Development of polymeric sustainable materialsusing nanotechnologyLuiz Henrique Capparelli Mattoso1, Caio Gomide Otoni1, Marcos ViniciusLorevice1, Francys Kley Vieira Moreira1, José Manoel Marconcini1, Cauê RibeiroOliveira11Embrapa Instrumentaçãoe-mail: luiz.mattoso@embrapa.brEnvironmentally  inspired  strategies  have  been  explored  throughout  the  lastdecades aiming at developing sustainable alternatives to replace petroleum-basednon-biodegradable materials. Our group has been investigating several naturalpolymers (e.g., pectin, starch, and cellulose derivatives) as well as organic andinorganic  nanoreinforcements  (e.g.,  chitosan  nanospheres,  cellulose  whiskers,and layered clays) to produce bio-based materials with improved thermal andmechanical performances. Edible films, for instance, have been studied to providenovel edible food packaging without any health concern to consumers, while alsobeing  biodegradable  and  obtained  from  renewable  sources.  We  have  beeninvestigating fruit purees (e.g., mango, guava, papaya, and banana) to developinnovative  edible  bioplastic  films  with  unique  color  and  flavor.  Additionally,nanotechnology concepts have been applied on edible films as an effort to makethem reach the physical-mechanical properties of synthetic polymers used in foodpackaging.  Previous studies  on chitosan nanoparticles  and cellulose whiskerswere conducted in that regard. Antimicrobial substances (e.g., plant essential oilsand their active compounds) have also been incorporated to provide the ediblefilms with  antimicrobial  properties  to  extend food shelf  life  and ensure foodsafety. This lecture will also cover the production of new bionanocomposites frommultifunctional  nanoparticles  and  their  future  outlooks  of  application  insustainable  technologies.Acknowledgements  Embrapa,  FINEP/MCT,  CNPq,  and  FAPESP  (Process  n°2010/11584-5,  n°  2012/21867-0,  n°  2012/24362-6,  n°  2013/14366-7,  and  n°2014/23098-9). 1857XIV Brazil MRS Meeting - Rio de Janeiro, from 27 September to 01 October, 2015
