In this chapter, we present an overview of the development of novel soft, nanohybrid materials (e.g., nanocomposite gels [19, 21, 28-30] and soft polymer nanocomposites [31-33]) with unique organic-inorganic network structures that overcome the previous limitations and exhibit excellent optical and mechanical properties in addition to outstanding new characteristics. 

In another work of the same authors, dodecylamine modified clay was applied for the modification of the UP-based gel coat system [12]. The best mechanical properties were observed for nanocomposite gel coat with 2wt% clay, including an increase in tensile and impact strength, respectively, by 21 and 33% compared to the conventional gel coat. Further increase in organically modified montmo-rillonite (OMMT) content leads to the decrease of the strength values. The nanocomposite gel coat system showed better water absorption resistance than the conventional UP gel coats.
