What is the relation between the average pore size and water absorption property of the hydroxyapatite scaffold prepared by varying the percentage of hydroxyapatite and binder? It is found that lower hydroxyapatite content scaffold possess the maximum porosity with larger pore size and lowest water absorption, whereas highest hydroxyapatite content scaffold has the lowest porosity with smaller pore size and maximum water absorption. what may be the probable correlation between the,m?
The greater the specific surface area of m2 / g (the smaller the pore), the more water molecules will be adsorbed. This is the general position of surface thermodynamics.
The average pore size is proportional to the particle porosity and inversely proportional to the specific surface area and particle density. Regards,
