Desenvolvimento de um compósito a partir da mistura do pó da concha do molusco Anomalocardia brasiliana ao polietileno de tereftalato - PET, materiais de descarte na cIdade de Luís Correia/PI

Abstract

The human being has its evolution interconnected with the innovation of materials handling techniques, since the beginnings of time, visibly exemplified with the creation of tools and artifacts in general since the time of the Hominids. The evolution of society is built together with the growth of logical thinking and is consolidated over the centuries on the pillars: social, industrial and political, it has brought to men the comprehensive development in various fields, but the exacerbated evolution and consumerism unbridled caused several environmental problems in society. That way, science, according to available technologies, seeks answers to minimize environmental impacts, seeking to protect the planet and ensure the survival of humanity. Slowly, we begin to understand the evident need for a sustainable coexistence between man and the environment. In this way, the same science that encourages industries also works hard in laboratories to develop ecologically correct materials, that is, biodegradable or recyclable. Materials engineering stands out in several lines of research, among them are composites, which are materials formed from the junction of two or more materials, where their properties must be superior to the properties of their precursor materials, in this way a field of research capable of uniting materials that were wasted before and now, through study, can be molded for reuse. Polymer and ceramic (which can be oxides) are chemical definitions of substances, the chemical interaction between the two called synergism, is the expected result of this combination with improved properties for the established purposes. That way, the present work adds chemical knowledge to the research line of materials engineering composites, aiming to obtain a composite made from waste materials, which have polymeric origin and ceramic origin. The materials collected in the city of Luís Correia-Piauí for the present research are: the Polyethylene Terephthalate - PET polymer and the ceramic material comes from the recycling of shells of the bivalve mollusc Anomalocardia brasiliana (Gmelin, 1971), resulting from the disposal of Malacoculture, in this way, we obtained the formulation of a composite with future purposes of a possible application in the area of ecological materials to be used in civil construction, or similar sustainable areas, at the same time this research will serve as a basis for studies and views on materials already that are discarded, thus ensuring the maintenance of a sustainable social cycle, capable of guiding the populations of cities to a new level of survival towards nature
