nanocompósito compreendendo polietileno e uma carga nanométrica composta por carbono ativado com níquel, processo para obtenção e uso do mesmo

a presente invenção descreve a síntese de nanocompósitos de polietileno por polimerização in situ utilizando como carga carbono ativado com níquel, que conferiram ao material propriedades magnéticas. as cargas foram obtidas a partir da pirólise da biomassa ativada com níquel. a presença do níquel me...

Beschreibung
Zusammenfassung:	a presente invenção descreve a síntese de nanocompósitos de polietileno por polimerização in situ utilizando como carga carbono ativado com níquel, que conferiram ao material propriedades magnéticas. as cargas foram obtidas a partir da pirólise da biomassa ativada com níquel. a presença do níquel mesmo em pequenos teores como 0,3% em peso confere ao material propriedades magnéticas. as propriedades mecânicas e térmicas do polímero aumentam com o aumento da carga.
