Method of curing thermoplastic polymer for shape memory material |
摘要 |
A method of preparing a cured thermoplastic material includes curing a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200° C., at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. A method of making a shape memory material also includes curing a thermoplastic polymer to prepare a cured thermoplastic material. |

1. A method of preparing a shape memory material, the method comprising:
compounding a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200° C., with a crosslinker, and optionally, an additive, to form a mixture; compacting the mixture at room temperature; heating and curing the compacted mixture at a temperature of about 300 to about 400° C., for a heating time of less than or equal to about 72 hours to cure the thermoplastic polymer; compression molding the cured thermoplastic polymer; and de-molding at a temperature greater than or equal to about the glass transition temperature of the cured thermoplastic polymer. |
