Pengaruh Aging pada Film Lateks Karet Alam Berpengisi Nanokristalin Selulosa dan Penyerasi Alkanolamida

Abstract

Sugarcane bagasse is potential lignosellulosic waste and contains cellulose. Cellulose from sugarcane bagasse can be derived into nanocrystalline cellulose by acid hydrolysis process. This research studied about the ressistance of natural rubber latex film filled with nanocrystalline cellulose and alkanolamide compatibilizer toward aging treatment. Synthesis of nanocrystalline cellulose and alkanolamide had been done, also mechanical testing after aging treatment such as tensile strength, elongation at break and tensile modulus. Natural rubber latex film was produced by using coagulant dipping method. This research was started from natural rubber latex pre vulcanization at 70 oC and followed with vulcanization process at 100 oC for 20 minutes. Then, aging treatment was done at temperature 70 oC for 24 hour. The result of TEM and XRD characteristic of nanocrystalline cellulose show diameter of nanocrystalline celllulose was 40-160 nm with crystallinity 92,33%. The result of mechanical properties show natural rubber latex film filled with nanocrystalline cellulose and alkanolamide have a good ressistance of aging. The result of mechanical properties were supported by Scanning Electron Microscopy (SEM) which showed natural rubber latex film filled with nanocrystalline cellulose and alkanolamide compatibilizer after aging treatment have less crack on fracture surface compared to natural rubber latex film without nanocrystalline cellulose filler and alkanolamide compatibilizer.
