The invention relates to a
radiation protection
polyester fiber on the basis of mechanically exfoliated
graphene. The
radiation protection
polyester fiber is characterized in that
flake graphite is exfoliated in
ethylene glycol by the aid of micro-mechanical exfoliation processes to obtain
graphene, dispersing agents are added into the
graphene to form uniform, stable and dispersed graphene /
ethylene glycol solution, then the graphene /
ethylene glycol solution which is used is a
raw material is polymerized in an in-situ manner to obtain high-dispersibility graphene /
polyester, and
melt spinning is ultimately carried out to obtain the
radiation protection polyester
fiber on the basis of the mechanically exfoliated graphene. According to the scheme, the
radiation protection polyester fiber hasthe advantages that processes for synthesizing the
radiation protection polyester fiber are simple, the
radiation protection polyester fiber is low in cost, dispersion effects can be realized while the graphene is mechanically exfoliated, the problem of uneven dispersion of graphene in polyester melt at present can be solved, and the radiation protection polyester fiber has antistatic, far-
infrared and anti-
ultraviolet functionality and the like; the modified radiation protection polyester fiber is excellent in radiation protection performance; the prepared radiation protection polyester fiberon the basis of the mechanically exfoliated graphene can be widely applied to the fields of home textiles, dressing clothes, armies and the like.
