Claims13
A composition comprising solid particles of an oxide of an element selected from the group consisting of Si, Ti, Fe, Zn, and Al, wherein the solid particles each have a surface functionalized with at least one terminal cyclocarbonate group attached to the surface via a linker, wherein the at least one terminal cyclocarbonate group and the linker has the structure set forth in formula (I):
- wherein:
- n=1 or 2;
- [X] is an element selected from the group consisting of O, N, and C;
- [Y] represents an alkylene group carrying 1-20 C atoms, that can be linear, branched, or cyclic, or connected to a carbonyl or an ether group;
- q=0 or 1;
- and
- R1 is a coupling reactive group serving as a linker selected from silanes, siloxanes, phosphates or carboxylates.
