The effect of adding SiO2 on the pore structure and the color fastness to washing of PVA sponge

[摘要] The present study investigates the role of pore-forming SiO2particles on the pore structure, and color fastness following washing of a porous PVA sponge. We found that the SiO2micron particle consideration plays a decisive role on the pore-structural type and the color fastness. Moreover, the particles also influence the mechanical modulus and the water adsorption capacity.
