“…Among them, polymer/clay nanocomposites, also known as organic/inorganic hybrids, raised a high interest because new multifunctional materials can be designed and they proved to be useful for a wide variety of applications [1][2][3][4][5][6]. From pharmaceutical and biomedical applications to stimuli-responsive sensors, the potential impact of nanocomposite hydrogels in everyday life is expected to progressively increase.…”

“…LDH anionic clays also known as hydrotalcite-like compounds have exhibited extensive research interest for biomedical applications, especially as drug delivery systems, due to their interesting properties in anion exchangeability, compositional flexibility and biocompatibility [1,5,23]. The basic structure of LDHs is derived from partial isomorphous substitution of divalent cations by trivalent cations in brucite-like (Mg(OH) 2 ) layers of edge-sharing MgO 6 octahedra, such that the positively charged cationic layers that result are bound together by the inter-layer counter anions as well as by water molecules.…”

“…The addition even of a small amount (around 2%) of LDH to polymer systems gives superior mechanical and thermal materials as compared with the parental components [5]. Polymer-inorganic supramolecular composites with pH sensitivity can be used for designing reversible networks through physical interactions by changing the environmental conditions, targeted and controlled drug delivery, medical health care, and many others [1].…”

Organic-inorganic hybrid pigments with enhanced thermo- and photostability have been prepared by co-intercalating C.I. Acid Red 337 (AR337) and a UV absorbent (BP-4) into the interlayer of ZnAl layered double hydroxides through a coprecipitation method. The obtained compounds were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric-differential thermogravimetric-differential thermal analysis, UV-visible spectroscopy, and the International Commission on Illumination (CIE) 1976 L*a*b* color scales. The results show the successful co-intercalation of AR337 and BP-4 into the interlayer region of layered double hydroxides (LDHs) and reveal the presence of host-guest interactions between LDH host layers and guest anions of AR337 and BP-4 and guest-guest interactions between AR337 and BP-4. The intercalation can improve the thermostability of AR337 due to the protection of LDH layers. Moreover, the co-intercalation of AR337 and BP-4 not only markedly enhances the photostability of AR337 but also significantly influences the color of the hybrid pigment.

“…Research groups around the world have explored the influence of inorganic nanoparticles on general polymer networks [19] and how the surface modification of these particles affects composite behavior [20]. However, a focused summary of the narrow but important state-of-the art in SMPINCs has remained unwritten.…”

Shape memory polymers (SMPs) have been the focus of much research over the last few decades. From the novelty of temporarily fixing a threedimensional shape from a planar polymer sheet, to the uses that SMPs are seeing today as softening biomedical implants and self-deploying hinges, this class of smart materials has successfully been used to tackle a variety of biological, electrical, and mechanical problems. However, the properties of these networks are limited by the organic nature of the SMPs. To enhance their properties, researchers across the globe have looked into imparting the desirable properties of inorganic composite materials to these polymer networks. As the field of shape memory polymer composites began to grow, researchers quantified the unique enhancements that came at varying filler loading levels as a result of controlled material interface interactions. Specifically, the incorporation of nanofillers of various shapes and sizes leads to increased internal interfacial area relative to micro-and macrocomposites at identical loading fractions and imparts interesting mechanical, optical, electrical, thermal, and magnetic properties to these emerging nanocomposites. This new class of material, referred to in this review as shape memory polymer-inorganic nanocomposites (SMPINCs), allows a host of new interactions between the smart polymer and its surrounding environment as a result of the ability to control the internal environment of the polymer network and nanofiller. In this work, the reader is introduced to both the methods of preparing these composites and the effects the fillers have on the biological, electromagnetic, and mechanical properties of the resulting composite.
