Strengthening Porous PVA with TiO_2 Structure by an Ice-Templating Method

A poly vinyl alcohol(PVA) scaffold with aligned porous is strengthened by in-situ combining with TiO_2. The increased freezing rate can be used to further increase the strength of aligned porous materials. The strengthened porous PVA exhibits aligned interconnected porous structures and shows a significant enhancement in tensile testing and compression strength testing.
