In order to search nanofiller for controlling release of drugs lamellar α-zirconium phosphate (α-ZrP) was modified with ether-amine oligomer (E-A). Synthesis and chemical modification followed specific reaction conditions and different EA:ZrP ratios. Infrared spectra showed strong interaction between P-OH and NH 2 groups. Thermogravimetric curves showed that ether-amine oligomer was incorporated by ZrP. Interlamellar space of α-ZrP increased at least four times indicating intercalation. The relaxometry analysis indicated that α-ZrP molecular mobility changed according to the etheramine amount. The scanning electron microscopy/energy dispersive analysis revealed the presence of octadecylamine inside the α-ZrP galleries. The results showed that P-OH group (Brønsted acid) and amine group (Brønsted base) reacted to each other, resulting in an ionic bond PO-+ 3 HN-[-(CH 2-CH 2-O) m-(CH 2-C-H(CH 3)-O) n-]. Partially intercalated nanofiller were achieved.

“…Zirconium phosphate (ZrP) is an inorganic compound that presents interest due to its specific properties: biocompatibility [55,56], thermal stability, ion-exchange ability [57]. These characteristics make possible the utilization of ZrP in catalysis [58], drug-delivery [56], photochemistry [59], anti-corrosion protection [60]. From morphological point of view, ZrP can be found in both amorphous and crystalline form.…”

Halogen-free flame retardants for application in thermoplastics based on condensation polymers

et al. 2019

Future materials in the field of thermoplastics require a lower impact on the environment. Actual thermoplastic materials also require "greener" additives for thermal and fire resistance profile. In this work, some of the recent solutions for halogen-free flame retardants were discussed in the context of viable routes with economical and industrial relevance. The fire retardant mechanism was discussed in order to imagine new solutions for future additives. Some of the main (inorganic, organic or hybrid) flame retardants can be used as common platform for the next classes of thermoplastic composites (synthetic, natural, or bio-based). The new generation of flame retardants (based on the emerging solutions) will have to surpass two major barriers: the cost effectiveness and the need for high concentration (which usually affects other properties).

“…Therefore, it is reasonable to assume that increasing the difficulty of the diffusion pathway will effectively prevent H 2 O and O 2 from accessing the substrate surface, leading to good anticorrosion properties of the coating. Recently, many studies have shown that nanofiller can effectively enhance the barrier properties of various polymers [14,[43][44][45][46]. This is because their morphologies have high aspect ratios that lengthen the diffusion pathways for moisture or oxygen, leading to improved barrier properties [47,48].…”

In this study, a novel alumina-covered graphene oxide/polyimide (AlGO/PI) nanocomposite was developed as an anticorrosion coating material. The hydroxyl groups on GO reacted with aluminum isopropoxide via a sol-gel process to yield AlGO nanosheets. The characterization and structure were confirmed by Fourier transform infrared spectrometry, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, and field emission transmission electron microscopy. Subsequently, GO and AlGO were incorporated into a PI matrix, leading to the formation of GO/PI and AlGO/PI nanocomposites. Well-dispersed AlGO nanosheets in the PI matrix acted as effective additives to enhance the water barrier properties of GO/PI (58 g/(m 2 •day)) and AlGO/PI (43 g/(m 2 •day)) coatings. Most importantly, the resultant AlGO/PI films exhibited excellent optical transparency (>75%) and anticorrosion properties. Electrochemical measurements of corrosion potential, polarization resistance, and corrosion current as well as electrochemical impedance spectroscopy confirmed that the AlGO/PI nanocomposites exhibited better anticorrosion properties than GO/PI nanocomposites. This is likely because the insulating layer of alumina on GO can isolate the charge transfer pathway between GO and the metal substrates, leading to improved anticorrosion behavior.
