1：Experimental Design and Method Selection:

The study involved designing a woven-structured composite material to investigate triboelectrification-induced electroluminescence (TI-EL). Methods included fabricating ZnS:Cu-embedded PDMS composite films and weaving them with PTFE fibers to create a textile device. Triboelectric nanogenerator (TENG) principles were applied to understand the luminescence mechanisms.

2：Sample Selection and Data Sources:

Samples included ZnS:Cu phosphor particles (GGS 42 from Global Tungsten & Powders Corp.) and PDMS (Sylgard 184 from Dow Corning Corp.), mixed at a weight ratio of 5:5. PTFE, Kapton, and PDMS were used as friction materials for comparison.

3. List of Experimental Equipment and Materials: Equipment included FE-SEM (JSM-6701F, Jeol Ltd.), XRD (D8 ADVANCE, Bruker Corp.), bending tester (ZBT-200, Z-tec.), spectrometer (QE Pro 65000, Ocean Optics Inc.), pressure sensor, and oscilloscope (DPO 3052, Tektronix Inc.). Materials included ZnS:Cu, PDMS, PTFE, Kapton, Cu/PET films, and acrylic substrates.

4：Experimental Procedures and Operational Workflow:

The fabrication process involved mixing ZnS:Cu with PDMS, coating onto Cu/PET, curing, and weaving into textiles. Luminescence was measured under contact-separation motions using a friction system in a dark acryl box, with forces applied and light emission monitored via spectrometer.

5：Data Analysis Methods:

Data analysis included measuring luminescence intensity and spectra, comparing effects of different friction materials and forces, and using COMSOL simulations for electric potential distribution.
