Abstract
A sulfonated bamboo charcoal-chitosan (sBC-CS) hybrid was applied to develop a biopolymer for natural rubber reinforcements. The copolymerization was conducted with chitosan (CS) and sulfonated bamboo charcoal by a sulfonation reaction method. The obtained sBC-CS was characterized by FTIR, X-ray diffraction, dispersion rate analysis, field-emission electron microscopy, and thermal gravimetric analysis. In comparison to pure chitosan, a greater thermal stability of sBC-CS was observed. In addition, sulfonated bamboo charcoal-chitosan (sBC-CS) hybrid reinforced natural rubber composites were produced, and sulfur was used as a vulcanizing agent. Their vulcanizing and mechanical properties were characterized. Comparing to the pure chitosan filled natural rubber composites, the sBC-CS reinforced natural rubber composites showed improved mechanical properties, indicating the this material's potential application for rubber reinforcements.

술폰화된 뱀부차콜-키토산(sulfonated bamboo charcol-chitosan, sBC-CS) 혼성체가 천연고무 보강을 위한 바이오고분자를 개발하기 위하여 적용되었다. 공중합은 키토산과 술폰화 반응 방법에 의해 술폰화된 뱀부차콜과 함께 수행되었다. 얻어진 sBC-CS는 FTIR, X-ray 회절, 분산속도 분석, field-emission electron microscopy 및 열무게 분석법에 의하여 분석되었다. 순수한 키토산과 비교하여, sBC-CS의 더 좋은 열안정성이 관찰되었다. 또한 sBC-CS 혼성체로 보강된 천연고무 복합체가 제조되었고, 황이 가교제로 사용되었다. 가황된 복합체의 기계적 물성이 측정되었는데, 순수한 키토산으로 충전된 천연고무 복합체와 비교할 때 sC-CS로 보강된 천연고무 복합체가 개선된 기계적 물성을 보여서, 이 물질이 중요한 고무 보강재임을 나타내었다.
