“…But, when three-dimensional frameworks such as zeolites or mesoporous silicates, are used as inorganic components and polymer is formed without crosslinking, the polymer chains could be partially or completely removed from the product. In this case, the composite is called pseudo-interpenetrating polymer network (PIPN) [ 136 , 137 ].…”

Over the past decades, organic-inorganic hybrid polymers have been applied in different fields, including the adsorption of pollutants from wastewater and solid-state separations. In this review, firstly, these compounds are classified. These compounds are prepared by sol-gel method, self-assembly process (mesopores), assembling of nanobuilding blocks (e.g., layered or core-shell compounds) and as interpenetrating networks and hierarchically structures. Lastly, the adsorption characteristics of heavy metals of these materials, including different kinds of functional groups, selectivity of them for heavy metals, effect of pH and synthesis conditions on adsorption capacity, are studied.

“…[74][75][76] Poly(ethyl acrylate). Subsequently, Frisch et al [77][78][79] were also able to form both PIPNs and IPNs from poly-(ethylene acrylate) (PEA) and zeolite 13 X. In this case, the polymerization was carried out at 40 °C using (liquid) ethyl acrylate monomer in the zeolite mixtures, with benzoyl peroxide initiator, in either the absence or presence of EGDM crosslinker.…”

The purpose of this brief review is to describe some recent, preliminary attempts to prepare nanocomposites in which polymer chains thread through the cavities or channels of several types of inorganic materials, specifically zeolites, a mesoporous hexagonal form of silica, and silica nanotubes. One goal is to determine the effects of the constraining geometry on the properties of the chains, in particular, their glass transition temperatures. Another is the hope that this molecular threading will provide such intimate interactions between the polymer chains and their inorganic environment that novel reinforcement effects will be obtained.

“…The other report is that zeolite bring on reinforcing effects on the polymer, such as mechanical properties and crystallization behavior, because polymer chains could pass through zeolite pores in the nanocomposites. In particular, Frisch et al [10][11][12] prepared interpenetrating polymer network (IPN) of zeolite 13X and polystyrene or polyethylacrylate, which prepared by using in-situ radical polymerization. In addition, Bein and Wu reported about preparation of molecular wires and conducting polyaniline filaments from polymer chains constrained into zeolite pores.…”

The crystallization behavior and fine structure of poly(ethylene terephthalate) (PET)/A-zeolite nanocomposites were assessed via differential scanning calorimetry (DSC) and time-resolved small-angle X-ray scattering (TR-SAXS). The Avrami exponent increased from 3.5 to approximately 4.5 with increasing A-zeolite contents, thereby indicating a change in crystal growth formation. The rate constant, k, evidenced an increasing trend with increases in A-zeolite contents. The SAXS data revealed morphological changes occurring during isothermal crystallization. As the zeolite content increased, the long period and amorphous region size also increased. It has been suggested that, since PET molecules passed through the zeolite pores, some of them are rejected into the amorphous region, thereby resulting in increased amorphous region size and increased long period, respectively. In addition, as PET chains piercing into A-zeolite pores cannot precipitate perfect crystal folding, imperfect crystals begin to melt at an earlier temperature, as was revealed by the SAXS profiles obtained during heating. However, the spherulite size was reduced with increasing nanofiller content, because impingement between adjacent spherulites in the nanocomposite occurs earlier than that of homo PET, due to the increase in nucleating sites.
