Application of carbon nanotube and graphene nanocomposites for fabrication of micro-bolometers

Carbon Nanotube-Based Uncooled Bolometers: Advances and Progress

“…Multilayered films were spray-deposited, and their bolometric properties were studied. A maximum absolute TCR of 0.3%/K (for MWCNT film) and 0.10%/K (MWCNT/PS film) was obtained in their work . Reduced TCR of the composite BM was a result of its lower sheet resistance.…”

“…A maximum absolute TCR of 0.3%/K (for MWCNT film) and 0.10%/K (MWCNT/PS film) was obtained in their work. 187 Reduced TCR of the composite BM was a result of its lower sheet resistance. CNT concentration surpassing the percolation threshold in the composite led to reduction of the composite's overall sheet resistance and, thus, the TCR.…”

“…Nevertheless, PS incorporation reduces the thermal crosslinking among the CNTs and also provides mechanical durability to the films. 187 Coming to 2015, Wang et al fabricated a MWCNT/phase change material (PCM) nanocomposite for IR detection largely affected by thermal effects (Figure 22a). 188 In 2016, Valdivieso et al surface-functionalized MWCNT with thymine moieties and fabricated a BM on a Si substrate.…”

“…TCR values obtained in this study were a function of the number of spray deposited layer too, varying from −0.065/+0.07 (3 layers) to −0.30/–0.10 (12 layers), respectively, for MWCNT/MWCNT+PS. Nevertheless, PS incorporation reduces the thermal cross-linking among the CNTs and also provides mechanical durability to the films . Coming to 2015, Wang et al fabricated a MWCNT/phase change material (PCM) nanocomposite for IR detection largely affected by thermal effects (Figure a) .…”
