The shape of at least one predeformation on described security element makes security element can be connected with false proof object, and security element and false proof object can be made when this predeformation is recovered to depart from or partly depart from.On program basis, described security element can also have a predeformation security element can be made again to be out of shape when its recovery temperature, and the shape after being again out of shape enable the security element departing from or partly depart from false proof object again be connected with false proof object.
The method for anti-counterfeit of article of the present invention is: will false proof article (comprising article itself or its packing material) be needed as false proof object, the security element be associated with anti-false proof object is set, the matrix of security element is thermal shape memory polymeric material, and the matrix of security element arranges the corresponding predeformation of one or more with respective recovery temperature.The true and false of article is judged by the shape recovery situation of security element under different recovery temperature condition.
Described one or more predeformation can be in the process of one or many heating, the predeformation implemented under the different temperatures more than glass transition or melting transition initial temperature of this material.
When the matrix material of security element has one or more glass transition or melting transition characteristic, described one or more predeformation can be the predeformation implemented on one or more glass transition or melting transition initial temperature.
Enable security element to have at least the shape of a predeformation security element is connected with false proof object, and security element and false proof target portion can be made when this predeformation is recovered or all depart from.On this basis, security element at least also has a predeformation when its recovery temperature, security element is out of shape again, and the shape after being again out of shape enable the security element departing from or partly depart from false proof object again be connected with false proof object.
The present invention compared with prior art, has following advantageous effect:
1, the present invention carries out false proof instruction by the one or many pattern change of shape-memory polymer, and copy difficulty greatly, false proof rank is high.
2, the present invention can as required, makes multi-form (as a part for the packing of product, or a part for product self), difformity and size, the anti-counterfeiting mark of different predeformation mode realizes, thus improve further and copy difficulty.
3, thermal shape memory polymkeric substance used in the present invention can be selected from existing commercial polymkeric substance, thus can significantly reduce costs.
