【 摘 要 】

The surface of hexagonal boron nitride (h-BN) was modified by polydopamine (PDA) where water being used as the dispersion medium. The interaction between h-BN and pineapple leaf micro crystalline cellulose (PLMCC) was improved resulting in a PDA@h-BN-PLMCC composite powder. This facilitates interactions between h-BN and PLMCC, aligns the h-BN layers along the direction of the cellulose, and eliminates anisotropy. This novel composite powder has potential application for areas such as new thermal interface materials and protection materials for wearable devices.
