Bonding of substrates induced by ionizing radiation
A reactive polymer composition is provided, containing a (co)polymer that forms one or more reactive moities, either directly or indirectly, upon application of an ionizing radiation; and a multifunctional curing coagent, along with systems and methods for bonding substrates to one another using such a composition.
1. A system for bonding, comprising:
a first substrate having at least one surface containing a first reactive polymer composition;
a second substrate, optionally having at least one surface containing a second reactive polymer composition;
wherein the first reactive polymer composition and the second reactive polymer composition may be the same or different, and each comprises a (co)polymer that forms one or more reactive moieties, either directly or indirectly, upon application of an ionizing radiation and a multifunctional curing coagent; and
a source of ionizing radiation,
wherein the first substrate and the second substrate do not adhere to one another in the absence of the ionizing radiation.
2. The method of claim 1 , wherein the one or more reactive moieties is at least one member selected from the group consisting of free-radicals, cations, anions, carbenes, and nitrenes.
3. The method of claim 2 , wherein the one or more reactive moieties are one or more free-radicals.
4. A method for bonding using the system of claim 1 , comprising:
providing the first substrate and the second substrate to be bonded together, wherein the first and second substrates may be the same or different;
providing the first reactive polymer composition comprising a (co)polymer that forms one or more reactive moities, either directly or indirectly, upon application of an ionizing radiation and a multifunctional curing coagent, wherein the first reactive polymer composition is in contact with the first substrate, and optionally, the second substrate;
placing the first and second substrates in close proximity to one another; and
applying the ionizing radiation, thus forming the one or more reactive moities in the first reactive polymer composition which react to form a bond between the first and second substrates.
5. The method of claim 4 , wherein the one or more reactive moieties is at least one member selected from the group consisting of free-radicals, cations, anions, carbenes, and nitrenes.
6. The method of claim 5 , wherein the one or more reactive moieties are one or more free-radicals.
