Recently, there has been much interest in the effect of filler sizes in polymer composites. In this review, the effect of macro- and nanofillers such as palm ash, wood flour, CNTs, organoclay on mechanical properties of NR composites are discussed. 

The comparison of mechanical properties of EPM vulca-nizates filled with micrometer and nanometer sized Fe304 shows the effect of fillers size and its influence on vulcani-zates tensile strength (Fig. 6). The results suggest, that the optimal content of micro sized Fe304 is 80 phr and 60 phr for nano sized Fe304. 

In order to study the effect of filler size distribution, it is necessary to work with uniform monodisperse particles. These would have to be available in different sizes so that controlled mixtures of two or three different sizes can be studied. There are various methods of getting uruform-sized particles and these have been discussed in a number of articles [102-106].

The reliability curves in Fig. 10(g) to (i) show the effect of filler size on the joint reliability. These adhesives are all filled wifh nickel/gold coated plastic particles. It seemed that hllers larger than 5 pm had negative effect on the joint performance. With these pastes, joints could fail rather early in the test, though their MTF values were quite high. 

Observations on the interfacial retardation, decay of retardation with distance from the filler, effect of filler size, and the dependence on Flory-Huggins x parameter are in quantitative agreement with the theory. Additional data on the effect of crosslink density indicate that cohesive failure of elastomer at low cross-linking and non-Gaussian network statistics and/or failure at high crosslinking must be taken into consideration.
