Abstract
The invention provides a composite capable of achieving both excellent followability to an adherend and excellent adhesion. The composite has a support and a plurality of structures fixed to at least one surface of the support, and the structure has a shaft member consisting of a flexible material extending from a proximal end fixed to the support, and an adhesive part arranged at a distal end of the shaft member.
Claims13
A method of producing a composite which comprises a support and a plurality of structures fixed to at least one surface of the support, wherein the structure comprises a shaft member made from a flexible material extending from a proximal end fixed to the support, and an adhesive part arranged at a distal end of the shaft member, the method comprising:
- a step A1 of fixing proximal ends of fibers made from a flexible material to at least one surface of a temporary support at a predetermined interval from each other to obtain a temporary support with fibers;
- a step A2 of immersing at least the fibers in a composition containing a pressure-sensitive adhesive;
- a step A3 of taking out the temporary support with fibers from the composition, and obtaining a structure having a shaft member formed by bonding a plurality of the fibers by the surface tension of the composition, and an adhesive part which is formed on a proximal end side corresponding to the interval and which is composed of a film-like pressure-sensitive adhesive held or surrounded by the fibers, wherein a film means a shape having a shape such as a circular shape, a semicircular shape, a sector shape, a polygonal shape, a spherical shape, a flat spherical shape, a long spherical shape, a cylindrical shape, or a triangular columnar shape;
- and
- a step A4 of separating the structure from the temporary support, and fixing the shaft member to the support to obtain the composite,
- wherein the flexible material is a material which is elastically deformable in relation to a stress required for an initial adhesion between the adhesive part and an adherend.
A method of producing a composite which comprises a support and a plurality of structures fixed to at least one surface of the support, wherein the structure comprises a shaft member made from a flexible material extending from a proximal end fixed to the support, and an adhesive part arranged at a distal end of the shaft member, the method comprising:
- a step B1 of disposing a fiber made from a flexible material on at least one surface of a support, and obtaining a support with an annular fiber having an annular region formed by the fiber or the fiber and the surface;
- a step B2 of immersing at least the fiber in a composition containing a pressure-sensitive adhesive and filling the region with the composition;
- and
- a step B3 of removing the support with the annular fiber from the composition to obtain a structure having a shaft member formed by adhering at least a part of the fiber by the surface tension of the composition and extending from the surface, and an adhesive part which is formed at the distal end of the shaft member and which is composed of a film-like pressure-sensitive adhesive held or surrounded by the fiber, wherein a film means a shape having a shape such as a circular shape, a semicircular shape, a sector shape, a polygonal shape, a spherical shape, a flat spherical shape, a long spherical shape, a cylindrical shape, or a triangular columnar shape,
- wherein the flexible material is a material which is elastically deformable in relation to a stress required for an initial adhesion between the adhesive part and an adherend.
