Abstract
Dezvoltarea nanostiintei si nanotehnologiei a cunoscut in ultimii ani progrese importante, unul din motoarele propulsante fiind reprezentat de materialele nanocompozite de tip metal-polimer. Proprietatile fizice ale sistemului metalic sunt puternic afectate de efectele cuantice de dimensiune, putand prezenta, la nivelul clusterilor nanometrici, cromatism datorat absorbtiei plasmonice, foto si termoluminiscenta, feromagnetism sau superparamagnetism, activitate catalitica intensa, samd. proiectul de fata propune dezvoltarea unor metode de sinteza in plasma a nanocompozitelor metal-polimer, prin utilizarea de tehnici combinate de tipul plasma enhanced chemical vapor deposition/physical vapor deposition (PECVD/PVD), metode care conduc la nanomateriale cu proprietati predeterminate. Cercetarile tintesc obtinerea si caracterizarea de nanocompozite metal-polimer cu frecventa de rezonanta plasmonica de suprafata controlata si, de asemenea, de nanocompozite cu proprietati antimicrobiene si/sau de biocompatibilitate. Controlul procesului combinat de sinteza se realizeaza prin identificarea si monitorarea speciilor care sustin sinteza, specii generate in timpul functionarii secventiale sau simultane a surselor de plasma. echipa propusa prin prezentul proiect, din cadrul Institutului National de Fizica Laserilor, Plasmei si Radiatiei, este formata dintr-un cercetator tanar, dar cu experienta si recunoastere internationala, precum si din cercetatori tineri doctoranzi, care urmeaza a-si finaliza lucrarile de doctorat pe parcursul implementarii proiectului.
