Characterization of biodegradable mulch black films incorporated with organics fertilizers and rice husk ash. In: TMS ANNUAL MEETING AND EXHIBITION, 146th, February 26 - March 2, 2017, San Diego, CA, USA. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/29132.http://repositorio.ipen.br/handle/123456789/29132The effects of organic fertilizer, rice husk ash, both from renewable resources, were evaluated. Both of them were incorporated in biodegradable black mulch films. Morphological, mechanical and thermal properties based on PBAT/PLA composites with 2 % wt. of carbon black were investigated. In addition, the formulations were prepared with 1 % wt. to 2 % wt. rice husk ash and 2 % wt. to 4 % wt. % organic fertilizer The samples were produced by melt extrusion process, using a twin screw extruder machine and blown film extrusion process. As can be seen the properties of biodegradable mulch film samples were investigated by tensile tests, XRD, FTIR, TG, MEV analyses. Correlation between properties were discussed. According to the results it is possible to apply this composite as film for agricultural protection.openAccessbiodegradationfilmsfertilizersorganic compoundscarbon blackpolymersTexto completo de eventohttps://orcid.org/0000-0002-7968-2117
