本論文は、廃棄コットン布を熱分解して炭素材料に変換し、エポキシ複合材料の補強材としての応用を検討した。SEMとラマン分光により、半黒鉛化炭素が綿前駆体の繊維形態と多孔質表面を保持していることを確認した。3wt%のコットン由来炭素を含む複合材料は、市販のカーボンナノチューブ複合材料と比較して、引張強度が約90%、靭性が150%向上し、摩擦特性と導電性も改善した。低コストで環境に優しい添加剤としての可能性を示す。
English
This paper introduces a circular-economy approach to convert waste cotton fabric into carbon materials via pyrolysis and evaluates their use as reinforcements in epoxy composites. SEM and Raman spectroscopy confirmed that the semi-graphitic carbon retained the fibrous morphology and porous surfaces of the cotton precursor. Composites with 3 wt% cotton-based carbon exhibited about 90% higher ultimate tensile strength and 150% higher tensile toughness compared to MWCNT composites, along with improved tribological and electrical properties. The results suggest cotton-based carbon is a low-cost, eco-friendly additive for mechanically tough, electrically active polymer composites.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では廃棄物削減と資源循環が重視されており、繊維廃棄物のアップサイクルは循環経済政策に合致する。ただし、本論文は材料科学の研究であり、直接的なGX規制や開示要件への関連は薄い。日本の製造業にとっては、廃棄物由来材料の利用がサプライチェーン全体の環境負荷低減に寄与する可能性がある。
In the global GX context
Globally, circular economy and waste valorization are key sustainability themes, aligning with ESG frameworks and resource efficiency goals. This paper provides empirical evidence on converting textile waste into high-value composite materials, which could inform sustainable materials sourcing and product design. However, it does not directly address climate disclosure or transition finance, but contributes to the broader sustainability literature.
👥 読者別の含意
🔬研究者:Materials scientists and sustainability researchers can gain insights into waste-derived carbon as a viable alternative to conventional reinforcements.
🏢実務担当者:Manufacturers in textiles or composites could explore waste cotton as a low-cost, eco-friendly additive for product innovation.
📄 Abstract（原文）
This paper introduces a sustainable circular-economy plan of transforming waste cotton fabric into useful carbon materials through controlled pyrolysis and assesses their application as epoxy composite strengthening agent. Scanning electron microscopy and Raman spectroscopy confirmed that the semi-graphitic carbon had retained the fibrous morphology and porous surfaces of the cotton precursor. Composites with 1 wt% and 3 wt% of cotton-based carbon were compared to the composites with the commercial multi-walled carbon nanotubes (MWCNTs). Cotton-based carbon composites with 3 wt% loading exhibited about 90% greater ultimate tensile strength, 150% greater tensile toughness and a moderate increase in Young’s modulus, compared to MWCNT composites. Tribological tests showed the presence of lower friction as a result of the fibrous morphology and consistent carbon-rich transfer layers. The electrical conductivity testing further indicated that carbon composites made of waste cotton came close to that of the MWCNT-based composites. These results indicate that carbon based on cotton is a low-cost, eco-friendly additive for achiving mechanically tough, electrically active, and tribologically improved polymer composites.
