Porosity in Polysilsesquioxane Xerogels [PDF]
MRS Proceedings, 1999 ABSTRACTPolymerization of organotrialkoxysilanes is a convenient method for introducing organic functionality into hybrid organic-inorganic materials. However, not much is known about the effects of the organic substituent on the porosity of the resulting xerogels.
