## Abstract A hybrid of poly(2‐hydroxyethylmethacrylate) (pHEMA), a polymer widely employed for biomedical applications, and silica gel, exhibiting a well‐known bioactivity, was produced by sol‐gel. The amount of the inorganic precursor, tetraethoxysilane (TEOS), was mixed to the organic monomer, s
## Abstract **Summary:** Silica sols were first prepared based on different ratios of tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) by an acid‐catalyzed sol–gel process, and then incorporated into acrylic‐based polyurethanes. The structures and morphologies of silicone‐oxo clusters were
