4.4. Morphology of NRLF
Fig. 7 shows the SEM image of the resultant natural
rubber latex foam at 50 K magnification. It can be seen thatthe 100–122 nm sized silver nanoparticles are embedded in
the NRLF matrix. Fig. 8(a) shows the elemental analysis by
EDX and proves the presence of silver in the NRLF matrix
treated by SNP, whereas Fig. 8(b) shows that the control
NRLF sample did not give a peak for elemental silver.
Fig. 9 shows the physical appearance of the treated and
untreated NRLF. Fig. 9(a) is the control sample of NRLF and
the color is white, whereas the treated sample (Fig. 9(b)) is
somewhat yellowish in color.
