Bionanocomposites gelatin

In another study Feng et al. [86] presented the stmcture and properties of new thermoforming bionanocomposites based on chitin whiskers-graft-polycaprolac-tone. The synthesized material was characterized by FTIR, SEM, TEM and XRD. The surface and mechanical properties were also determined and discussed. Ha-riraksapitak et al. [87] prepared a neat hyaluronan-gelatin scaffolds and chitin-whisker-reinforced hyaluronan-gelatin scaffolds. The obtained cylindrical scaffolds obtained were about 10 mm in diameter and 2 mm in height, whereas the disc-shaped scaffolds were about 1 mm in thickness these were later cut into a desired shape and size for the mechanical property assessment. 

Other polymer-fibrous clay systems such as bionanocomposites combining gelatin and sepiolite are also efficient precursors that can be transformed into...

Gelatin is prepared by the thermal denaturation of collagen, isolated from animal and fish skin and bones, with very dilute acid. Gelatin has also been successfully and largely used as a matrix to produce bionanocomposites which are reinforced with nanoreinforcements such as clays and hydroxyapatite to be used in applications ranging from packaging materials to artificial bones. 

For several years, hydroxyapatite/gelatin bionanocomposite using biomimetic coprecipitation has been pursued as a biological bone substitute because of its biocompatibility, biodegradability and its usage as a scaffold site for regeneration of new bones [221-226].
