“…These hybrids can be used as nanofilms or nanocoatings formed in continuous (flow) regime during surface modification of various thermoplastic films, as reaction-capable compatibilizers, fillers for thermoplastic polymer compositions, especially based on acryl polymers, components of nanomaterials, made via extrusion, masterbatches, etc. [86,195,[198][199][200][201].…”

The driving force of development of intercalation chemistry is significant improvement of properties of fabricated nanocomposites and design of materials with new properties. Forming hybrid structures (sometimes called "ship-in-the-bottle") define important functional characteristics: improved mechanical strength (increase in modulus), enhanced stiffness, heat resistance (decrease in thermal expansion coefficient), heat stability, and other thermal physical properties, water resistance, interesting barrier properties for gas separation, high flame and fire resistance, electric and electrochemical behavior, size stability, chemical stability, different from the simple additive properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].Hybrid-phase nanocomposites [21] are not only of academic, but of commercial interest, because they posses improved mechanical and thermal properties as compared with the same content of conventional fillers (such as carbon soot or deposited silica gel). The methods of production of hybrid nanocomposites from polymer solutions or polymerization in situ in combination with delamination and exfoliation were already studied at the end of the last century (for example, [22,23]). However, there were technological drawbacks: these methods had low correlation with polymer production and demanded great amounts of organic solvents. At the beginning of 1990s more convenient technique appeared on the basis of PEO (polyethylene-oxide) and MMT (montmorillonite), which advantageously demonstrated the intercalation process in the polymer melt, as well as potential applications of the obtained products in solid phase electrolytes of recharged lithium batteries.However, highly promising commercial strategy in this problem was formulated after the group of researchers of Toyota company [24][25][26] had found extraordinary strengthening of mechanical properties of polymer-layered nylon-based nanocomposites, which was caused by extremely large surface contacts of the ingredients and high aspect ratio reached in the intercalation/exfoliation process, and by homogenous dispersion of silica plates in the polymer matrix [27,28]. On the one hand, these functional materials have a relation to nanocomposites via

“…Character of this interaction strongly depends on the nature and functionality of the chosen monomer and polymer chains, which may provide an effective interaction with silicate layers via complex-formation, hydrogen bonding, and amidization/imidization reactions (in the case of primary alkyl amine modified MMT [4]). Effect of H-bonding in ternary solvent/protondonor polymer/proton-acceptor polymer system was also reported by Figueruelo et al [42].…”

“…This considerable scientific and engineering interest has been stimulated by possibility of the significant improvements in physical, mechanical, thermal and other important specific properties of PLS materials. The results of these researches were summarized and discussed in several reviews and articles [1][2][3][4][5][6][7]. PLSs are a class of organic-inorganic hybrids, composed of organic polymer matrix in which layered silicate particles of nano-scale dimension are embedded because these nanocomposites show enhanced mechanical properties [8,9], gas barrier properties [10], and improved thermal stability [5,11,12], low flammability [11,12] and protection effects from corrosion [13,14].…”

“…Wang et al [36,37] showed that a comparison of solution, emulsion, suspension and bulk polymerization along the nanocomposites may also be prepared by melt in situ reactive blending of monomer/polymer/clay mixtures. Recently, we have reported the synthesis of the functional copolymer/silica (or organo-silicate) hybrids and polypropylene/organo-MMT nanocomposites by (1) reaction of anhydride-containing copolymers with γ-aminopropyltriethoxysilane [38][39][40], (2) interlamellar copolymerization of maleic anhydride with some vinyl and acrylic comonomers [40] and (3) reactive extrusion in situ processing [4,40]. In this work, we present (a) the synthesis of poly[maleic anhydride (MA)-co-nbutylmethacrylate (BMA)/organo-MMT, poly(MAalt-styrene-co-BMA)/organo-MMT, and poly[ita-conic acid (IA)-co-styrene-co-BMA)]/organo-MMT nanoarchitectures prepared by complex-radical interlamellar copolymerization, (b) the results of the copolymer composition-nanostructure formation relationship studies, and (c) characterization of (co)terpolymer/organo-MMT nanocomposites by thermal (DSC and TGA-DTG), dynamic mechanical (DMA), X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis methods.…”

Abstract. The functional copolymers, having a combination of rigid/flexible linkages and an ability of complex-formation with interlayered surface of organo-silicate, and their nanocomposites have been synthesized by interlamellar complex-radical (co)terpolymerization of intercalated monomer complexes of maleic anhydride (MA) and itaconic acid (IA) with dimethyl dodecylamine surface modified montmorillonite (organo-MMT) (MA…DMDA-MMT and IA…DMDA-MMT) n-butyl methacrylate (BMA) and/or BMA/styrene monomer mixtures. The results of nanocomposite structure-composition-property relationship studies indicate that interlamellar complex-formation between anhydride/acid units and surface alkyl amine and rigid/flexible linkage balance in polymer chains are important factors providing the effective intercalation/exfoliation of the polymer chains into the silicate galleries, the formation of nanostructural hybrids with higher thermal stability, dynamic mechanical behaviour and well dispersed morphology.

“…However, this could affect inversely the miscibility between the high-molecular weight matrix PP and the compatibilizer. Depending on a nanoscale dispersion of the layered silicate, the whole spectrum of structures, ranging from intercalated to exfoliated PP nanocomposites, have been observed by WAXD, SAX (see, for instance, Figure 4) and TEM [166,[169][170][171][172]. It is well known that functionalization with mPP could lead to chain scission of the PP, which, in turn, can drastically diminish the mechanical properties of final composite [172].…”

Polypropylene is an extremely versatile thermoplastic polymer known for its good performance/price ratio, excellent heat, moisture and chemical resistance, favorable processing characteristics and recyclability. Due to its universal properties, polypropylene is applied in numerous industrial fields such as electronic and electrical, automobile, textile, pipeline, etc. Furthermore, the progress in its synthesis and property modification in the last decade has contributed to the development of new polypropylene based materials with advanced performance. This review aims at reporting on some recent developments in polypropylene based materials, such as nanofibers, natural fiber reinforced composites, self-reinforced polypropylene and polypropylene/clay hybrids, that have replaced many types of engineering thermoplastics in high-performance applications.
