Rationally Tunable Phase Change Material Thermal Properties Enabled by Three-Dimensionally Printed Structural Materials and Carbon-Based Functional Additives

Figure 3

Morphological analysis of 3DS-TEMCs constituents. SEM images of (a) 3D-printed TPE backbones, (b) MWCNTs, and (c) GNPs before integrating them into the 3DS-TEMCs. Cross-sectional images of (d) the locally hybridized TPE backbones and the PCM nanocomposites consisting of octadecane and MWCNT/GNP functional additives. The dark- and light-gray areas classified by yellow lines indicate the TPE backbone and the PCM nanocomposites, respectively. Disassembled structural images of 3DS-TEMCs with infill density/MWCNT/GNP of (e) 60%/6%/1% and (f) 60%/8%/1%.
