I am looking for shape memory polymers. Have you any suggestions and where I can buy it?
Cf.: Jinlian Hu, "Shape memory polymers and textiles", The Textile Institute / Woodhead Publ. Ltd. (Cambridge, UK) / CRC Press LLC (Boca Raton, FL, USA), 2007.
Polyurethanes, polylactic acid (pla). These polymers can also be 3D printed. You can buy them from major distributors (Amazon) and 3D printing companies that sell thermoplastic filament. You probably want something with a fairly low glass transition temperature and melting temperature.
Abdelhaq Benkaddour I hope you're fine. I'm looking for thermoplastic SMP that I can use it as matrix for composite applications
Thermoplastic filaments which are 3D printable are available including Amazon. As for as composite is concerned, you can use Fila Extrusion system to make the composite of TP and other material.
Following is the link that takes you the previously asked question on Researchgate; I hope this will be helpful for you.

Hello Habibi Mohamed, you may want to compare the shape memory effect of the PLA (if you have few options), some works better depending on the brands. I tried PCL as well, it seems to have faster shape recovery in lower temperature compared to PLA. But if you are 3D printing it, I would still prefer to work with PLA. Hope this help.
Dear Habibi Mohamed
Visit these websites to buy SMP resin.

I hope this useful to you.
explain more detail
application?
temperature used?

Hi Habibi,
You may make an inquiry at Alfa Chemistry, they offer kinds of good-quality polymers.

Dear Habibi Mohammed,
I recommend you to search it in SMPTechnology Inc site.
You can find a wide range of SMP resins, either thermoset or thermoplastic, with detailed specification at there.
We tried their MP-5510 in our paper (https://iopscience.iop.org/article/10.1088/1361-665X/abd342/meta) and it had good ability to show onset point in the release of elastic modulus.
Good luck!
