Generalized two-dimensional infrared (2D IR) correlation spectroscopy has been applied to the study of the conformational changes and specific interactions in blends of polyethylene adipate (PEA) and cholesteryl palmitate (CP). IR spectra of CP, PEA, and their blends of different compositions: 10/90, 16/84, 32/68, 64/36, and 80/20 have been recorded. In order to apply 2D IR correlation analysis, the samples are divided into two sets for 2D: set A

Fourier transform infrared (FT-IR) spectroscopy combined with 2D correlation spectroscopy has been used to offer some information about stability and structure of some soluble elastins. Temperature has been chosen as the perturbation to monitor the infrared behavior of various soluble elastins, namely, α- elastin p, α- elastin and k-elastin. In the 3800–2700 cm-1 region, the H-containing groups were analyzed. The bonded hydroxyls are found to

FT-IR and 2D correlation spectroscopy were employed to study the microstructural changes ocurring during phase transitions of a liquid crystal poly(amidoamine) codendrimer (PAMAM (L1)16(L2)16) generation 3, functionalized on the terminal groups by one-chain promesogenic calamitic units (4-(4'-decyloxybenzoyloxy)- salicylaldehyde (L1)) and two-chain promesogenic calamitic units (4-(3',4'-didecyloxybenzoyloxy)salicylaldehyde (L2)). Spectral modifications

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisation process. The paper presents the synthesis of a magnetic

Optical microscopy in ordinary and polarized light and FT-IR spectroscopy have been used to study morphology and crystalline transition of the poly(ethylene-adipate)/ cholesteryl palmitate blends. A smectic 1 to smectic 2 transition of the liquid crystalline component has been detected only in the blends, proving influence of the poly(ethylene-adipate) on the crystallization behavior of the cholesteryl palmitate.

In the paper there are presented data concerning the syntheses in cold plasma conditions of vinyl polymers. The new synthesised structures are characterized from the viewpoint of some physico-chemical properties. As a consequence of the realized structure (network) the synthesised polymers are proposed as a matrix for bioactive substances.

FT-IR spectroscopy has been employed to study compatibility, melting, and crystallization of the polyethylene adipate (PEA)/cholesteryl palmitate (CP) blends. The changes in FT-IR spectra were followed by controlled rate of heating and cooling. The bands corresponding to the crystalline structure have been assigned. The accuracy of the transition temperature determination has been improved by fitting the curve of the integral absorbance dependence
