Description
Summary:An original technique to obtain porous sheets from various inorganic substances (silicon dioxide, hydroxyapatite, and silver) using polymer matrices whose high-disperse structure is formed by the crazing mechanism has been described. The structure of a porous sheet and its characteristics can vary in wide ranges (the diameter of pores can vary from several nanometers to several micrometers) and depend on the matrix morphology of the initial polymer, its strain degree, and the amount of the inorganic component and the method of its introduction. The conditions needed to form a sheet are formulated: the degree of the polymer film strain should be no less than 50% and the filler content should be no less than 10 vol %.
