New aromatic co-polyamide-imides (coPAIs) containing both carboxyl and hydroxyl groups in the repeating units were synthesized for first time. Transport, thermal morphological properties of dense nonporous membranes from PAIs obtained using diacid chloride 2-(4-carboxyphenyl)-1,3-dioxoisoindoline-5-carboxylic acid diamines 5,5′-methylene-bis (2-aminophenol)) 3,5-Diaminobenzoic acid, taken molar ratios 7:3, 1:1, 3:7, have been studied. High levels membrane permeability accompanied by high...
The series of new thermoplastic elastomer films based on copoly(urethane-imide)s (coPUI)s and nanocomposites containing from 1 to 10 wt. % carbon nanofillers different morphology (single-walled nanotubes, nanofibers, graphene) as well WS2 WSe2 nanoparticles, were prepared investigated by atomic force microscopy in contact mode. friction coefficient (Cfr) the surfaces under conditions true slip was determined both one scan field with multiple scans (200-400) place. measurements carried out at...
Two sets of hybrid polyurethane–poly(2-hydroxyethyl methacrylate) semi-interpenetrating polymer network–nanooxide composites with 0.25 or 3 wt% nanosilica nanoalumina functionalised OH, NH2 CHCH2 groups were prepared. A combination atomic force microscopy, infrared spectroscopy, thermally stimulated depolarisation current measurement, differential scanning calorimetry and creep rate spectroscopy analysis the nanostructure properties was performed. The pronounced dynamic heterogeneity strong...
Abstract Nanostructure, glass transition dynamics and elastic properties were studied in the 3D nanodiamond‐containing composites based on polyurethane‐poly(2‐hydroxyethyl methacrylate) semi‐interpenetrating polymer networks (PU‐PHEMA semi‐IPNs), neat PU or PHEMA matrices. Nanodiamond (ND) content nanocomposites varied from 0.25 to 3 wt %. Combined differential scanning calorimetry/ laser‐interferometric creep rate spectroscopy/atomic force microscopy approach was utilized. A large impact of...
A combined wide angle X‐ray diffraction (WAXD)/small‐angle scattering (SAXS)/scanning electron microscopy (SEM)/density study of structure and morphology was carried out for a large series pyromellitic dianhydride‐oxydianiline (PMDA‐ODA) polyimide (PI) samples processed using different powder metallurgy techniques. Using DSC/creep rate spectroscopy (CRS)/long‐term creep resistance (LTCR) approach, their molecular dynamics, thermal elastic properties, in the temperature range from 20 to 470°C...
Polyurethane-poly(2-hydroxyethyl methacrylate) semi-IPN-silica nanocomposites with low content (0.25 and 3 wt%) of differently functionalized 3-D fumed silica nanoparticles were studied using a combined AFM/DSC/CRS approach over the −100 to 160°C range. The pronounced heterogeneity PHEMA PU glass transitions’ dynamics effects considerable suppression increasing elastic properties by additives shown. It was caused formation peculiarly cross-linked structures due “double hybridization,” in...
The main objective of this study was to allocate and evaluate the most optimum conditions prepare 5-Fluorouracil (5-FU) entrapped polycaprolactone (PCL) nanoparticles (5-FU–PCNs) by eco-friendly route. inner aqueous phase (W1) added solution containing PCL with homogenization form primary emulsion (W1/O) which emulsified outer (W2) polyvinyl alcohol (PVA) as stabilizer attain double (W1/O/W2). different parameters were investigated reach successful formulation for 5-FU–PCNs, such polymer...
Abstract Comparative WAXD/SAXS/SEM/DSC structural studies of a series semi‐crystalline poly(oxymethylene) (POM) engineering plastics, including the commercial products, homopolymer Delrin ® and typical poly(oxymethylene‐ co ‐oxyethylene)s, few lab‐made POM compositions, were performed. The latter differed in their content functional additives (present low concentrations) molecular weight characteristics. In parallel, densities, thermal behavior/laser‐interferometric creep rate spectra...
Composite systems containing electroconducting polymer coatings (polyaniline and polypyrrole) applied to porous films of semicrystalline polymers (polyethylene, polypropylene, polyvinylidene fluoride) have been prepared. Porous supports were obtained in the process based on melt extrusion with subsequent annealing, uniaxial extensions, thermal stabilization. Conducting formed by oxidative polymerization monomers directly onto supports. The structure (overall porosity, permeability, pore...
