<div> <p>Covalent organic frameworks (COFs) with layered architecture with open nanochannels and high specific surface areas are promising candidates for energy storage. However, the low electrical conductivity of two-dimensional COFs often limits their scope in energy storage applications. The conductivity of COFs can be enhanced through post-synthetic modification with conducting polymers. Herein, we developed polyaniline (PANI) modified triazine-based COFs via <i>in situ</i> polymerization of aniline with the porous frameworks. The composite materials showed high conductivity of 1.4-1.9 x 10<sup>-2</sup> S cm<sup>-1</sup> at room temperature with 10-fold enhancement in specific capacitance than the pristine frameworks. The fabricated supercapacitor exhibited a high energy density of 24.4 W h kg<sup>-1</sup> and a power density of 200 W kg<sup>-1</sup> at 0.5 A g<sup>-1 </sup>current density. Moreover, the device fabricated using the conducting polymer-triazine COF composite can light up a green light-emitting diode for 1 min after being charged for 10 s.</p></div>

Microcapsules containing paraffin phase change materials with MMA-MAA copolymer shell were synthesised by in situ polymerization. The Structure, diameter, encapsulation ratio of paraffin and thermal properties of the prepared microcapsules were investigated by using FTIR, ELS particle size analyzer, differential scanning calorimeter (DSC), thermogravimetic analysis (TGA). This encapsulated phase change paraffin could have good potential for energy storage.
