The macroinitiator with two chain-growing centers per molecule is based on hydroxyl terminated polydimethylsiloxane (PDMS) functionalized with diisocyanate. The influence of PDMS contents on the properties of copolymers was studied. Differential scanning calorimetry and X-ray diffraction were used to investigate the melting temperature, crystallization temperature and crystal form of samples, and the results showed that the crystallinity of polymers decreased. The mechanical properties of samples were studied by notched-impact testing and tension test. The notched impact strength was improved by 200% with PDMS concentration up to 4 wt%. The form of scaly was seen by scanning electron microscope proved the improvements of the impact strength of the copolymer. The water contact angles test showed that the surface tension of copolymers decreased with the PDMS content increasing and the surface of copolymer changed from hydrophilic to hydrophobic.

Their lifetime is limited to a few production cycles due to contamination with the diisocyanate component of polyurethane casting materials. Using thermogravimetric analysis measurements, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and helium-ion-microscopy the chemical and physical mechanisms of the aging process have been identified. It has been shown that a diffusion process of diisocyanate into the cavity surface leads to the formation of interpenetrating polymer networks of polyurea derivatives in silicone rubber. This has been proven by extracting and analyzing polyurea of low molecular weights from the silicone.

The kinetic of isothermal crystallization could be well defined by Avrami equation, while Mo model was successful to describe the nonisothermal crystallization. Based on the obtained kinetic parameters, poly(cyclohexene carbonate) segments not only act as a nucleating agent accelerating nucleating rate but also restrict the transport of poly(ε-caprolactone) segments decelerating growth rate. The mechanical properties of polymers were investigated using DMA and nanoindentation. It shows that the insertion of hard poly(cyclohexene carbonate) segments improves Young’s modulus and heat resistance but reduces hardness of copolymers.

The polymerization process was occurred by solution polycondensation technique by the interaction of the newly synthesized monomer 3 with adepoyl, sebacoyl, terphthaloyl, and isophthaloyldiacid chlorides. Before polymerization, the structure of monomer 3 was confirmed by elemental and spectral analyses. The structures of polymers were also investigated by elemental, spectral analysis, thermal analysis, and Field-Emission Scanning Electron Microscopy (FE-SEM) micrographs. Film draw temperatures for all the polymers were evaluated in the range 509.0–542.3°C. Here, the heavy metallic sensors are developed with the polyamide-fabricated glassy carbon electrode (GCE) by reliable current vs. voltage technique. A thin layer of PA onto GCE was fabricated with conducting coating agents (5% nafion) to fabricate a selective heavy metal ions, Cu2+ sensor in short response time in phosphate buffer phase. The fabricated sensor was also exhibited higher sensitivity, lower detection limit, large dynamic concentration ranges, long-term stability, and improved electrochemical performances toward Cu2+ sensor. The calibration plot is linear (r2: 0.9956) over the large Cu2+ ion concentration ranges (1.0 nM to 10.0 mM). The sensitivity and detection limit is 3.4177 µA cm−2 µM−1 and 0.36 nM (signal-to-noise ratio of 3) respectively. This novel effort is initiated a well-organized way of efficient cationic sensor improvement with conductive polymers for heavy metallic pollutants in environmental and health-care fields in large scales.
