“…The addition of SrHAp nanorods seems to decrease gradually the contact angle of nanocomposites, indicating that the materials becomes more hydrophilic. This observation is in good agreement with previous work on PBSu composites, where the addition of poly(l-lactic acid) (PLLA)-grafted TTCP particles (g-TTCP) in the PBSu effectively improved its hydrophobic property [29]. PBSu/ SrHAp nanocomposites with 0.5, 1 and 2.5 wt% nanorods have contact angles 74±1, 72.9±0.50 and 70.3±0.2° respectively.…”

“…Similar reactions were mentioned in PBSu/silica nanocomposites and it was revealed that silanol groups (Si-OH) in SiO 2 nanoparticles could react with the hydroxyl end groups of the polyesters. Such a reaction was verified using results from solid-state 29 Si NMR and FTIR spectra of PBSu/silica nanocomposites, indicating covalent bonding between SiO 2 particles and the PBSu macromolecular chain [13][14][15]. In the present study FTIR and XPS were used to examine the possibility of such reactions to take place between Sr-OH groups of SrHAp nanorods and PBSu.…”

“…PCL was blended with various other biodegradable polymers in a number of studies [12][13][14][15][16][17][18][19][20][21][22]. Amongst various biodegradable polymers, PBS was the most interesting aliphatic polyester due to its relatively good melt processability, thermal and chemical resistance, biodegradability, and excellent mechanical properties, closely comparable to those of the widely-used polyethylene (PE) and polypropylene (PP) [4,5,[15][16][17][18][19][20][21][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Double crystalline PCL/PBS blends are particularly interesting because each component has an influence on the crystallization behaviour of the other component.…”

Abstract. Biodegradable polymers received considerable attention due to their contribution in the reduction of environmental concerns and the realization that global petroleum resources are finite. The development of double crystalline biobased blends such as poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) are particularly interesting because each component has an influence on the crystallization behaviour of the other component, and thus influences the strength and mechanical properties of a polymer blend. The lack of miscibility between PCL and PBS constitutes a bottleneck, and efforts have been made to improve the miscibility through the inclusion of copolymers. Having realized that incorporating conductive nanofillers such as carbon nanotubes (CNTs), (especially when the CNTs are functionalized or used as a masterbatch i.e., polycarbonate/MWCNTs masterbatch), into biopolymer matrices, can enhance the thermal and mechanical properties, as well as electrical and thermal conductivity, a lot of research was aimed at the production of bionanocomposites. This review paper discusses the properties of PCL, PBS, their blends, and their CNTs containing nanocomposites.

In this study, L-lactide was used to modify the tricalcium phosphate (β-TCP) and tetracalcium phosphate (TTCP) surface which can form functionalized poly(l-lactic acid) (PLLA)-grafted β-TCP (g-β-TCP) and PLLA-grafted TTCP (g-TTCP) particles. The g-β-TCP and g-TTCP obtained were incorporated into a PEG-PCL-PEG (PECE) matrix to prepare injectable thermosensitive hydrogel composites. The morphology of the hydrogel composites showed that the g-β-TCP and g-TTCP particles dispersed homogeneously into the polymer matrix, and each hydrogel composite had a three-dimensional network structure. Rheologic analysis showed that the composite had good thermosensitivity. Changes in calcium concentration and pH in simulated body fluid solutions confirmed the feasibility of surface-functionalized calcium phosphate for controlled release of calcium. All the results indicate that g-β-TCP/PECE and g-TTCP/PECE hydrogels might be a promising protocol for tissue engineering.
