Abstract Ti 3 C 2 T x (MXene) displays prominent properties in water purification due to its rich surface chemistry and physicochemical property. However, the separation property is severely restrained because of intercalation‐induced swelling. Inspired by column‐to‐beam structure house, an advanced MXene‐based membrane developed with a stable interlayer spacing for purification. Laminar nanosheets numerous nanochannels are set as “beam” part, boron nitride (BN) thought “brick” part integrated membrane. Moreover, form interactions BN through covalent cross‐linking supramolecular hydrogen bonding. Furthermore polydopamine polyethylenimine assume roles “column” this interaction. Therefore, shows outstanding anti‐swelling 14.7 ± 0.13 Å after 600 h immersion water, which superior that most previously reported works. In addition, hydrophilic functional groups charges endow itself exceptional anti‐fouling ability. This work may offer promising manner construct materials precise

Self-Modifying Nanointerface Driving Ultrahigh Bidirectional Thermal Conductivity Boron Nitride-Based Composite Flexible Films

Nano-Micro Letters, Journal Year: 2022, Volume and Issue: 15(1)

Published: Nov. 28, 2022

While boron nitride (BN) is widely recognized as the most promising thermally conductive filler for rapidly developing high-power electronic devices due to its excellent thermal conductivity and dielectric properties, a great challenge poor vertical when embedded in composites owing interfacial interaction causing severe phonon scattering. Here, we report novel surface modification strategy called "self-modified nanointerface" using BN nanocrystals (BNNCs) efficiently link interface between polymer matrix. Combining with ice-press assembly method, an only 25 wt% BN-embedded composite film can not possess in-plane of 20.3 W m-1 K-1 but also, more importantly, achieve through-plane high 21.3 K-1, which than twice reported maximum ideal spectrum matching BNNCs fillers, strong self-modified fillers matrix, well ladder-structured skeleton. The has been verified by theoretical calculations heat dissipation CPU. This study provides innovative design principle tailor interfaces opens up new path develop high-performance composites.
