Structural modification of poly(ε‐caprolactone) (PCL) allows the fabrication of new functional materials obtained via the PCL films/fibers stretching in ethanol by the crazing mechanism. Atomic force microscopy, X‐ray scattering, and differential scanning calorimetry are employed to study the evolution of PCL structure. It is shown that ethanol plasticizes the polymer being deformed, and the stretching of PCL films/fibers occurs with formation of a fibrillar‐porous structure in the interlamellar space. The obtained porous matrices have pore size below 50 nm and bulk porosities of 28% and 48% for fibers and films, respectively. Thermal stabilization of the PCL films’ porous structure made it possible to obtain breathable materials with a vapor permeability of 625–652 g m−2 per day. The resulting porous PCL fibers and films can be used as matrices for the incorporation of useful additives and preparation of functional nanocomposites (NCs), biodegradable surgical suture, packaging, covering, and textile vapor‐permeable materials. Hybrid NCs with antibacterial and fungicidal activities are obtained on the basis of the porous PCL matrices and functional components (5% silver, 1% brilliant green, 28% Betadine, etc.) incorporated into them.

“…Samples 1 and 2 were obtained by chemical vapor deposition with thermal decomposition of silane, whereas sample 3 was obtained by vacuum evaporation in a diffusion pumped system using an electron beam gun. The size of the coherently scattering regions near the surface was obtained by means of reflection electron diffraction (7). The geometrical film thickness was measured with a Perthen stylus tracer Model ECW-L.…”

In the case of weak absorption, the spectral reflectance of a thin film on a nonabsorbing substrate can be used to determine the spectral dependence of the absorption constant. For this purpose, a relatively simple method is described evaluating the envelopes of the interference extrema. This method as well as a Kramers-Kronig analysis were applied to epitaxial, polycrystalline, and amorphous silicon films in the energy range 0.5-5.5 eV. With decreasing crystal quality, changes in the spectral dependence of the optical constants of these films are observed. This can be understood in terms of a decreasing long range order. * Electrochemical Society Active Member.
