Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The vacuum-filtration plus hot-pressing method is presented as a simple, low-cost route to flexible conductive MOF thermoelectric films for wearable electronics and energy conversion.
Caveat: No device-level thermoelectric generator output, scale-up batch or long-term environmental stability test is reported in the main text.

SI Table S1 presents the hot-pressed Cu3(HHTP)2 film as the current-work conductive MOF thermoelectric entry with 6.5x10-3 S cm-1 conductivity, 221.7 uV K-1 Seebeck coefficient and 3.2x10-2 uW m-1 K-2 power factor.
Caveat: Table S1 also lists literature comparison rows, which were not extracted as first-hand evidence for this paper.

The nylon substrate, submicron pore network and bonding/penetration of Cu3(HHTP)2 nanorods into porous nylon explain the film flexibility.
Caveat: Bonding mechanism is based on SEM/EDS observations rather than direct interfacial spectroscopy or mechanical peel testing.

The characteristic diffraction peak positions of Cu3(HHTP)2 hot-pressed films remain largely consistent with the powder, indicating preserved structural integrity after hot pressing.
Caveat: A new peak around 7 degrees and weakened (001) peak indicate fabrication-induced changes.

Hot pressing improves thermoelectric performance by inducing orientation in the Cu3(HHTP)2 film, giving 221.7 uV K-1, 6.5 mS cm-1 and 31.9 nW m-1 K-2 at 353 K.
Caveat: Orientation is inferred from XRD intensity/peak changes; the SI and raw diffraction data were not supplied.

Positive Seebeck coefficients indicate p-type behaviour, most likely attributed to oxygen molecular doping of water adsorbed within the MOF pores.
Caveat: The oxygen/water doping mechanism is proposed by the authors; no controlled atmosphere or quantitative dopant measurement is reported in the main text.
