Interfacial Compatibility

Monomer casting polyamide 6 (MCPA6) was modified by zeolite whose microstructure owns nanoscale holes which has excellent interfacial compatibility with MCPA6. The zeolite / MCPA6 composites were prepared by anionic in-situ polymerization. FTIR indicated that the addition of zeolite did not cause adverse reaction in the reaction system. The results also showed that zeolite / MCPA6 composites had two melting peaks; MCPA6 transformed from α crystal to γ crystal structure partly. The zeolite played a role of heterogeneous nucleation agent which improved the crystallinity of MC nylon 6. When the addition of zeolite was 5 phr, the zeolite / MCPA6 composite crystallization temperature increased over MCPA6 6.8 °C.

The Impact

Zeolite / MC nylon 6 composites were prepared , followed by morphology and properties characterization of composites. The results demonstrated that a large number of pearlitic structures appeared at the interphase between the organic phases and the inorganic phases, indicating that caprolactam had happened anionic in-situ polymerization within the zeolite. The zeolite played a role of molecular rivet in zeolite / MCPA6 composites. The experimental results also showed that the composites performances were largely improved compared with pure MCPA6. When zeolite was 1 Phr, the impact strength of the composite was increased by 58%, temperature of thermal decomposition was rised by 92.9 °C. When zeolite reached 5 Phr, the composite shrinkage rate was reduced by 33%.

The PANI/ITO conducting nanocomposites have been synthesized by in-situ polymerization. The obtained nanocomposites were characterized by X-ray diffraction pattern, scanning electron microscopy and Fourier transform infrared. Electrical conductivity measurements on the samples pressed into pellets showed that the maximum conductivity attained 2.0 ± 0.05 S/cm for PANI/ITO nanocomposites, at ITO doping concentration of 10 wt%. The results of the present work may provide a simple, rapid and efficient approach for preparing PANI/ITO nanocomposites.

Interface Layers

To overcome the limitations of large-scale applications for MOFs in the powder form, herein, we proposed a strategy of in-situ growth ZIF-8 onto polyaniline (PANI) modified coconut hydrogel (CCH). Firstly, PANI played the role of metal chelated layers, which were coated on CCH by in-situ polymerization. Then, ZIF-8 nanocrystals were in-situ growth on the surface of the PANI coated CCH to synthesise the composite adsorbent ZIF-8/PANI/CCH. Finally, after vacuum freeze-dried, a white and well structured ZIF-8/PANI/CCA(ZIF-8/polyaniline/coconut aerogel) was obtained. The loading mass ratios of ZIF-8 on CCA and PANI/CCA were 11.3% and 37.5%, respectively, which indicates that PANI as interface layers can effectively promote the in-situ growth of ZIF-8. The obtained composite adsorbent (ZIF-8/PANI/CCA) was applied for the adsorption of tetracycline (TC)，and the removal efficiency reaches over 91.6%. This strategy may provide an effective and versatile pathway to increase MOF loading mass on natural polysaccharide aerogel and sequentially branch out their applications in pollutant treatment fields.
