This work exploited the abundant hydroxyl group of halloysite nanotubes (HNTs) to induce acrylamide‐polymerisation modification by inverse emulsion (water‐in‐oil), resulting in polyacrylamide (PAM)‐modified HNTs. The structure and dispersion properties of the modified HNTs were analysed by a series of characterisations. As a promising application of HNTs, polytetrafluoroethylene (PTFE) reinforced with HNTs‐PAM was prepared. The mechanical and tribological properties of the HNTs‐PAM/PTFE were intensively studied. The results show that the volume wear rate of the HNTs‐PAM/PTFE reduced 97.3% relative to PTFE. The wear resistance of HNTs in filling PTFE was desirable.
