This study examines the aggregation/agglomeration of layered clay in polymer nanocomposites and discusses their influences on nanoparticle characteristics and mechanical properties using appropriate equations. The effective volume fraction, specific surface area, and aspect ratio of layers are calculated in samples containing both single and aggregated/agglomerated nanoparticles. The Young’s modulus and yield strength of nanocomposites are predicted based on the effective characteristics of layers. The aggregation/agglomeration decreases the effective levels of volume fraction, aspect ratio, and specific surface area of nanoparticles. As a result, researchers should prevent the accumulation of clay layers in nanocomposites and encourage the exfoliation of single layers causing optimal properties.
