文摘
- •
Mesoporous TiO2 (meso-TiO2) had the larger pore channel than MCM-41.
- •
Polyethylenimine (PEI) were modified on meso-TiO2 surface and inner-channel.
- •
Appropriate molecular mass of PEI treated meso-TiO2 had great barrier property.
- •
Meso-TiO2/PEI prolonged the path of water molecules diffusing into the coatings.
- •
Meso-TiO2/PEI structure enhanced epoxy coating barrier and anticorrosion property.
