Does sputtering Au on top of PEDOT:PSS thin film alter its properties?
I have grown thin films (~100-500 nm) of PEDOT:PSS by electrodeposition on top of thin films of Au (~1 nm) and now I want to measure the impedance of the PEDOT:PSS thin film.
To accomplish this I am ...

How does contraction of polyethylene strip depend upon the heat it receives?
Strip is made of polyethylene and is cold drawn so that all polymer chains are oriented in one direction. Now, if heat is supplied to it via external source then how much will this strip contract. Is ...

Exploring potential landscape with Monte Carlo
I am using a Monte Carlo approach for studying folding of a polymer chain. The polymer may fold in many configurations, corresponding to local potential minima, studying which is what interests me (i....

Temperature dependence of rubber elastic modulus
Why does the elastic modulus of rubber increase with temperature? I read the article on rubber elasticity and it showed that the modulus increases with the temperature (rubber shrinks as heated). But ...

Entropy due to linearization of Freely-Jointed Chain
Say I model a polymer as a freely jointed chain in 3D with N bonds of length L each one. If I stretch the chain (initially coiled) along a 2D surface until it becomes linear (basically a 1D line of ...

Can the UV degradation of polymers be calculated?
Is it possible to calculate the mass lost due to the UV degradation of polymers (like PET or LDPE)?
I have found no information regarding equations or formulas which would provide an answer.
Any ...

Solids are crystalline or amorphous. Where do polymers fit in?
Traditionally, solids are classified as being either crystalline (well-ordered, periodic lattice structure at large spatial scales) or amorphous (disordered structure).
A well-ordered polymer is a ...

What is the link between the meaning of excluded volume and its mathematical derivation?
When we examine real polymer chains we have to consider the interactions between single monomers. Therefore we consider a Lennard-Jones-like potential for bringing two monomers together and calculate ...

One-dimensional polymer (Gibbs canonical ensemble)
Let's consider a polymer that is formed by an horizontal linear chain of $N$ disc-shaped monomers. Each monomer can either adopt either a vertical alignment (with length $l_1$ and energy $E_1$) or an ...

Is there any connection between instantons and surface-interacting polymers?
Excluded volume polymers interacting with a penetrable hypersurface of variable dimension is a very interesting system to study critical behavior via perturbative renormalization. Since a penetrable ...
