Abstract
The state of water in nanocomposites modeling the bone tissue and created on
the basis of nanodimensional hydroxyapatite and polypeptides (gelatin,
albumin) by the method of 1H NMR spectroscopy is studied. The state and
thermodynamic parameters of bound water was determined. It is shown that
water in composites can exist in strongly and weakly associated states. The
maximal amount of weakly associated water is registered for composites
containing albumin. It is shown that the weakly polar environment, such as
chloroform, diminishes the value of bound water in nanocomposites due of the
cluster state formation.
