The two-dimensional (2D) material of graphitic carbon nitride (g-C3N4) has shown great promise for tribo-materials due to special mol. structure. In this work, we report an effective approach to enhance anti-wear of thermosetting polyimide (TPI) by filling with g-C3N4 under high temperature TPI composite (TPT-1) and g-C3N4 were firstly prepared Then, friction and wear behavior of TPT-1 was studied and comparatively evaluated with neat resin from room temperature to 350 °C. As a result, the wear resistance of TPI was able to significantly improve and a much lower wear rate (7.29 × 10-7 mm3/N m) was achieved at 350 °C. Moreover, the mechanism of friction and wear demonstrated that a transfer film formed by introducing g-C3N4 with high E-modulus and hardness could effectively share the load with TPI and prevent further abrasion of resin in contact surfaces. This work could help researchers to design a new TPI tribo-material used at high temperature3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.
3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Reference of 3-(4-Aminophenoxy)anilineEthers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.
