“…The Altered Phase Theory of the PCNs was developed [28] that described that molecular interactions result in causing a ripple effect with influence on long range order of polymers and thus impact mechanical properties of PCNs. Based on the proposed model efforts were made to use nanoclays in design of biomaterials for bone regeneration [29][30][31][32][33]. We have used unique mineralization routes to mineralize hydroxyapatite inside nanoclays galleries for use in nanocomposites for bone tissue engineering [32,33].…”

“…Wet precipitation is often used method for preparation HAp modified clay mineral: Ambre et al, [63] prepared composite which consists of hydroxyapatite, modified clay mineral and chitosan/polygalacturonic. Apatite was formed in situ in the modified clay where hydroxyapatite in the clay exhibits differences in its lattice structure as compared to the ex situ hydroxyapatite.…”

“…Nanomechanical properties are improved not only by addition of MMT but also by HAp. Deen et al,[63] prepared monolayer film of chitosan/hydroxyapatite/halloysite by Electrophoretic Deposition (EPD). EPD was used for deposition of halloysite nanotubes and fabrication of composite chitosan-HNT and chitosan-HNT-hydroxyapatite films.…”

Polymer-ceramic nanocomposites are hybrid organo-inorganic materials. The filler phase is required at nanometer level, it means that at least one dimension of the filler phase is less than 100 nm. Boosted research interest in field of the nanocomposites is observed last decade [1][2][3][4] because of remarkable improvement of various nanocomposite properties adding low volume fractions of fillers [3]. The virgin polymer exhibits poor mechanical properties such as low strength and modulus. Introducing a small amount of ceramic particles into the polymer matrix, we can observe improvement of the properties of polymer [4]. One of the most common filler for polymers, especially for medical uses is hydroxyapatite, which is the most common apatitic calcium phosphate ceramic. The most important calcium phosphates are hydroxyapatite, tricalcium phosphate and dicalcium phosphate. Hydroxyapatite (HAp), Ca 10(PO4)6(OH)2, is a major component of hard tissues. HAp is very cheap material, which has wide utilization in medical field and also in industry. Synthetic HAp finds many applications mainly in bioceramic [5][6][7][8].Clay minerals are natural materials from phyllosilicate family. They are hydrous aluminium, iron and magnesium silicates with layered structure. Clays have characteristic layered structure contains aluminia octahedral layer and two silica tetrahedral sheets [9]. Polymer/HAp nanocomposite is widely studied materials in recent years. The main advantage is their utilization in medicine, due to improved mechanical properties and also biocompatible properties [10]. The aim of this mini review is to summarize the preparation of polymer/HAp nanocomposites, the influence of HAp filler on mechanical properties of nanocomposite and also the dispersion of hydroxypapatite in polymeric matrix. Polymer/clay mineral composites are widely used in recent years, and also the exploration of this topic is significant. It was many times proven that addition of small amount of clay mineral in to the polymer matrix improves the mechanical properties of polymer [11][12][13].Combination of polymer, hydroxyapatite and clay mineral leads to the composite with unique properties and wide range of application, especially in the medicine, since the non-living, inorganic chemical make-up of our teeth and bones is primarily composed of hydroxyapatite (Figure1).In this review the main aspects of apatitic calcium phosphates are presented. Focus is here on basic preparation techniques and their limitation, properties of prepared nanocomposites and draft-possibilities of application.
