Cancer is one of the most serious public health problems that affect humanity. Diverse delivery systems of anticancer drugs have been developed to enhance the treatment effectiveness and patient compliance. Thus, drug delivery systems from polymeric films could be an interesting and promising alternative, especially for skin chemotherapeutics. In t...

AbstractNew high efficiency luminescence films that convert UV radiation in a wavelength range of 220–410 nm into the europium ion luminescence are first obtained using a supramolecular diamond-containing complex of europium(III) with bathophenanthroline. The films allow the degree of radiation monochromaticity to be tuned at the main band of Eu3+ ...

AbstractThe ratios between the film-sorbent parameters, sensitivity, and quartz sorption sensors’ sensitivity threshold have been obtained and analyzed. It has been demonstrated that, for the sorption sensors of vapors and gases based on polymer films, there exists a range of optimal values of thickness caused by its effect on the elastic propertie...

AbstractVarious poly(lactic-co-glycolic acid)-based polymeric films with various molecular weights were obtained. The mechanical characteristics of these films were investigated. It was shown that the obtained polymer films do not have a short-term toxic effect on mammalian cells. The percentage of actively dividing cells on such polymer films is 1...

AbstractA technique for measuring the internal stresses in polymer films deposited on a glass substrate in gas discharge plasma is developed. Using this technique, the dependence of internal stress in thin films of polymethylmethacrylate and polystyrene on the deposition time and the current density of the barrier discharge at atmospheric pressure ...

AbstractThe kinetics of water vapor permeability of insulating tapes of the Polyen, Poliken, Nitto, and Furukawa series was studied by the gravimetric method in the temperature range from 20 to 70°С. It is shown that for all the investigated tapes, in spite of their two-layer construction, normal Fikov kinetics of permeability is observed. Diffusio...

Most film coatings in the pharmaceutical industry are prepared using organic solvents or aqueous solvents. Due to different film-formation mechanisms, their properties are significantly different from each other. Curing can alter the microstructure of films by improving the coalescence of polymer particles for aqueous dispersion-based films or acce...

Rheological properties and diffusion permeability of butadiene–styrene film in vapors of organic solvents were studied in both the equilibrium and nonequilibrium states. The investigations by quartz acoustic gravimetry showed that, under the influence of butadiene, acetone, ethanol, dimethylformamide and water vapors, the shear modulus and mechanic...

Soft robots, sensors, and energy harvesters require materials that are capable of converting external stimuli to visible deformations, especially when shape-programmable deformations are desired. Herein, we develop a polymer film that can reversibly respond to humidity, heating, and acetone vapors with the generation of shape-programmable large def...
