Abstract
Official abstract text for this publication.
The invention relates to an ultralong hydroxyapatite nanowire/microwire, a method of preparing the same, a hydroxyapatite paper comprising the same and a preparation method thereof, and provides an ultralong hydroxyapatite nanowire/microwire having a length of tens to hundreds of micrometers and a diameter of tens to hundreds of nanometers. There is also provided a method of preparing the ultralong hydroxyapatite nanowire/microwire, a hydroxyapatite paper comprising the ultralong hydroxyapatite nanowire/microwire, and a method of preparing the hydroxyapatite paper.
First claim
Opening claim text (preview).
What are claimed are as follows: 1. A hydroxyapatite paper comprising an ultralong hydroxyapatite nanowire/microwire having a length of tens to hundreds of micrometers and a diameter of tens to hundreds of nanometers. 2. A method of preparing the hydroxyapatite paper of claim 1 , comprising the following step: dispersing an ultralong hydroxyapatite nanowire/microwire having a length of tens to hundreds of micrometers and a diameter of tens to hundreds of nanometers in a solvent, followed by forming, separation, drying and pressing to obtain the hydroxyapatite paper. 3. The method of claim 2 , wherein the solvent is water or an alcohol, wherein the alcohol includes ethanol, methanol, propanol, isopropanol and butanol. 4. The method of claim 2 , wherein the method further comprises adding additives to the solvent, wherein the additives include inorganic additives and organic additives, wherein the inorganic additives include sodium silicate, potassium silicate, sodium borate and potassium borate; and the organic additives include polylactic acid, polyethylene glycol, polyvinyl alcohol, polystyrene and polyurethane. 5. The method of claim 2 , wherein the separation includes filtration and vacuum filtration, and the temperature for drying is 20-200° C.
