The curing agent content plays an important role in the synthesis of polymer composites, as it determines the quality and durability of these materials. Cyanethyl-diethylenetriamine (CEDETA) was used as the curing agent for epoxy epikote 828. The effect of CEDETA content on the gel content and fracture toughness (KIC) of epoxy resin, as well as the effect of reinforcing fabric on the mechanical properties of composite materials was studied.

This article reports initial results of fabricating a tailor-made 3D dosimeter using radiochromic material and a 3D printer. The 3D dose distribution is easily visualized and quantitated as the transparent polymers become colored after irradiation. With this technology, we propose a novel method that uses 3D dosimetry to precisely copy the shape of human organs with our 3D printed dosimeter and help provide more accurate and safe radiotherapy.

Wool has disulphide bonds containing-hydrophobic external keratin layers, which act as a barrier for the modification through coating with hydrophilic materials. For that reason, in this work, to ensure a dense and homogenous conductive polymer coating onto the wool, the fabrics were subjected to the reduction process in the aqueous alkaline medium containing agents that can attack these disulphide bonds. Then, one of the polyaniline derivatives, poly(mtoluidine) (PMT), was coated onto wool by in situ polymerization of m-toluidine sulphate using ammonium persulfate (APS) as an oxidant.

The life-time or service working life of a polymer material is the continuous service period of the material from the time it is affected by usage conditions or environment until its decomposition or degradation according to some failure criterion. The accuracy of predicting the life-time of a polymer material depends on a forecasting equation that fully reflects climatic factors, weather, environment, usage conditions, etc. affecting the material as well as the selected failure criterion.
