The photo is for a thin film obtained from Ag-MC-nanocomposite. The nanocomposite was prepared using silver nitrate as a precursor, methyl cellulose as a capping agent, and plant extract as a reducing agent. This is the second time I see this amazing shape of my dried film. The shape looks like tree branches formed in a regular manner. .Does this indicate, for example, the crystalline properties or purity of AgNPs? Please, I want an explanation for this shape, especially this is the second time I see this shape after drying the film but using a different plant.
This thin film assumes the dendrintic surface morphology due to the nature of Ag-MC NPs and drying temperature and principally diffusion, nucleation, self aggression or assembly or capillary growth flow during drying. This can be because of both the Ag or MC polymer used. If this reoccured again, It means this is the stable morphology of the film

The appearance of your film does not reflect the crystal structure. You have obtained a composite. This is not an individual substance. For comparison and understanding, I will give an example of ice. Even ice with an individual water molecule, as you know, forms various patterns during crystallization on various surfaces. However, the crystal structure at atmospheric pressure and zero Celsius temperature is the same - a tetrahedral crystal lattice.
Kindly subject this to characterization using SEM, TEM,FTIR, XRD and likes to know compare, but I am sure the the properties of the composite formed stems from Ag-MC due to agglomeration/ self assembly and temp.
TEM, Particle size and shape, and SAED pattern showed poly crystalline structure.

I also made XRD, EDAX, FTIR. XRD confirmed the polycrystallinity. FTIR confirmed the formation of the nanocomposite, and EDAX showed high content of Ag.
