Owing to setting up new environmentally friendly smart materials it is a really 
promising alternative. To make trivanillinylphosphate (TVP), vanillin is 
utilized. Natural starch has shape-recovery characteristics without the need 
for any prior grafting. [L. Chaunier and D. Lourdin, 2009] However, we add 
TVP to the starch to improve the cross-linking network and compensate for 
the lack of flexible chains and weak H-bonds. The polymer's dual-dynamic 
crosslinking network confers several advantages, including high self-healing 
efficiency, recyclability, the ability to alter form arbitrarily, both temporarily 
and permanently, and reusable adhesiveness. Our polymer can also be 
utilized as conductive adhesives/composites after being doped with graphite. 
To begin, we dropped phosphorus oxychloride into a vanillin and 
triethylamine solution in ethyl acetate at 5-10 ºC. We stirred the reaction mixture 
at 25 ºC for 24 hours after keeping it at 5-10 ºC for 30 minutes. The crosslinking 
of starch and TVP is carried out when the reaction is finished, and the SMP is 
produced. NMR spectroscopy was used to confirm the products’ structure. To 
supplement conductivity properties, graphite is added at the end. Shape 
memory, recyclability, and self-healing characteristics will all be examined. 
The produced polymer may be used as an adhesive, conductive material, 
and coating due to its multi-characteristics. [J. Mater. Chem. A, 2019]
