| Popis: |
A nanocomposite reinforced with a 3D, connected, stiff framework should offer better performance than a simple dispersion of nanoparticles. Monolithic porous silica can be used as this framework by providing a fully connected but open porous supporting skeleton for reinforcing organic polymers. Infusion of epoxy resin into silica aerogel pores may produce a bicontinuous material that more efficiently exploits the intrinsic properties of each solid phase: bicontinuous aerogel and polymer matrix component. Matrix infusion into an aerogel monolith in principle allows greater silica content than shear mixing (of particles) which is limited by aggregation and high shear viscosities. Silica content is maximised by producing aerogels of unusually high envelope density (0.2 g.cm⁻³ – 0.8 g.cm⁻³). |
