“…[18] Therapeutic embolization entails deliberately blocking a blood vessel (e.g., clipping an aneurysm to prevent internal bleeding, or reducing/stopping blood flow to tumors), and body temperature-responsive poly(ether urethane) SMP-based foams have been shown to be cytocompatible and enable the infiltration of mouse L929 fibroblast cells in vitro which is promising for potential future applications as aneurysm fillers in vivo. [19] Different temperature-responsive polyurethane SMPs that responded to temperature by expanding up to 70 times their original volume were shown to be relatively non-immunogenic in vitro [20] and after 90 days of implantation of radio-opaque analogues in a pig aneurysm model these materials showed low inflammation and good healing responses.…”

Shape-memory polymers (SMPs) are morphologically responsive materials with potential for a variety of biomedical applications, particularly as devices for minimally invasive surgery and the delivery of therapeutics and cells for tissue engineering. A brief introduction to SMPs is followed by a discussion of the current progress toward the development of SMP-based biomaterials for clinically relevant biomedical applications.

“…However, the DSC curve for the DHC having content of 2 and 10 wt% diatomite showed a sharp endothermic peak at 124.80 ºC (T m1 ) and 121.31 ºC (T m2 ) followed by a small endothermic peak at 135.86 ºC (T m ) and 126.55 ºC (T m ), respectively. Two different endothermic melting temperature may be suggested because of recrystallization [32].…”

H eavy metal pollution is a serious environmental problem and it threats human health and ecosystem due to toxic and carcinogenic effects even at low concentrations. Many methods have been employed for the removal of heavy metals from water such as chemical precipitation, ion change, membrane separation and adsorption. Among the methods, adsorption is regarded as the most reliable choice due to technically and economically applicability [1][2][3][4].The hydrogels having three-dimensional networks of polymer chains have attracted great interests due to their high absorb, swell and water uptake capacities [5][6][7][8]. Many polymers such as polyacrylic acid (PAAc), poly (2-hydroxyethyl methacrylate, PHEMA), polyvinyl alcohol (PVA) are used in the synthesis of hydrogels. The hydrogels based on PHEMA and PAAc have been

“…2 Furthermore, synthesis of this planar, honeycomb-shaped material can be pursued in many different ways, that is, modified Hummers’ method like in our case. 3 Those carbon-based nanofillers can be applied in ecological modified polyurethane (PU) nanocoatings, 4 biodegradable containers or in medical supplies such as hydrogels, 5 tissue engineering, 6 or bionanofiber scaffolds 7 which incorporate also polycaprolactone (PCL).…”

Composites with differently shaped micro- and nanofillers show various, unique thermal, and physicochemical properties when mixed with carefully chosen polymer matrix. Selected composition holds strategic value in achieving desired properties that is biodegradability, thermoelectric conductivity, and shape memory for organic coating. The main aim of this work is to briefly examine structural changes after reaching percolation threshold and activating healing abilities within exploited (8–2 wt ratio) polyurethane–polycaprolactone thin films mixed up with different types of metallic and ferromagnetic microfillers. They, with applicable dosages of reduced graphene oxide nanoparticles, should enhance materials’ mechanical and conductive properties. Microscopic and spectroscopic techniques accompanied by extensive thermal analysis have been chosen to provide useful information about local changes in surface structure and morphology. Moreover, pristine, percolating surface with inner-formed, metallic structures shows moderate conducting properties within exploited materials which unfortunately diminish after thermal healing stimulus is being applied. This statement is supported by observing the coverage of regional defects and nearby pores with a concise, uniform layer of blend having different PU:PCL ratio. Including the additional fact that apparent filler migration is changing local dopant composition brings up an assumption that both phenomena have negative synergy effect on each other.
