Abstract

The present invention includes an apparatus for generating an inorganic polymer electret in a colloidal state, the inorganic electret in a colloidal state itself, and applications for the inorganic electret in a colloidal state. The invention includes a method for generation of a colloidal silica particle which is dipolar in that it is positively charged in the nucleus and negatively charged on the outer surface leaving a net negative charge to the particle. The apparatus includes the ability to control particle size, uniformity, consistency, hydration, and three dimensional structure which is desirable for various applications.

Claims (9)

1. An inorganic silicate polymer electret in a colloidal state with a zeta potential between about 33 and 50 mV, said inorganic polymer electret in a colloidal state is formed by prolonged flow through a counter current device, said flow generating a charge effect, which generates multiple bi-directional magnetic fields and an electrostatic charge on the adjacent moving charged colloid particles moving in the counter current flow, resulting in the inorganic silicate polymer electret in a colloidal state.

2. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 34 and 50 mV.

3. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 34 and 48 mV.

4. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 35 and 45 mV.

5. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 36 and 43 mV.

6. The inorganic polymeric electret in a colloidal state of claim 1 wherein the zeta potential is between about 37 and 41 mV.

7. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 37 and 39 mV.

8. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is between about 37 and 38 mV.

9. The inorganic polymer electret in a colloidal state of claim 1 wherein the zeta potential is about 37.7 mV.
