Comparison of weight loss in natural rubber latex film (rubber dam) filled nanocrystal cellulose and synthetic dyes with soil burial methods

Abstract

Biodegradation of natural rubber latex products filled with nanocrystal cellulose from peanut shell is carried out by soil burial methods with and without using fertilizer. Testing is done by calculating the loss of sample weight for 5 weeks with observation every 1 week. Samples were tested the morphology using Scanning Electron Microscope (SEM) and Fourier Transform Infra Red (FTIR). Natural rubber latex film samples showed that the loading of nanocrystal cellulose fillers from peanut shells was biodegradable faster in soil burial method with addition of fertilizer in soil compared to no addition of fertilizer.
