Study On The Preparation And Properties Of Poly(arylene Ether Nitriles)containg Copper Phthalocyanine

Poly(arylene ether nitrile)(PEN) as a new type of engineering thermoplastics polymer materials, because of the aromatic portion and ether linkages in polymer backbone, the PEN exhibit high thermal stability, good mechanical properties, thermal oxidative stability and radiation resistance. So it comes to be possible to make the PEN as a kind of structural material, electronic material and electronic components used in aerospace, electronics and communication. In Recent years, high dielectric constant polymer-based composites have played an important role in the fields of the electronics industry. So as the matrix of the composite, PEN with low-cost production and good proCessibility receives much attention. Thus the currently great interest in using polymer as the matrix with dielectric fillers to prepare the polymer-composite materials with high dielectric constant has been used.In this article, the main research contents and results are as follows:1. Copper phthalocyanine(CuPc) carbons of excellent electrical conductivity were successfully prepared via a high temperature proCedure with heat treatment. And SEM, FTIR, and conductivity results show that the characteristic absorption peak becomes bread peek with the temperature of 700 oC, meanwhile the dehydrogenation of sample to produce a large number of free electrons and keep the phthalocyanine structure,so the conductivity of sample has been improved greatly with small length to diameter ratio.2. CuPc/polyarylene nitrile ethers(PEN) composite materials were prepared with the obtained CuPc crabons of different treatment temperatures. And the studies of morphology, thermal, mechanical and dielectric properties show that the good dispersion between PEN matrix and the CuPc with different treatment temperatures. Meanwhile, the composite materials show excellent thermal and mechanical properties as well as the improvement of dielectric properties. And then based on the study of composites with CuPc of different treatment temperature, the impact on PEN composites with the different contents of CuPc with 700 oC/8h have satisfied electrical conductivity have been studied further. And the morphology, thermal, mechanical and dielectric properties results show that the dielectric constant of composite materials reaches 8.4, which is 2.1 time of that of pure PEN.3. Based on the previous step, the MWCNTs-COOH with high strength, large length to diameter ratio and lightweight was filled in the CuPc/PEN composite materials, and the CuPc/MWCNTs/PEN composite materials were prepared via solution-casting method. And the morphology, thermal, mechanical and dielectric properties results show that the CuPc/MWCNTs/PEN composite materials exhibit the best mechanical properties with 10 wt% CuPc loading, after the filling of 3wt% MWCNTs-COOH loading. Meanwhile, the dielectric constant of composite materials reaches 18.4, which is 4.7 time of that of pure PEN and 2.2 time of that of CuPc/PEN composite materials.
