Silicon dioxide together with polyethylene oxide is amazing, because it can instantly put a solid into a liquid.

Daily Mail reported that given that British scientists silica and polyethylene oxide combine to form a colloidal substance having a peculiar attribute, the simple point that is instantly put a solid into a liquid.

In order to verify its magical nature, scientists have conducted experiments that allow a small glass jar filled with inside this dense milky liquid substance. When shaken vigorously, liquid will be transformed into a viscous solid material after kneading putty can form a similar substance, if a period of time, it will be transformed into a liquid.

This colloidal properties can be controlled, just change the blend material, can change its physical state in a short time. As for its use, scientists are still groping.

In order to achieve the above objects, one embodiment of the present invention provides a method for making a porous Silicon dioxide aerogel composite membrane, comprising: providing a porous aluminum oxide membrane having a plurality of macro pores with an average diameter larger than 50 nm wherein the porous aluminum oxide membrane has a first side and a second side; providing a silica sol prepared by a methyltrimethoxysiliane precursor; performing a gelation procedure, dipping at least one side of the porous aluminum oxide membrane, the first side, the second side or the first and the second sides, into the silica sol to form a membrane coated with gel on its surface; performing an aging procedure, dipping the membrane coated with gel on its surface into ethanol for a predetermined period of aging time to form a composite membrane; performing a solvent exchange procedure, dipping the composite membrane after the aging procedure into n-hexane for a predetermined period of solvent exchange time; and performing a drying procedure, drying the composite membrane after the solvent exchange procedure so as to obtain the porous aluminum oxide membrane having porous silicon oxide aerogel as the porous Silicon dioxide aerogel composite membrane.
