Biodegradable foams possess diverse applications in smart wearables, flexible sensors, and human–computer interaction. Current sensors face the problems of inadequate stress/strain sensitivity, high density, content conductive filler. In this study, microcellular poly(butylene adipate‐co‐terephthalate) (PBAT)/polyether block amides (PEBA)@multi‐walled carbon nanotube (MWCNT) sensor exhibiting resilience, low filler was prepared via foaming molding integration. integration process, PBAT/PEBA beads achieve efficient bonding inter‐beads, where PBAT molecular chains interfacial diffusion entanglement as well PEBA improve stability mechanical properties product. MWCNT is coated on surface beads, forming a segregated structure good network by ball‐milling technique. Consequently, PBAT/PEBA@MWCNT demonstrates exceptional piezoresistive with strain response gauge factor 60.0 stress 0.1 kPa −1 . The time recovery reach 50 100 ms, respectively. Microcellular shows promising potential for detecting various human body parts, including fingers, knees, arms. This study presents an effective approach fabrication prospective application highly sensitive degradable sensors.

Sorbent materials for efficient oil-water separation are crucial due to the increasing discharge of industrial and environmental oil pollutants. Herein, we report fabrication a superhydrophobic bacteriostatic poly(triazatruxene) (PTAT)-coated melamine sponge (MF@PTAT) via one-step in situ polymerization method, utilizing strong π-π stacking interactions between triazatruxene rings skeleton. The MF@PTAT material displayed water contact angle 158.6°, high porosity, excellent compression recovery, with an outstanding ability absorb oils organic solvents, up 186.7 g/g. Furthermore, demonstrated performance separating emulsions, achieving impressive efficiency 99.3%. In addition, significant antibacterial performance, effectively inhibiting bacterial growth. combination simple superior efficiency, properties makes low-cost highly promising contaminant treatment across various applications.
