Abstract

Sposób wytwarzania materiału kompozytowego chitozan/hydroksyapatyt/krzemionka, przeznaczonego na substytuty kości, polega na tym, że roztwór wodny soli chitozanowej, jak octan, chlorek, mleczan lub cytrynian chitozanu miesza się z nanoproszkiem hydroksyapatytowym oraz ewentualnie z glicerofosforanem wapnia, za pomocą ultradźwięków do uzyskania homogenicznej pasty, którą następnie wprowadza się do zolu kwasu metakrzemowego, całość miesza się, po czym otrzymany kompozyt suszy się konwekcyjnie w temperaturze 50 - 100°. Odmiana sposobu wytwarzania materiału kompozytowego chitozan/hydroksyapatyt/krzemionka, przeznaczonego na substytuty kości, charakteryzuje się tym, że sól chitozanową jak octan, chlorek, mleczan lub cytrynian chitozanu miesza się z roztworem wodnym octanu wapnia i roztworem wodnym wodorofosforanu sodu, po czym do otrzymanej mieszaniny wprowadza się zol kwasu metakrzemowego, zawierający roztwór wodny fosforanu sodu i trifosforanu pentasodowego, następnie całość miesza się, po czym otrzymany kompozyt suszy się konwekcyjnie w temperaturze 50 - 100°C.The method of producing the chitosan / hydroxyapatite / silica composite material for bone substitutes is that the aqueous solution of the chitosan salt, such as acetate, chloride, lactate or chitosan citrate is mixed with hydroxyapatite nanopowder and, optionally, with calcium glycerophosphate, using ultrasounds to obtain the homogeneous paste, which is then introduced into the metasilic acid sol, is mixed, after which the resulting composite is dried by convection at a temperature of 50-100 °. A variation of the method for producing the chitosan / hydroxyapatite / silica composite material for bone substitutes is characterized in that the chitosan salt such as acetate, chloride, lactate or chitosan citrate is mixed with an aqueous solution of calcium acetate and an aqueous solution of sodium phosphate, and then into the resulting mixture metasilicic acid sol, containing an aqueous solution of sodium phosphate and pentasodium triphosphate, is introduced, then the whole is mixed, after which the obtained composite is convective dried at 50 - 100 ° C.
