Bearzotti, Polyethylenimine (PEI) has been grafted on a 2D hexagonal mesostructured porous silica of MCM-41 type (LUS silica) using 3-glycidoxypropyltrimethoxysilane (GTMS) as a Mesoporous silica nanoparticles (MSNs) are silica nanoparticles with pores that range in diameter from 2 to 50 nm and have an overall diameter below 1 µm. Their range of pore sizes is consistent with the IUPAC definition of mesoporous1 and make them ideal materials for applications ranging from catalysis and environmen Mesostructured materials are a fairly new type of materials having pores in the mesoscopic range of 2-50 nm. These materials have been object for an exponentially increasing number of publications since the discovery in the beginning of the 1990’s.

Mesostructured silica tubes and rods were prepared by deposition of a prehydrolysed silica sol with surfactant onto the cylindrical pores of a polycarbonate (PC) membrane template, followed by calcination to remove the surfactant and membrane template. The tubular and rodlike morphologies of mesostructured silica were demonstrated by scanning

Recently, Zhu et al. reported the synthesis of mesostructured silica tubes on a silicon substrate using the porous anodic alumina (PAA) template [ 1 Silica mesoporous SBA-15. 1 Product Result | Match Criteria: Description, Product Name Polyethylenimine (PEI) has been grafted on a 2D hexagonal mesostructured porous silica of MCM-41 type (LUS silica) using 3-glycidoxypropyltrimethoxysilane (GTMS) as a grafting agent to develop sorbents for CO 2 capture. The advantage of this tether is to create ethanolamine units upon reaction of the epoxy group with the amine functions of PEI. The “molecular stencil patterning” technique has been used to optimize at high coverage the distribution of aminopropylsilyl tethers (APS) grafted into the nanochannels of a mesostructured MCM-41 … Porous silica material with palladium clusters embedded inside is an example of a potential material for hydrogen storage.

In this study, though the fabricated tubes were oriented perpendicularly to the substrate, a strong vacuum condition was required to enter the surfactant/silica source into the pores of the PAA template.

Self‐standing films of surfactant mesostructured materials have been prepared with Mesostructured Materials and the Conversion to Porous Silica Films.

The advantage of this tether is to create ethanolamine units upon reaction of the epoxy group with the amine functions of PEI. Mesoporous silica nanoparticles (MSNs) were independently synthesized in 1990 by researchers in Japan. They were later produced also at Mobil Corporation laboratories and named Mobil Crystalline Materials, or MCM-41.
