The invention discloses a medical
external fixation multilayer material with shape memory and high
thermal conductivity. The medical
external fixation multilayer material with shape memory and high
thermal conductivity comprises a
polycaprolactone external fixation layer and a medical
silicone rubber inner layer. The preparation method comprises: firstly, preparing a mixture A by uniformly mixingthe following components in parts by weight: 100 parts of
polycaprolactone, 20-30 parts of
polyethylene oxide, 5-10 parts of glycerinum, 1-5 parts of a
graphene nanoplatelet supported by nano-silver,0.1-1 part of a cross-linking agent, and 0.05-0.3 parts of a
photodegradation accelerator; preparing a mixture B by uniformly mixing the following components in parts by weight: 100 parts of siliconerubber, 1-5 parts of the
graphene nanoplatelet supported by nano-silver, 0.05-0.3 parts of the
photodegradation accelerator, and 0.1-1 part of the cross-linking agent; and then subjecting the mixtureA and the mixture B to coextru-lamination by a multi-layer co-extruded plastic sheet
machine, subjecting an obtained double layer
metal board to cross-linking by
ultraviolet light irradiation, and obtaining the medical external fixation multilayer material with shape memory and high
thermal conductivity. The medical external fixation multilayer material with shape memory and high thermal
conductivity, prepared with the method, has the advantages of light weight, comfort,
environmental protection, low price and the like.
