Hydroxy terminated polydimethylsiloxane pdms oh

Before the synthesis, all glassware utilized in the procedure was thoroughly washed with isopropyl alcohol, rinsed with distilled water, and dried with absorbent paper to eliminate potential impurities.
The used reagents for the experimental procedures were isopropyl alcohol (99% Sigma Aldrich, Saint Louis, MO, USA), titanium isopropoxide (TTIP) (97% Sigma Aldrich^®), ethyl alcohol (Meyer^® Mexico City, Mexico), tetraethylorthosilicate (TEOS) (98% Sigma Aldrich^®), ammonium hydroxide (NH₄OH) (28% J.T.Baker^®, Madrid, Spain), dimethyl ketone (99.5%, Meyer^®) hydroxy-terminated polydimethylsiloxane (PDMS-OH) (2550–3570 cSt, Sigma Aldrich^®), and dibutyltin dilaurate (DBTL) (95% Sigma Aldrich^®).
