Glycerol carbonate acrylate is a 5-membered cyclic carbonate synthesized from glycerol that is used as a chemical coupling agent and has proven highly suitable for use in the synthesis of multifunctional polyhydroxyurethanes (PHUs). The multifunctionality of the structure of PHUs is determined by the density of the carbon-amine groups generated by the Aza-Michael reaction and that of the uretha...

The aim of this study was focused on the bactericide test of Silver nanoparticles with an average diameter of 6 nm, over Escherichia coli, Staphylococcus aureus and Candida albicans and the treatment of a dermatosis of unknown etiology with a poly(hydroxy urethane-acrylate) gel (PHU) with a concentration of approximately 10 ppm AgNPs and a ratio-NHCOO-:RGD (Arg-Gly-Asp) on the macromolecular ch...

In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...

In this research, Novel UV curable conductive nanocomposites containing urethane acrylate and PANi-Co3O4 nanocomposite have been prepared. At first, PANi- Co3O4 nanocomposites have been synthesized and then PUA-PANi-Co3O4 nanocomposites films were prepared by ultraviolet radiation. UV-Vis and FT-IR studies confirm that there was strong chemical interaction between PANi and Co3O4 nanoparticles, ...

Melt electrowriting (MEW) is an additive manufacturing process that produces highly defined constructs with elements in the micrometer range. A specific configuration of MEW enables printing tubular to create small-diameter structures. The small pool processable materials poses a bottleneck for wider application biomedicine. To alleviate this obstacle, acrylate-endcapped urethane-based polymer ...
