The preparation of hybrid materials, namely poly(p-anisidine)@Clay (poly (pAnis)@Clay) and poly(p-anisidine)@cetyltrimethylammoniumbromide-Clay (poly(pAnis)@CTAB-Clay), prepared by oxidative polymerization process is presented. The formation of nanomaterials has been confirmed by XRF, XPS, FT-IR, and UV-Vis spectroscopy. Interestingly, the study of the optical band gap energy (E g) evince lowest value of 3.22 eV for poly(pAnis)@CTAB-Clay compared to poly(pAnis)@Clay with 3.26 eV. XRD results demonstrate that the intercalation of the poly(pAnis) into the Clay was confirmed by the increased interlayer spacing, the exfoliation and intercalation forms were affirmed in the TEM images. In addition, the electrochemical behavior indicates that the prepared nanocomposites are electroactive. These results are heartening in respect with the objective to utilize them in the field of technology and research related to the photovoltaics application.

The traditional cade oil, the "Katran", which has been widely used for long time in the decoration of drinking ceramic pottery items produced in Morocco, it has been used also during this work, for its antibacterial and deworming effects, in the manufacture of anti-biofilm drinking water pipeline. The antibacterial effect has been confirmed by adhesion tests and by microscopic observations in SEM. The manufactured pipes have good mechanical properties. Infrared spectroscopy has revealed structural changes of the exposed groups in the surface of pipes. The contact angle allows detection of possible modification in hydrophobicity and acid-base character, which may explain some variability observed after adhesion test.
