The results showed that filming medium has great affect on the structure and swelling of PU/PNIPPAm composite film and the amount of crosslinking agent influents the miscibility of PU and PNIPPAm.
However, few studies have been done about the influence of film preparation conditions on PUNIPPAm composite film structure.
In this paper, the structures of PUNIPPAm films under different filming conditions were characterized by scanning electron microscopy (SEM), and values of contact angle and water absorption on the films were determined.
The stability of the structure is balanced by hydrophobic interaction energy among polymer chains and the bending energy of the aggregated polymer filament formed in the dense region.
[12] Therefore, with the BIS amount increasing, the ESW of composite films formed in water increases, and the properties of PNIPAAm are the leading factor in film structure.

Maimaiti et al. [16] obtained coal-based CDs with sp2 carbon atoms and multilayer graphene lattice structure.
The Raman spectra (Figure 5c) were examined to further clarify the structures of the samples.
After the introduction of TPP, only slight changes occurred in the structure of CDs, and the structure became more similar to that of graphite.
These results show that the large conjugated structure of TPP facilitated electron transfer.
After the addition of TPP, the main conjugate structure of chromophore of TPP still existed.

The surface modification of cellulose fibrils (CMF) or fiber by either in-situ grafting polymerization of butyl acrylate (BA) on CMF surface via an atom transfer radical polymerization (ATRP) or adsorbing the cationic polymeric latex with core-shell structure on fiber surfaces was performed; and resulting fibers or CMF were used as reinforments in an attempt to enhance the toughness of the PP-based composites.
Moreover, polypropylene honeycomb provides an attractive alternative as structure materials.
The cationic P(BA-co-MMA/EHA-co-St) latex with core-shell structure was prepared via a two-stage seeded semi-continuous emulsion polymerizations using a cationic surfactant as an emulsifier.
This behavior is not only attributed to the hydrophobicity of CMF-PBA-40 but also is attributed to the uniform distribution of CMF-PBA in the PP matrix; the distributed CMF-PBA samples have a core-shell structure in which the thin elastic PBA shell can absorb impact energy.

In this work was investigated the catalytic potential of a new heterogeneous catalyst of stoichiometry Ca0.5K0.5TiCu0.25O3 , with double perovskite structure, in the preparation of biodiesel via ethylic route.
Introduction Currently, a large number of studies have been performed on oxides of perovskite structures in the search of new materials for technological, scientific and industrial applications [1,2].
These oxides present versatile structures able of generating a large family of solids.
The simple ABO3 perovskite structure can be described as a three-dimensional cubic network of corner-sharing BO6 octahedra, where the A-cation occupies the cavity between eight corner-sharing octahedral units.

The structures that present the optimized properties are the intercalated and the exfoliated ones.
It is known that for PEO / Na+-MMT nanohybrids intercalated structure with mono- and bi-layers of PEO can be obtained depending on the polymer content.
In all cases, intercalated structures with bilayers of polymers chains inside the galleries were obtained.

The primary structure was identified in late 80s.
