Waterborne polyurethane‐acrylate‐polyaniline: Interfacial hydrogen bonding for enhancing the antistatic, damping, and mechanical properties

Abstract: Damping coatings can convert kinetic energy into other forms of energy for consumption and have been widely used for vibration and noise reduction in rail trains, aerospace, automobile industry, and other fields. However, many aspects of damping coating such as, damping, water resistance, heat resistance, mechanical properties and antistatic properties require further improvement. In this study, a low‐cost conductive polyaniline (PANI) with a simple preparation method was dispersed in N‐methyl pyrrolidone and … Show more

“…Such enhanced strength should be mainly benefited from the newly formed MXene-polymer hydrogen bond network, which improves the intermolecular force within polymer matrix. [37,38] Meanwhile, the electrochemical window of SPEs was evaluated by linear sweep voltammetry (LSV) test. As revealed in Figure 2b, the PH/MXene SPE possesses a nearly 3.2 V stable working voltage window, which is higher than that of the PH SPE (3.0 V).…”

“…[ 34 ] Absorption bands at 1650—1780 cm –1 and 1550—1650 cm –1 are attributed to the stretching vibration of C=O and C=N bonds, respectively. [ 35 ] In contrast to 150‐CDs, re‐150‐CDs exhibited enhanced N—H and O—H stretching vibration signals, while the vibration signals of C=O and C=N were significantly decreased. Thus, it can be inferred that the reduction of surface structure can efficiently weaken the electron‐withdrawing environment of CDs, resulting in blue‐shifted absorption bands.…”

“…Many properties of polyurethane are affected by its unique micro‐phase separation structure. Hydrogen bond analysis by FT‐IR is one of the methods to study the microphase separation of polyurethane 42,43 . By used peak fit software, the fitting curve of CO stretching vibration peak at 1800 ~ 1600 cm −1 as shown in Figure 6.…”
