Abstract
The present invention relates to an adhesive composition containing at least a polymer and an ionic liquid, in which when an adhesive layer is formed of a composition composed of components other than the ionic liquid among components contained in the adhesive composition, the adhesive layer has a relative permittivity of 5 or more at a frequency of 100 Hz, after being left to stand in an environment of 22° C. and 20% RH for 3 days.
Claims15
An adhesive composition comprising:
- a polymer;
- and
- an ionic liquid, wherein
- when an adhesive layer is formed of a composition composed of components other than the ionic liquid among components contained in the adhesive composition, the adhesive layer has a relative permittivity of 5 or more at a frequency of 100 Hz after being left to stand in an environment of 22° C. and 20% RH for 3 days.
An adhesive composition comprising:
- a polymer;
- and
- an ionic liquid, wherein
- when an adhesive layer is formed of the adhesive composition, the adhesive layer has a capacitance per unit area of an interface between the adhesive layer and the aluminum plate of 0.9 μF/cm2 or more, and has an ionic conductivity of 10 μS/m or more after being adhered to an aluminum plate made of A5052P H32 in JIS H4000:2014 and left to stand in an environment of 22° C. and 15% RH for 7 days.
An adhesive composition comprising:
- a polymer;
- and
- an ionic liquid, wherein
- the adhesive composition contains 0.5 to 30 parts by mass of the ionic liquid and 0.5 to 10 parts by mass of an ionic solid per 100 parts by mass of the polymer.
An adhesive composition comprising:
- a polymer;
- and
- an ionic liquid, wherein
- the adhesive composition contains 0.5 to 30 parts by mass of the ionic liquid per 100 parts by mass of the polymer, and the polymer contains 0.05 to 2 parts by mass of an ionic polymer.
An adhesive composition comprising:
- 100 parts by mass of an acrylic polymer;
- and
- 0.5 to 30 parts by mass of an ionic liquid, wherein
- a proportion of a polar group-containing monomer to total monomer components constituting the acrylic polymer is 0.1 to 35% by mass.
