Dear Khaled ,
Thank you for your answer ,
the metal shape memory alloys is depend on compacting pressire and sintering temperature , and the alloys is return to orginal shape but in polymer (from your answer ) we show that is differnt parameter , can you give more explain ?
Regards
Dear Kadhim
The parameters of polymer shape memory alloys are those of the polymer of being semiconductor/conductor materials. External parameters such as temperature ,illumination intensity, light harvesting materials, and so on. Structural parameters like high occupied molecular orbits (HOMO), low unoccupied molecular orbit(LOMO), The energy difference between the HOMO and LUMO, the HOMO–LUMO gap, materials, cathodic metals/alloys, and so on.

Dear Kadhim
I have assumed that you were asking about Polymer/Metal composites for optoelectronic applications, I.e., semiconductor/conductor materials for organic Photovoltaic (OPV) and so on . If my assumption was not correct, then the given parameters should be different.
The mechanical properties and shape memory effect parameters of new porous TiNi alloys for implantation and prothesis were reviewed. Their porous structure provides excellent ingrowth in living tissue and firm fixation. Due to their generally good biocompatibility, these materials can serve in the body for a long time without being removed. Two manufacturing methods of porous TiNi are described here, powder sintering and ignition synthesis. Porous TiNi alloys manufactured using these methods exhibit superelasticity and shape memory effect, the parameters of which strongly depend on the conditions of sintering or synthesis. Under certain conditions, these parameters approach those of solid alloys. The yield strength, the percent of shape recovery, and the stored recoverable strain are controlled by porosity. Higher porosity and low average magnitude of plastic deformation result i in a higher percent of shape recovery and recoverable strains.
