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 latexesare showed. The investigated waterborne latexesinvolve proteins/acrylic and melamine/acrylic systems for coating applications and vinylcaprolactambased nanogels for transdermal delivery uses.Recent advances in the design and preparation of protein based latexesare presented, employing either casein or collagen as natural proteins. Novel approachesfor synthesizing waterborne proteins based latexes allow the incorporation of large content of biomaterialwitha 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 controlcrosslinking degree as well as the properties of final coalesced films.Thermosensitive nanoparticlesare interesting candidatesin several biomedical applications. The development of a waterborne hybrid nanogelsbased on vinylcaprolactam with film forming ability with high cohesive strength arefinallyconsideredas an emerging alternative for their potential application intransdermal delivery.
