The electrical properties of conducting polymer and insulating polymer matrix combined with attractive mechanical properties and processing advantages of the polymers has now attained a level of maturity consistent with a new set of opportunities to develop a wide range of application based conducting polymer composites. Polyaniline has been widely investigated due to its low cost, easy synthesis and high electrical conductivity. The purpose of this work was to prepare high density polyethylene (HDPE)/linear low density polyethylene (LLDPE)/ polyaniline (PANI) blends with 5, 10, 15, 20 and 40 wt% of polyaniline by melt compounding in a torque rheometer. The final blends were prepared with a blend ratio of 1:1 HDPE/LLDPE. The PANI was synthesized by a following a well-established method for the synthesis of the emeraldine base form using HCl as dopant. The HDPE/LLDPE/PANI blends were analyzed by FTIR, mechanical, thermal and electrical properties. Usually, polymer blends with PANI were prepared by solution...

The aim of this work was the study of blends of linear low density polyethylene (LLDPE) and an ethene-propene-1-butene terpolymer (t-PP). Two types of polyethylene were used to prepare the blends: an ethene-co-1-hexene (LLDPE(H)) copolymer and an ethene-co-1-octene (LLDPE(O)) copolymer. These copolymers present similar comonomer contents, molar mass, molar mass distribution and catalyst systems, but differ in their comonomer distribution. The blends were obtained through mechanical mixing using ...

Abstract The dynamic and steady state behavior of metallocene linear low density polyethylene (m-LLDPE) blended with metallocene high density polyethylene (m-HDPE) and with low density polyethylene (LDPE) were measured in parallel plate rheometer at 160, 180, and 200 °C. The composition dependence of zero shear viscosity η 0 , the characteristic relaxation time τ 0 and the characteristic frequency ω 0 of m-LLDPE/m-HDPE blends show a linear variation in the whole range of weight fraction, which i...

This lecture is not directly related to our discovery and development of conducting polymers to which the Nobel Prize in Chemistry in 2000 was awarded. However, I would like to present my previous work that I had carried out just before we reached the discovery of chemical doping. I do hope my talk will be of use for you the audience to deepen your understandings by learning what had happened before and how we did reach the idea of chemical doping.

Abstract Hildebrand solubility parameters ( δ ) at elevated temperatures were computed for models of high-density polyethylene (HDPE) and a series of butene-based linear low-density polyethylene (b-LLDPE) with different branch contents using molecular dynamics simulation. And the δ values were then used to calculate the corresponding Flory–Huggins interaction parameter ( χ ) between HDPE and various b-LLDPE models. The results indicate that the level of branch content of b-LLDPE that is required...

In this communication, we report that aniline can be conveniently polymerized directly into conducting material using an emulsion polymerization technique. The polymerization is carried out in non-polar or weakly polar solvents in the presence of a functionalized protonic acid that acts simultaneously as a surfactant (emulsifier) and as a protonating agent (dopant) for the resulting electrically conducting polyaniline. It was found that the present direct, one-step preparation of polyaniline-pro...

The emeraldine salt form of polyaniline, conducting in the metallic regime, can be synthesized electrochemically as a film exhibiting a well defined fibrillar morphology closely resembling that of polyacetylene. Cyclic voltammograms of chemically synthesized and electrochemically synthesized polyaniline are essentially identical. Probable chemical changes which occur and the compounds which are formed when chemically synthesized poly-aniline is electrochemically oxidized and reduced between –0.2...
