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).

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
