“…PBSu/SrHAp nrds 2.5 wt% shows the fastest enzymatic degradation among the tested samples, losing 14% of its initial after 40 days of enzymatic hydrolysis. These results are in accordance with our previous study on PBSu/SrHAp nanorods and PBSu/SiO 2 nanotubes nanocomposites prepared by the melt mixing technique, where the nanocomposites reported that have higher hydrolysis rates that of neat PBSu [9]. Li et al [25] found that PLA/SiO 2 nanocomposites degrade faster than neat PLA, indicating that incorporation of silica enhances biodegradation of PLA in nanocomposites too.…”

“…The crystalline structure of the nanocomposites was studied using XRD. The crystal unit cell of PBSu is monoclinic and diffraction peaks from [020] and [110] are observed at 2& 19.8 and 22.6° respectively [9,11,20]. Although SrHAp nanorods are crystalline materials none of their peaks can be recognized, even these with high intensity at 20.4, 26.6 and 31°, because they are overlapped by denser PBSu peaks ( Figure 5).…”

“…This was the main problem in our previous study in which PBSu/SrHAp nrds nanocomposites have been prepared by melt mixing using 5 and 20 wt% SrHAp nrds [9]. It is well known that the filler dispersion inside the polymer matrix affects the mechanical properties of the materials.…”

“…Therefore, optimal performance is achieved when the small particles are uniformly dispersed throughout the polymer and interact strongly with the organic matrix. Recently, PBSu nanocomposites containing SiO 2 nanotubes and SrHAp nanorods at relatively high concentrations 5 and 20 wt% were prepared by melt mixing and studied as potential materials for tissue engineering applications [9]. Concerning of Sr-substituted hydroxyapatite SrHAp nrds could stimulate osteoblasts proliferation in vitro and provide an ideal environment for colonization, proliferation, and differentiation of osteoblasts to form new bone in vivo, due to its numerous phosphate groups, which could have a positive effect on cell growth.…”

Novel poly(butylene succinate) (PBSu) nanocomposites containing 5 and 20 wt% mesoporous strontium hydroxyapatite nanorods (SrHNRs) and silica nanotubes (SiNTs) were prepared by melt-mixing. A systematic investigation of the thermal stability and decomposition kinetics of PBSu was performed using pyrolysis-gas chromatography-mass spectroscopy (Py-GC-MS) and thermogravimetry (TG). Thorough studies of evolving decomposition compounds along with the isoconversional and model-fitting analysis of mass loss data led to the proposal of a decomposition mechanism for PBSu. Moreover, the effects of SrHNRs and SiNTs on the thermal stability and decomposition kinetics of PBSu were also examined in detail. The complementary use of these techniques revealed that the incorporation of SiNTs in PBSu does not induce significant effects neither on its thermal stability nor on its decomposition mechanism. In contrast, the addition of SrHNRs resulted in the catalysis of the initial decomposition steps of PBSu and also in modified decomposition mechanisms and activation energies. The evolving gaseous products of PBSu and their evolution pattern in the SiNT nanocomposites were the same as in neat PBSu, while they were slightly modified for the SrHNR nanocomposites, confirming the findings from thermogravimetric analysis.
