Abstract
Svojstvo otpornosti na UV zračenje vrlo je važno u primjeni polimernih materijala. Kako bi određeni polimer postao otporan na degradabilno djelovanje UV zračenja, dodaju se aktivne komponente (različiti antioksidansi i UV stabilizatori) koji usporavaju ili zaustavljaju proces degradacije. U ovom radu ispitivani su kompoziti na bazi polietilena niske gustoće (LDPE) u čiju su polimernu matricu dodani metalni oksidi s potencijalnim svojstvom UV blokiranja (TiO2, ZnO i SiO2) te isti metalni oksidi uz dodatak čestica srebra. Uzorci su karakterizirani FTIR spektroskopijom i termogravimetrijskom analizom. Rezultati provedenih analiza pokazali su kako je dodatak čestica metalnih oksida povećao stabilnost i otpornost na UV zračenje polietilena niske gustoće. Manja otpornost prema degradaciji kod nekih se uzoraka pripisuje aglomeraciji dodanih metalnih oksida.
Abstract (english)
The ability to resist UV radiation is very important property of polymer materials in their common application. In order to improve resistance of polymer materials to the degradable UV activity, active components (various antioxidants and UV stabilizers) can be added to the polymer matrix in order to slow down or prevent process of degradation. In this work, low density polyethylene (LDPE) composites with metal oxides (TiO2, ZnO and SiO2) with potential UV blocking properties are characterized. The experiments were repeated and carried out with the same metal oxides incorporated in LDPE with the addition of silver particles. The samples were characterized by FTIR spectroscopy and thermogravimetric analysis. The results show that the addition of metal oxide particles increases stability and resistance of low density polyethylene to UV radiation. The agglomeration process of added metal oxides in some samples caused their lower resistance to UV degradation.
