Abstract Hydroxyapatite/poly‐ L ‐lactide (HAp/PLLA) is a ceramic/polymer composite, whose application as resorbable biomaterial for the substitution and repair of hard bone tissue widely promising in orthopedic, oral, maxillofacial, reconstructive surgery. Hot processing necessary step obtaining HAp/PLLA composite blocks with mechanical properties similar to those bones. In this article, changes structure physicochemical hot pressed different pressing times (5, 15, 30, 45, 60 min), were...

Abstract Thermal decomposition of PEO under vacuum was used in combination with a glow discharge to deposit PEO‐like plasma polymer films. Evaporation without allows the deposition films chemical composition very close that original PEO, albeit lower average molar mass. The application during evaporation leads enhancement crosslinking within films, yet at expense reduced retention ether structure. Non‐fouling properties and thrombogenicity polymers were studied terms adhesion blood proteins...

We investigated the effect of two ionic surfactants on composition and structure hydrogels obtained by swelling an epoxy amphiphilic polymer network (APN) using a combination gravimetry small-angle neutron scattering (SANS). Stoichiometric APN was synthesized reaction diamino diepoxy-terminated polypropylene (POP) polyoxyethylene (POE). Sub- supercritical solutions with either cationic (myristyltrimethylammonium bromide (C14TAB)) or anionic (sodium dodecyl sulfate (SDS)) headgroups in heavy...

The microstructure of compression molded Estane 5703 films exposed to 11%, 45%, and 80% relative humidity 70 °C for 1 2 months has been studied by small-angle neutron scattering (SANS), Fourier transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), differential scanning calorimetry (DSC). Scattering data indicated increase the interdomain distance domain size with a higher longer aging time. GPC showed progressive shortening polyurethane chains increasing caused drop...

Since the time of Faraday's experiments, optical response plasmonic nanofluids has been tailored by shape, size, concentration, and material nanoparticles (NPs), or mixing different types NPs. To date, water-based liquids have most extensively investigated host media, while polymers, such as poly(ethylene glycol) (PEG), frequently added to introduce repulsive steric interactions protect NPs from agglomeration. Here, we an inverse system non-aqueous nanofluids, in which Ag Cu are dispersed...

Immiscible polymer blends tend to undergo phase separation with the formation of nanoscale architecture which can be used in a variety applications. Different wet-chemistry techniques already exist fix resultant polymeric structure predictable manner. In this work, an all-dry and plasma-based strategy is proposed fabricate thin films microphase-separated polyolefin/polyether blends. This achieved by directing (−CH2−)100 (−CH2–CH2–O−)25 oligomer fluxes produced vacuum thermal decomposition...
