Epoxy composite material containing polyaniline/carbon black and preparation method thereof
View Patent ↗An epoxy composite material containing polyaniline/carbon black composite and preparation method thereof are disclosed. The epoxy composite material containing polyaniline/carbon black composite includes a plurality of polyaniline/carbon black composite with core-shell structure distributed in epoxy resin while polyaniline covers on surface of nanoscale carbon black to form the polyaniline/carbon black composite with core-shell structure. The polyaniline/carbon black composite with core-shell structure contains 10 to 30 wt. % of nanoscale carbon black.
1. An epoxy composite material containing polyaniline/carbon black composite comprising:
a plurality of polyaniline/carbon black composite with core-shell structure distributed in epoxy resin;
wherein polyaniline covers on surface of nanoscale carbon black to form the polyaniline/carbon black composite with core-shell structure;
the polyaniline/carbon black composite with core-shell structure contains 20 to 30 wt. % of nanoscale carbon black; and
wherein the weight ratio of the polyaniline/carbon black composite with core-shell structure to the epoxy resin is 3:7.
2. The composite material as claimed in claim 1 , wherein particle diameter of the nanoscale carbon black is from 10 to 80 nm.
3. The composite material as claimed in claim 1 , wherein particle diameter of the polyaniline/carbon black composite with core-shell structure is 50 to 250 nm.
4. The composite material as claimed in claim 1 , wherein preferred weight of the nanoscale carbon black is 20% of weight of the polyaniline/carbon black composite with core-shell structure.
5. The composite material as claimed in claim 1 , wherein the epoxy composite material containing polyaniline/carbon black composite is a microwave absorbing material.
6. The composite material as claimed in claim 1 , wherein the plurality of polyaniline/carbon black composite with core-shell structure are distributed evenly in the epoxy resin.
