摘要：

Natural Rubber Latex (NRL) was compounded with 0-25 phr sago starch filler loadings. Effects of soil decomposition/degradation process on the mechanical properties of NRL films were investigated. Results showed that incorporation of sago starch decreased the physical properties of NRL composite films. As sago starch loading was increased, the physical properties of sago starch filled NRL (SSNRL) composite films decreased compared to control NRL films. The results indicated that optimum physical properties were achieved by 10 phr SSNRL composite films. Decomposition of NRL films was assessed through films mass loss and water vapor transmission rates of films. SEM analysis confirmed decomposition progress and filler agglomeration formation of NRL films as sago starch loading was increased above optimum loading. Fourier Transform Infra-Red analysis indicated doubly bonded carbon breakage in control (0), 10, and 25 phr films and carbonyl groups intensification signifying aldehyde and ketones groups' formation at the last week of soil decomposition period.
