Morphogenesis of the Na3(CO3HCO3)‚2H2O Matrix-Mediated on Polyaminosiloxane Joo-Woon Lee, Wei Zhao, and J. M. White* Center for Materials Chemistry, Department of Chemistry and Biochemistry, University of Texas, Austin, Texas 78712 Received August 8, 2003. In Final Form: October 8, 2003 We report the matrix-mediated mineralization of Na3(CO3HCO3)‚2H2O at the air interface of NaOHcontaining poly(γ-aminopropyl triethoxysilane) matrixes, which are exposed to a warm and humid mixture of CO2 and air (∼37 °C; relative humidity (RH) ∼ 100%; CO2 ∼ 40 000 ppm) for
