To predict the chemical structure of a grafted biopolymer with metal nanoparticles, consider factors such as the grafting method, chemical functional groups, polymer compatibility, and interaction with nanoparticles. Additionally, environmental conditions and computational simulations can aid in understanding the resulting structure and behavior.

Hello, first, the chemical structures of the two polymer samples are drawn, and the attached free groups are noted. Next, you will predict the structures using NMR and FTIR analysis. NMR analysis is used to predict the chemical structure, while FTIR analysis helps identify changes in the functional groups of the samples.

Dear Sakshi Saini, in your case structure prediction is meaningless, since both the main chain polymer and the grafts will retain their basic structure, and the only change will occur at the attachment points. NMR and other spectroscopic techniques will give the percentage and the distribution of grafts and the newly formed bonds/group. Mass spectroscopy also justify the success of grafting. For the NPs it depends on the mode of modification, is it simple adsorption or direct chamical attachment. More details are necessary to give further suggestions. My Regards
