Application:

Fabrication of silicone modified polyurethane matrix superhydrophobic coating with hydroxy-terminated polydimethylsiloxane modified SiO2 nanoparticles: This study uses hydroxy-terminated PDMS as a modifier to hydrophobically modify SiO2 nanoparticles (Y Cui, Y Li, D Huan, D Zeng, Y Yang, 2022 ).

High glass transition temperature shape‐memory materials: Hydroxyl‐terminated polydimethylsiloxane‐modified cyanate ester: Hydroxyl-terminated PDMS is used to modify cyanate ester, enhancing shape-memory properties (Z Li, J Hu, L Ma, H Liu, 2020 ).

The preparation and properties study of polydimethylsiloxane-based coatings modified by epoxy resin: This research explores modifying hydroxyl-terminated PDMS with siliconized epoxy resin for improved coating properties (C Zhou, R Li, W Luo, Y Chen, H Zou, M Liang, 2016 ).

Synthesis and structure of calcium silicate hydrate (CSH) modified by hydroxyl-terminated polydimethylsiloxane (PDMS): Hydroxyl-terminated PDMS is used to modify CSH, enhancing its properties for construction applications (Z Zhu, Z Wang, Y Zhou, Y Wei, A She, 2021 ).

Crosslinked polymer networks of poly (ethylene glycol) (PEG) and hydroxyl terminated poly (dimethyl siloxane) (HTPDMS) as polymeric phase change material: This study develops PEG and hydroxyl-terminated PDMS crosslinked networks for phase change materials (S Sundararajan, AB Samui, PS Kulkarni, 2019 ).
