“…These results are in agreement with previous studies [2,6,11,21]. The thermal transition of blend was those typical of the pure polymers with two Tg at 105.9 and 130.5°C.…”

“…The drawbacks of the blend are the immiscibility of PVA and collagen solutions except for a very low concentration of PVA in which they interact by hydrogen bonds, and their poor mechanical properties [11]. A further improvement in the characteristics of such materials could reasonably be expected if interaction that stronger than hydrogen bonds occurred between collagen and PVA [6].…”

“…Previous study of collagen and PVA blend [10][11][12] showed that the collagen/PVA blends also display good film-forming properties which are a favorable characteristic for application in biomedical field. The drawbacks of the blend are the immiscibility of PVA and collagen solutions except for a very low concentration of PVA in which they interact by hydrogen bonds, and their poor mechanical properties [11].…”

“…PVA is a hydrophilic synthetic polymer that possesses excellent recognised biocompatibility and properties such as non-toxicity, non-carcinogenicity, ease of processing and mechanical strength [11][12][13][14]. It has been studied as bone substitute material or bone scaffold coating when mixed with ceramics [14][15][16], a synthetic articular cartilage [17][18][19], artificial pancreas [20], artificial skins [21,22], and drug delivery systems [23], etc.…”

Porous poly(vinyl alcohol) (PVA)/sepiolite nanocomposite scaffolds containing 0-10wt.% sepiolite were prepared by freeze-drying and thermally crosslinked with poly(arylic acid).The microstructure of the obtained scaffolds was characterised by scanning electron microscopy and micro computer tomography, which showed a ribbon and ladder like interconnected structure. The incorporation of sepiolite increased the mean pore size and porosity of the PVA scaffold as well as the degree of anisotropy due to its fibrous structure.The tensile strength, modulus and energy at break of the PVA solid material that constructed the scaffold were found to improve with additions of sepiolite by up to 104%, 331% and 22% for 6wt.% clay. Such enhancements were attributed to the strong interactions between the PVA and sepiolite, the good dispersion of sepiolite nanofibres in the matrix and the intrinsic properties of the nanofibres. However, the tensile properties of the PVA scaffold deteriorated in the presence of sepiolite because of the higher porosity, pore size and degree of anisotropy.The PVA/sepiolite nanocomposite scaffold containing 6wt.% sepiolite was characterized by an interconnected structure, a porosity of 89.5% and a mean pore size of 79μm and exhibited a tensile strength of 0.44MPa and modulus of 14.9MPa, which demonstrates potential for this type of materials to be further developed as bone scaffolds.
