Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

The CPAMOF electrode and assembled TSC retain capacitance under bending and twisting, supporting flexible textile-supercapacitor use.

Caveat: Flexibility evidence is electrochemical retention under controlled deformation; wearable lifetime under real use is not tested.

4602 · Conclusions · Figures 6 and 8 · Linked to 4 structured results

Application RelevanceSupport assessment: High

The assembled symmetrical all-solid-state TSC reaches a high areal energy density of 434 uWh cm-2 at 12.5 mW cm-2.

Caveat: Device metrics are for the reported laboratory textile device; long-term packaged-device endurance beyond deformation tests is not reported.

4601 · Results and Discussion · Figure 7d · Linked to 2 structured results

CaveatSupport assessment: High

The article does not report first-hand synthesis or transport/electrochemical characterisation of a freestanding pristine Cu3(HHTP)2 control; all first-hand Cu-MOF data are from the CPAMOF composite electrode.

4596 · 2.2.3 Growth of Conductive MOFs on the CPA · Linked to 2 structured results

Composite RoleSupport assessment: High

The Au nanoparticle layer is the conductive current collector and reduces the textile sheet resistance to 1 Ohm sq-1 before MOF growth.

4598 · Results and Discussion · Figure 2a · Linked to 2 structured results

Phase AssignmentSupport assessment: High

Low-angle XRD peaks confirm successful growth of a Cu3(HHTP)2 conductive MOF layer on the fibre surface.

Caveat: No standalone pristine Cu3(HHTP)2 control pattern is reported in this article.

4598 · Results and Discussion · Figure 2b · Linked to 1 structured result

Structure Property LinkSupport assessment: Medium

The direct contact interface between conductive Cu-MOF and Au layers promotes electron transport and structural stability.

Caveat: The interface role is inferred by the authors from composite structure and electrochemical/EIS trends; no separate interfacial transport experiment is reported.

Transport MechanismSupport assessment: High

The b values between 0.5 and 1 indicate a synergistic mechanism combining diffusion-controlled and surface capacitance-controlled charge storage.

4599 · Results and Discussion · Figure 5 · Linked to 4 structured results

Transport MechanismSupport assessment: Medium

The CPAMOF electrode shows pseudocapacitive behaviour attributed to a Cu2+/Cu+ redox transition.

Caveat: Redox attribution is based on CV/GCD behaviour and literature comparison, not direct operando speciation.
