PELCO® Hydrophilic and Hydrophobic Silicon Nitride Membrane Surfaces
親水性/疏水性氮化硅支持膜
15nm, 50nm and 200nm membrane thickness
 | Silicon Nitride membranes have been modified using Atomic Layer-Deposited （ALD） techniques to change their surface properties. Depending on the process used, both Hydrophilic and Hydrophobic substrates have been created with the following advantages:
Hydrophilic surfaces enhance wetting and dispersion of aqueous solutions. This avoids particle aggregation effects commonly observed on less hydrophilic surfaces. Particularly useful in water based sols and life science applications. |
| Both coatings are available on 50nm and 200nm Silicon Nitride Membranes with a 0.5 x 0.5mm window and 15nm Si3N4 membrane with 9 each 0.1x0.1nm windows on a 200µm silicon frame with a diameter of 3mm, compatible with all standard TEM grid holders. Both sides of the membrane and frame are coated. We advise to handle the discs by gripping at the edge. | |
Specifications:
- Hydrophilic: 5nm atomic layer-deposited hydroxylated alumina on 15, 50 and 200nm ultra-low-stress silicon nitride membrane
- Hydrophobic: 5nm atomic layer-deposited alumina and fluoro-methyl-silane on 15, 50 and 200nm ultra-low-stress silicon nitride membrane
