2.2 Rectorite (1:1) Clay-Reinforced Polymer Nanocomposites. Rectorite clay contains an alternative arrangement of nonexpansible and expansible layers in a 1:1 ratio. The nonexpansible layer is made up of dioctahedral mica, whereas the expansible layer consists of dioctahedral smectite. The rectorite clay offers the advantage of easy exchange of ...
Abstract: The chitosan/rectorite composite was prepared and characterized by XRD. The interlayer distance of rectorite was enlarged from 2.53 nm to 3.01 nm. Congo red (CR) was selected as a model anionic dye and the adsorption tests of CR onto chitosan/rectorite composite were carried out. The results showed that the CR adsorption process is ...
Constructing lightweight and porous adsorbents which can effectively remove dye contaminants is of great significance in the field of the sewage treatment. In this work, anisotropic cellulose nanofibril (CNF) composite sponges assisted by rectorites are fabricated through directional freeze-drying. …
Rectorite can be easily cleaved between smectite inter-layers to form 2 nm thick monolithic rectorite [101, 102]. The interlayer cations present in smectite layers in rectorite can be easily exchanged by organic or inorganic cations and hence rectorite can be used as an adsorbent for harmful metallic cations and cationic dyes [102].

Through the hemostatic property of rectorite, the viscous nanocomposite decreased the in vitro clotting time by 43%. Moreover, an in vitro porcine skin model confirmed that the viscous nanocomposite can stably adhere on skin and impede blood bleeding successfully. Importantly, the internal structure of the nanocomposites, chitosan intercalating ...
It was concluded, thus, that rectorite consisted of a regularly alternating sequence of paragonite-like layers and expandable layers having beidellitic and montmorillonitic compositions. It was also emphasized that, because variations in the kind and population of interlayer cations were recognized among similar materials, the specific name ...
Silicate minerals can be thought of as three-dimensional arrays of oxygen atoms that contain void spaces (i.e., crystallographic sites) where various cations can enter. Besides the tetrahedral (4-fold coordination) sites, 6-fold, 8-fold, and 12-fold sites are common. A correlation exists between the size of a cation (a positively charged ion ...
Among the layer silicate clays, rectorite (REC) is a kind of regular interstratified clay consisting of a muscovite-like layer and a montmorillonite-like layer in the ratio of 1:1 (4). Curing behavior and rheology properties of alkyl-imidazolium-treated rectorite/epoxy nanocomposites
