Polyoxymethylene‐homopolymer/hydroxyapatite nanocomposites for biomedical applications

Abstract: In this article, new polyoxymethylene (POM)/hydroxyapatite (HAp) nanocomposites for bone long-term implants have been obtained and characterized by using FTIR, WAXD, SEM, TG, DSC, tensile tests, and in vitro evaluation. Characteristic bands both for extended chain crystals (ECC) and folded chain crystals (FCC) were observed in FTIR profiles for both pure POM and POM in POM/HAp nanocomposites. From WAXD analysis it has been found that the addition of HAp does not change the hexagonal system of POM in POM/HAp na… Show more

“…while for POM HAp nanocomposites the highest degree of crystallinity was determined for T2H5, next one was for UH5, and the lowest one was for DH5 (52.94%, 46.98%, and 41.18%, resp.) [15][16][17]. The same trend was observed for the hardness results that confirm our previous results.…”

“…The same trend was observed for the hardness results that confirm our previous results. Different hardness values ( Figure 6) can be probably attributed to crystalline and amorphous regions as shown in SEM microphotographs [15][16][17]. This dependence was well documented in the literature for different macromolecular systems, and, generally, microhardness increases with increasing degree of crystallinity of polymer [33].…”
