Hybrid waterborne nanocomposities with film forming properties has gained increasing importance in recent years because of their reduced environmental impact and the outstanding properties reached by the constituents synergy. In this context, the recent results concerning the design of waterborne hybrid nanocomposities of different natures for their application as film forming latexes are showed. The investigated waterborne latexes involve proteins/acrylic and melamine/acrylic systems for coating applications and vinylcaprolactam based nanogels for transdermal delivery uses.Recent advances in the design and preparation of protein based latexes are presented, employing either casein or collagen as natural proteins. Novel approaches for synthesizing waterborne proteins based latexes allow the incorporation of large content of biomaterial with a high degree of compatibilization between both components. These advances have opened new possibilities for the industrial application of these hybrid materials in the field of water-based coatings. Crosslinkable latexes aim to improve the physical properties of coalesced latex films over the levels attainable with a thermoplastic latex. In this scenario, the production of waterborne acrylic/melamine nanocomposites with post-crosslinking capability are also presented. Variation of acrylic composition proves to control crosslinking degree as well as the properties of final coalesced films.Thermosensitive nanoparticles are interesting candidates in several biomedical applications. The development of a waterborne hybrid nanogels based on vinylcaprolactam with film forming ability with high cohesive strength are finally considered as an emerging alternative for their potential application in transdermal delivery.
