Herein, we demonstrate that hexagonal boron nitride nanosheets h-BNNSs can be used as water dispersible lubricant additive through simple fluoride modification. The fluorination of h-BNNSs F-BNNSs is carried out via a facile ball milling of commercial h-BN microflakes in ammonia fluoride solution. The as-obtained F-BNNSs exhibit excellent antifriction and antiwear performance as water ...
