Polymer Characterization: Polymer Molecular Weight Determination
Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...
متن کاملReinforcement of macroscopic carbon nanotube structures by polymer intercalation: The role of polymer molecular weight and chain conformation
Novel polymer nanotube composites were fabricated by intercalating poly vinylpyrrolidone into Buckypaper from solution. This was carried out for both low 10k g/mol and very high 1.3M g/mol molecular weight polymers. Measurements of the polymer mass uptake as a function of time allowed the calculation of diffusion coefficients as 1.66 10−9 cm2/s and 3.08 10−12 cm2/s for the low and high molecula...
متن کاملBimodal distribution in branched polymer solutions
2014 We study the swelling of one very large molecule made of N monomers in a mixture of a good solvent and shorter polymers of P units of the same chemical species. All the macromolecules are branched. The total concentration is larger than the contact concentration C* of the short chains. When P decreases, the radius of gyration of the probe chain crosses-over from a N 1/3 behaviour typical o...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Canonical free-energy barrier of particle and polymer cluster formation
A common approach to study nucleation rates is the estimation of free-energy barriers. This usually requires knowledge about the shape of the forming droplet, a task that becomes notoriously difficult in macromolecular setups starting with a proper definition of the cluster boundary. Here we demonstrate a shape-free determination of the free energy for temperature-driven cluster formation in pa...
