Assessment of biocompatibility of ureasil-polyether hybrid membranes for future use in implantodontology
(2016-09-01)
The biocompatibility of ureasil-polyether hybrid materials has been tested for future application as membrane barrier. The authors evaluated ureasil-polyether hybrids membranes with different swollen behaviors: more swellable ...
Development of ureasil-polyether membranes for guided bone regeneration
(Iop Publishing Ltd, 2017-02-01)
The aim of this study was to develop a new barrier membrane from ureasil-polyether hybrid materials for guided bone regeneration. The membrane was prepared via the sol-gel route by using polyethylene oxide and polypropylene ...
Fine-tuning of a nanostructure, swelling, and drug delivery profile by blending ureasil-PEO and ureasil-PPO hybrids
(Royal Soc Chemistry, 2014-01-01)
Urea-cross-linked polyether-siloxane hybrid blends with tuneable hydrophilic/hydrophobic features were prepared from a mixture of poly(ethylene oxide) (PEO1900) and poly(propylene oxide) (PPO2000), hybridized by end-chain ...
Structure and properties of Ti4+-Ureasil organic-inorganic hybrids
(2006-06-08)
Hybrid planar waveguides were prepared from Ti4+-acetylacetone (acac)-Ureasil sols deposited on glass substrates. Structural features have been investigated by spectroscopic measurements (Fourier Transform Infrared ...

Transparent polysilsesquioxane films obtained from bridged ureasil precursors: Tunable photoluminescence emission in the visible region and filtering of UV-radiation
(Wiley VCH Verlag, 2010-11)
Bridged ureasil precursors were synthesized by the reaction of either ethylenediamine (1 mol) or m-xylylenediamine (1 mol) with isocyanatepropyltriethoxysilane (2 mol). Transparent polysilsesquioxane films were obtained ...
Controlled Drug Release from Ureasil-Polyether Hybrid Materials
(Amer Chemical Soc, 2009-02-10)
Flexible, transparent, and insoluble urea-cross-linked polyether-siloxane hybrids presenting a tunable drug delivery pattern were prepared using the sol-gel method from PEO (poly(ethylene oxide)) and PPO (poly(propylene ...
