It very much depend on the polymer building blocks than on being thermoplastic or thermoset and the media that the polymer is going to expose to. I suggest to clearly define the solution that polymer is going to be in contact and check the resistant of different desired polymers to that certain chemical/condition.

Hi Mostafa, the absorption capacity of a polymer is governed by various factors, such as functional groups, absroption conditions, porosity, etc. Thermoset polymers are cross-linked polymer and therefore the produced polymer is highly amorphous. On the other hand, thermoplastic polymers could be highly crystalline. If the other factors are same, the thermoset polymers should have higher absorption capability compared to the thermoplastic polymers.

As mentioned by the previous colleagues, please specify the conditions and the molecules to be absorbed.

For adsorption of non-polar molecules you would go with a non-polar polymer and for adsorption of polar molecules you would go with something providing dipole of preferably hydrogen bonding towards the molecules to be adsorbed. Biopolymers are excellent adsorbents of water, but also sometimes failing with chain scissoring due their de-polymerization at weak ester bondings. Once selected polymer with the best molecular affinity for the given molecule to adsorb, you wish to go for creating porosity and surface area for adsorption.

Thank you all (Professor Amin Shavandi, Professor Mohammad Mahbubul Hassan, Professor Gyorgy Banhegyi, and Professor Richard T. Olsson )so much for your answers. Indeed, I do appreciate that.

All the best,

Mostafa

Thank you again Professors for your good sharing. Actually I am interested in removing of some textile dyes. Some of these dyes are cationic and others are anionic. The anionic dyes required acidic to neutral solutions and the cationic dyes required neutral to alkaline solutions for their removal. I am also interested in removing of some metal ions such as Fe3+, Cd2+, Hg2+, and Mn2+.

Thank you all for your interest.
