Macroporous silica using a “sticky” Stöber process
Abstract
The generation of macroporous silica structures using a sol–gel process generally requires the presence of high molecular weight, water-soluble polymers. We demonstrate that significantly lower molecular weight poly(ethylene glycol) (PEG) polymers can drive a particle aggregation process to generate macroporous silica. Compared to unfunctionalized PEGs (HO–PEG–HO, molecular weight > 10000 g mol−1), PEG polymers with allyl (A–PEG–A) or silyl end …
