Development of Trans-1,4-Polyisoprene Shape-Memory Polymer Composites Reinforced with Carbon Nanotubes Modified by Polydopamine

Abstract: In this study, which was inspired by mussel-biomimetic bonding research, carbon nanotubes (CNTs) were interfacially modified with polydopamine (PDA) to prepare a novel nano-filler (CNTs@PDA). The structure and properties of the CNTs@PDA were studied using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). The CNTs and the CNTs@PDA were used as nanofillers and melt-blended into tran… Show more

“…This improvement can be attributed to the biochar's ability to reduce chain motion and thermal vibration, acting as an effective thermal stabilizer and preventing the complete thermal deterioration of LDPE. Similar findings have been reported in other studies that investigated the reinforcement of polymer composites with carbon structure additions [43,44]. increased, it correspondingly increased the hardness levels.…”

“…(1) Differential scanning calorimetry analysis was carried out using a Q20, TA, USA. Holding 7-8 mg of the sample at 80 °C for 3 min to eliminate the thermal history of the sample, and then the samples were cooled to −50 °C, thermostated for 5 min and then heated to 80 °C [36]. All steps are carried out in a nitrogen atmosphere with a controlled nitrogen output pressure of around 0.1 MPa and a temperature scan rate of 10 °C/min.…”

“…Therefore, the incorporation of inorganic llers as reinforcing agents in matrix materials with shape memory has become a dominant trend in SMPs today [12][13][14][15]. Common inorganic llers include carbon black (CB), silica (SiO2) carbon nanotubes (CNTs), graphene and its oxides (GO), calcium carbonate (CaCO3), carbon bers (CF), etc [16][17][18][19][20]. Organic clay (OC) can increase the tensile strength of nontensile crystalline rubber by several times due to its abundance, cheapness, and unique lamellar structure, and it has a good reinforcing function when added in small amounts [21][22][23][24][25].…”
