Enhanced Thermal and Mechanical Properties of 3D Printed Highly Porous Structures Based on γ‐Al2O3 by Adding Graphene Nanoplatelets

Abstract: logically active materials and, recently, in other emerging applications like flame retardants for polymers, quasi-solid electrolytes, or antimicrobial agents. [3] In particular, macroporous alumina with hierarchical pore structure, high surface area, and narrow pore size distribution are highly desirable for heterogeneous catalysts, as for example, hydrotreating catalysts used for heavy oils. [6][7][8] In this way, the catalytic performance can be enhanced through the development of suitable macrostructures o… Show more

“…[32,33,50,51] A recent work on γ-Al 2 O 3 -rGO structure prepared via DIW technique has reported high compressive strength around 7 MPa for relative density similar to this work. [32] However, this high compressive strength was achieved by adding very high rGO concentrations (18%). Our results demonstrate that it is possible to enhance the mechanical properties of boehmite structures by using fillers at low concentrations.…”

“…3D γ ‐alumina structures by DIW were reported for 3D composite structures of γ ‐ and α ‐alumina with carbon nanotubes, [ 7 ] Fe/ γ ‐alumina printed structures, [ 8 ] and highly porous γ ‐alumina printed structures with graphene nanoplatelets. [ 9 ] In comparison, the DLP technique is based on localized photopolymerization reactions that enable forming complex structures with a micron‐size resolution under fast printing speed without the need for support material. So far, DLP is mainly used for making polymeric objects, but in recent years, few reports have utilized it for fabricating ceramic objects.…”
