“…HA was prepared by using cationic surfactant CTAB as a template with a ratio of n (CTAB)/ n (HA) of 1:2 and concentrations of Ca(NO 3 ) 2 solution and (NH 4 ) 2 HPO 4 solution of 0.5 mol L −1 and 0.3 mol L −1 , respectively. In the process of preparation, the ratio of n (Ca)/ N (P) was 5:3 . The detailed steps are as follows.…”

In this study, the self‐made nano‐hydroxyapatite (HA) and poly(butylene adipate‐co‐butylene terephthalate) copolyesters (PBAT) were used as fillers, and composite films of HA/PLA (PLA, polylactide) and HA/PBAT/PLA systems were prepared. The micromorphology, mechanical properties, thermal properties, crystallinity, water vapor permeability and oxygen permeability of the composite films were studied. The results show that the self‐made HA has a porous rod‐like structure with a size of 30–50 nm. PBAT was dispersed uniformly in the HA/PLA matrix in the form of spherical particles and formed many pores and holes. The tensile strength, elongation at break and modulus of elasticity of HA/PLA composite films were increased by adding 10 wt% PBAT. The addition of HA and PBAT played a synergistic function in improving the crystallinity of the composite films. The water vapor and oxygen permeabilities of HA/PLA and HA/10%PBAT/PLA composite films can be regulated by adjusting the amount of HA. The results of this study indicate that composite films with higher water vapor and oxygen permeabilities exhibit great potential for applications in green packaging and fresh‐keeping packaging. © 2019 Society of Chemical Industry

“…At a calcination temperature higher than 650°C, the wall of the pores is destroyed, negatively affecting on meso‐macroporous structure of the sample. Therefore, with respect to the calcination temperature and time used in this study, it is expected that some surfactants remain in the film (Liu, Yang, & Troczynski, ; Uota et al, ; Wang, S‐p, Hu, K‐c, & Sun, ).…”

Meso-macroporous nanohydroxyapatite coatings (MHACs) were synthesized on Ti6Al4V implant materials calcined at different temperatures using a nonionic diblock copolymer template (C 12 E 10 ) by sol-gel and dip-coating methods. To improve the bonding strength between the substrate and coating, a TiO 2 intermediate layer was applied on the surface of the substrates. The physicochemical and structural properties of MHAC samples were fully studied by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, scanning probe microscopy, field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller method, and contact angle measurements. Based on the data obtained, the hydroxyapatite phase with a flower-like morphology was formed on the Ti6Al4V substrates in all of the samples. According to confocal optical microscopy and FESEM images, there was no macrocrack and microcrack on the MHACs, whereas they were accompanied by macroporosities and mesoporosities on top of the coatings. By increasing the calcination temperature from 500 C to 650 C, the crystallite sizes increased, while the surface roughness value and hydrophilicity decreased. A reduction in specific surface area and an increase in the pore diameters occurred as the calcination temperature increased. In addition, the assessment of protein adsorption behavior over the samples revealed that the adsorption amounts significantly increased as the substrates were coated with HAP; however, the affinity of surface for protein adsorption was strictly dependent on the surface topography and hydrophilicity. in vitro cellular assay disclosed a great cytocompatibility in terms of adhesion and proliferation in MHAC samples as compared with that in TiO 2 -coated and bare substrates. Regarding the physicochemical properties and biological studies, MHAC calcined at 650 C was deemed optimal for bone tissue engineering.

The objective of the present work is to prepare and characterize a porous material using quite particular and localized dunar sand (erg) of the desert near the El-Oued (south-east of Algeria). The porous material is prepared according to the mechanism of co-operative self-assembly. The method consists of polymerizing a silicic precursor (sodium silicate obtained by alkali fusion of sand with the sodium carbonate) around micelles of surfactant in an acid aqueous solution according to the sol-gel process. The elimination of the surfactant by calcining at high temperature leads to the final material which was characterized by XRF, XRD, MEB-EDX, FTIR and BET techniques.
