Dear Colleagues,


New polymer materials, including blends and mixtures, continue to be developed as new applications and uses are being realized.  The development of new materials often means that new polymer analysis and characterization techniques need to be developed as well.  This is necessary because the new materials have unique features that cannot be adequately measured and defined using traditional characterization methods.  Thus, the new analysis and characterization methodologies are required to guarantee that the most important property of the new materials is identified.  These developments will allow for the effective use and implementation of the novel and unique materials in challenging applications.


To allow for the dissemination and discussion of polymer analysis and characterization techniques we are interested in work that has been done in the establishment of new technologies to identify the important features of new materials.  Conversely, if an established technique has been modified or updated in some way to deal with the challenges of today, we are also interested in hearing about those results as well.


In order to achieve this goal, it is essential to collect the work of various researchers in the field of polymer analysis and characterization techniques.  Both research articles as well as reviews are welcome on this topic.


We look forward to receiving your contributions.

Published Paper

We have successfully synthesized magnetic chitin (MCH) by incorporating iron oxide nanoparticles into biodegradable and abundantly naturally available chitin by the coprecipitation method. X-ray diffraction (XRD) characterization revealed formation of cubic inverse spinel structure of Fe3O4 nanoparticles. In addition to this, other characterization studies like energy dispersive X-ray analysis (EDX) and vibrating sample magnetometry (VSM) were also performed to have an insight into the compositional and functional nature of the structure. A detailed spectroscopic study of complex impedance and dielectric constant for a wide frequency range of ~1 Hz to 10 MHz at discrete temperatures ~300–400 K has been performed by us for the first time on MCH in order to understand various relaxation processes. From permittivity, we have estimated the height of the potential barrier to be ~95.8 ± 0.3 meV. Impedance measurements yielded an activation energy of ~35.85 meV. Thermogravimetric analysis (TGA) of the sample showed exceptionally high thermal stability of the sample with percentage of residual mass at 800 ℃ being ~73% in MCH, which is quite high in comparison to the pristine chitin. An S shaped curve obtained through VSM measurement confirmed the superparamagnetic nature of the nanocomposite. The study assumes significance in the present scenario of rising awareness about the environment and demand to explore alternative green materials with numerous biomedical/environmental applications ranging from drug delivery vehicles in COVID-19 treatment to food packaging.
