E12: Compozite și Nanocompozite polimerice
Activitatea de cercetare a Echipei 12 – Compozite şi nanocompozite polimerice este orientată pe dezvoltarea de compozite şi nanocompozite polimerice multifuncţionale pe bază de polimeri sintetici şi/sau naturali şi diferite micro/nano umpluturi sintetice şi/sau naturale, cu impact redus asupra mediului sau biodegradabile şi cu proprietăţi specifice ȋmbunătăţite, impuse de diverse utilizări ȋn industrie (auto şi ambalaje), construcţii, agricultură şi biomedicină. In consecinţă, direcţiile de cercetare luate ȋn considerare sunt axate, pe de o parte, pe caracterizarea, modificarea fizică sau chimică și prelucrarea, atât a componentelor, cât și a (nano)compozitelor rezultate, iar pe de alta parte, pe procedeele de obținere și mecanismele de interacțiune. Principalele obiective ale cercetării Echipei 12 constau ȋn ȋmbunătăţirea prelucrabilităţii şi ȋnlocuirea, pe cât posibil, a aditivilor toxici și a polimerilor sintetici cu materiale izolate din resurse naturale și regenerabile. In ultimii 10 de ani, ȋn cadrul unor proiecte naţionale şi europene (PC6, PC7 şi Orizont 2020), Echipa 12 a dobândit cunoştinţe şi a câştigat experienţă ȋn dezvoltarea unor tehnologii de obţinere a unor (nano)compozite, atât pe bază de polimeri sintetici (PP, PMMA, elastomer termoplastic, cauciuc siliconic) cu diferite (nano)umpluturi (nanosilicaţi naturali, cu morfologie lamelară sau tubulară, nanofire de silice, fibre naturale, nanosilice, metasilicat de calciu) cât şi pe bază de biopolimeri (biopoliamidă, poliesteri alifatici, colagen şi celuloză) cu diferiţi agenţi de ranforsare (structuri 2D grafenice şi nongrafenice, nanofibre de celuloză), implementate şi validate la nivel de TRL 5-TRL 9, pentru fabricarea de: • Componente auto de ȋnaltă calitate (bară paraşoc, formă de depozitare roată de rezervă, stâlp-B) • Ambalaje alimentare • Produse de uz veterinar • Produse biomedicale • Acoperiri de protecţie

Olympus BX53 System Microscope
Olympus BX53 System Microscope is ideal for advanced research. The instrument provides excellent brightness and allows for sharp imaging and has color rendering performance. It provides the following observation methods: -Brightfield -Darkfield -Phase Contrast -Fluorescence (Blue/Green Excitations) -Fluorescence (Ultraviolet Excitations) -Differential Interference Contrast -Polarized Light -Simple Polarized light
Dynamic Mechanical Analyzer DMA Q800
DMA is used to measure the mechanical properties of a wide range of materials. Many materials, including polymers, behave both like an elastic solid and a viscous fluid, thus the term viscoelastic. DMA measures the viscoelastic properties using either transient or dynamic oscillatory tests. Storage modulus (E’), the elastic component is related to the sample’s stiffness and Loss modulus (E”) the viscous component is related to the sample’s ability to dissipate mechanical energy through molecular motion. Tan δ is parameter that provides information on the relationship between the elastic and inelastic components.
Simultaneous DSC-TG Analyser coupled with Mass Spectrometer (SDT-MS) SDT Q600 / ThermoStar TM GSD 301 T
Simultaneous DSC-TGA SDT Q600 is an analysis instrument capable of performing both differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) at the same time. The SDT measures the heat flow and weight changes associated with transitions and reactions in materials over the temperature range ambient to 1500°C. The information provided differentiates endothermic and exothermic events which have no associated weight change (e.g., melting and crystallization) from those which involve a weight change (e.g., degradation). Modes of Operation: – Standard: Ramp / Isothermal – Stepwise Isothermal – Cyclic – Evolved Gas Analysis High Resolution SDT.
Thermogravimetric Analyzer TGA Q5000IR
The Thermogravimetric Analyzer measures the amount and rate of weight change in a material, either as a function of increasing temperature, or isothermally as a function of time, in a controlled atmosphere. It can be used to characterize any material that exhibits a weight change and to detect phase changes due to decomposition, oxidation, or dehydration. Modes of Operation: Standard TGA, Hi-Res TGA, Auto Stepwise TGA, Modulated TGA, Evolved Gas Analysis – EGA (TGA/MS and/or TGA/FTIR Operation).
Differential Scanning Calorimeter DSC Q2000
The Differential Scanning Calorimeter (DSC) determines the temperature and heat flow associated with material transitions as a function of time and temperature. It also provides quantitative and qualitative data on endothermic (heat absorption) and exothermic (heat evolution) processes of materials during physical transitions that are caused by phase changes, melting, oxidation, and other heat-related changes.
