Embodiment 1
[0023] A preparation method of nano-bone scaffold composite material, comprising the steps of:
[0024] (1) Preparation of biphasic calcium phosphate nanopowder: 0.4M Ca(NO 3 ) 2 4H 2 O solution and 0.2M (NH 4 ) 2 HPO 4 The solution was added into a three-necked flask according to the calcium-phosphorus molar ratio of 1.65:1, stirred and mixed evenly, and then the pH was adjusted to 11 with 25% ammonia water to obtain a white powder precipitate. After filtering, the white powder was washed with deionized water. Then dry it at 100°C, put it into a muffle furnace for roasting, first raise the temperature to 1125°C at a rate of 10°C / min, keep it for 1 hour, then lower it to room temperature with the furnace, then take it out and grind it, and finally pass it through a 200-mesh sieve to obtain a two-phase Calcium phosphate nanopowder;
[0025] (2) prepare hydroxyethyl chitosan: get 10g chitosan and join in the 50wt% sodium hydroxide solution of 16.7g and carry out alkalizati...
Embodiment 2
[0029] A preparation method of nano-bone scaffold composite material, comprising the steps of:
[0030] (1) Preparation of biphasic calcium phosphate nanopowder: 0.4M Ca(NO 3 ) 2 4H 2 O solution and 0.2M (NH 4 ) 2 HPO 4 The solution was added into a three-necked flask according to the calcium-phosphorus molar ratio of 1.60:1, stirred and mixed evenly, and then the pH was adjusted to 11 with 25% ammonia water to obtain a white powder precipitate. After filtering, the white powder was washed with deionized water. Then dry it at 100°C, put it into a muffle furnace for roasting, first raise the temperature to 1125°C at a rate of 10°C / min, keep it for 1 hour, then lower it to room temperature with the furnace, then take it out and grind it, and finally pass it through a 200-mesh sieve to obtain a two-phase Sodium Phosphate
[0031] rice powder;
[0032] (2) prepare hydroxyethyl chitosan: get 10g chitosan and join in the 50wt% sodium hydroxide solution of 16.7g and carry out ...
Embodiment 3
[0036] A preparation method of nano-bone scaffold composite material, comprising the steps of:
[0037] (1) Preparation of biphasic calcium phosphate nanopowder: 0.4M Ca(NO 3 ) 2 4H 2 O solution and 0.2M (NH 4 ) 2 HPO 4 The solution was added into a three-necked flask according to the calcium-phosphorus molar ratio of 1.55:1, stirred and mixed evenly, and then the pH was adjusted to 11 with 25% ammonia water to obtain a white powder precipitate. After filtering, the white powder was washed with deionized water. Then dry it at 100°C, put it into a muffle furnace for roasting, first raise the temperature to 1125°C at a rate of 10°C / min, keep it for 1 hour, then lower it to room temperature with the furnace, then take it out and grind it, and finally pass it through a 200-mesh sieve to obtain a two-phase Calcium phosphate nanopowder;
[0038] (2) prepare hydroxyethyl chitosan: get 10g chitosan and join in the 50wt% sodium hydroxide solution of 16.7g and carry out alkalizati...
