Abstract

The research about the effect of the addition of nano crystal cellulose (NCC) isolated from empty palm bunches (EPB) on the morphological and mechanical properties of natural rubber latex products was successfully conducted. This research was carried out in three steps: i.e isolation of α-cellulose from EPB, followed by isolation NCCs from α-cellulose using H2SO4 48.84% at 45ºC for 25 minutes, and manufacture of latex compound with varying filler NCC were 0, 0.6, 1.2, 1.8, 2.4, and 3.0. Manufacturing of natural rubber product was made with pour the NRL followed by vulcanized at 120ºC for 30 minutes. The sheet of NRL product was produced later characterized its mechanical properties through tensile test and surface morphology analysis by SEM. The optimum value of the tensile test result of the NRL product sheet was at the addition of 1,2 phr of NCC with values of tensile test, elongation at break, and Young’s modulus was 3.771 MPa, 877%, and 0.430 Mpa respectively. In addition, surface morphology analysis showed that the NCC was spread evenly.

Abstract

Isolation and characterization of cellulose nanocrystal of alpha-cellulose from Empty Fruit Bunch (EFB) have been performed. Empty Fruit Bunch (EFB) was delignificated with 3.5% HNO3 and NaNO2, precipitated with17.5% NaOH, bleaching process with 10% H2O2. Nanocrystal was obtained through the hydrolysis of alpha-cellulose using 45% H2SO4. Nanocrystal surface structures cellulose was analyzed by Scanning Electron Microscopy (SEM) and the results show that the resulting cellulose Nanocrystal size was 79 nm. Analysis of thermal degradation using Thermal Gravimetric Analysis (TGA) shows that the cellulose nanocrystal was started at 160ºC decomposes. It shows the process of cellulose nanocrystal that isolated from alpha-cellulose has occurred.
