Nickel foam is
low density permeable material with numerous applications. The defining characteristic
of these foams is a very high porosity, typically 75-95% of the volume consisting of
void spaces. Ceramic foam is often used for thermal insulation, acoustic insulation,
adsorption of environmental pollutants, filtration of molten metal alloys, and as
substrate for catalysts requiring large internal surface area. Nickel foam is
generally immediately available in most volumes.

Copper foam is
a new multifunctional material with a large number of connected or unconnected holes
evenly distributed on the matrix. Copper foam has good conductivity and malleability.
It has lower cost and better conductivity than nickel foam and can be used to prepare
battery anode (carrier) materials, catalyst carriers and electromagnetic shielding
materials. Copper foam has good mechanical properties and processability, great
electric and thermal conductivity and the structure has a large number of pores, but
the alkali resistance, tensile strength and malleability of metallic copper are still
exist, coupled with its good electromagnetic shielding and noise absorption function,
copper foam has a wide range of applications.

Fe foam alloyed
with phosphorus was prepared with the aim of enhancing the mechanical properties and
manipulating the corrosion rate. Two different types of Fe-P foams containing 0.5 wt.%
of P were prepared: Fe-P (I) foams from a phosphated carbonyl iron powder and Fe-P
(II) foams from a mixture of carbonyl iron and commercial Fe 3 P.

Conductive
foam is similar to standard packaging foams but with one crucial difference – the
addition of carbon to the polymer mix during the manufacturing process to provide a
high level of conductivity. This allows any electric current to pass through the cell
structure of the foam and away from the component. Generally, the foam will have
permanent conductive performance, meaning it is ideal for multi-trip packaging and
in-plant handling applications. Its performance isn’t affected by atmospheric
conditions.

Conductive
fabric is a kind of material that is made from, coated or blended with conductive
metals including but not limited to gold, carbon, titanium, nickel, silver, or copper.
Base fabric materials include cotton, wool, polyester, and nylon. There are two main
categories of conductive fibers according to the Conductive Fiber Manufacturers
Council. The first category are "intrinsically conductive fibers and conductive
polymers which constitute the largest portion of the industry, with carbon fiber being
the biggest portion." while "the second group includes non-conductive or
less conductive substrates, which are then either coated or embedded with an
electrically conductive element, often carbon, nickel, copper, gold, silver, or
titanium.”

fabric with a conductive pressure sensitive adhesive (PSA). This reliable tape design
provides outstanding shielding performance while offering superior abrasion and
corrosion resistance under high dynamic flex conditions.
