- •
The surface functionalization engineering of SBA-15 was developed.
- •
The internal amino groups changed the adsorption conformation of PEG chains.
- •
The external methyl groups restrained the spillover of PEG molecules.
- •
The fusion enthalpy of PEG/SBA-15 composite was adjusted from 0 J/g to 88.2 J/g.
