  • Method for preparing porous hydrogel through freezing-illumination
    Patent number: 10358516
    Abstract: The present invention discloses a freezing-illumination method for preparing porous gels, comprising the steps of: (a) synthesizing the gels containing dynamic exchangeable bonds; (b) illuminating the gels under frozen state by certain wavelength light source; (c) elevating the temperature and melt the ice crystals within the gels to get the porous structure. The dynamic exchangeable bonds existing in the gels include double/multi-sulfur bond, hydrazine bond, boronic ester bond. Catalyst is also included in the gel composition to activate the bond exchange reactions under illumination. This new method for preparing porous gels is easy to operate and suitable for most kinds of gels. Meanwhile, it can spatially control the pore structure within the gels by local illumination.
