo composto, poiché può essere irritante per la pelle e gli occhi, e devono essere mantenute condizioni di stoccaggio adeguate per prevenire l'idrolisi.

Alkyl 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.
