G12: Polymeric composites and nanocomposites
The Research Activity of Team 12 – Polymer Composites and Nanocomposites is focused on the development of multifunctional polymer composites and nanocomposites based on synthetic and/or natural polymers and various synthetic and/or natural micro/nano fillers, with low impact on the environment or biodegradable and with improved specific properties, imposed by different applications in industry (automotive and packaging), construction, agriculture and biomedicine. Consequently, the research directions considered are focused, on the one hand, on the characterization, physical or chemical modification and processing of both the components and the resulting (nano)composites, and on the other hand, on the processes for obtaining and interaction mechanisms. The main objectives of Team 12's research are to improve processability and replace, as far as possible, toxic additives and synthetic polymers with materials isolated from natural and renewable resources. In the last 10 years, within national and European projects (FP6, FP7 and Horizon 2020), Team 12 has gained knowledge and experience in developing technologies for obtaining (nano)composites, both based on synthetic polymers (PP, PMMA, thermoplastic elastomer, silicone rubber) with different (nano)fillers (natural nanosilicates, with lamellar or tubular morphology, silica nanowires, natural fibres, nanosilica, calcium metasilicate) as well as based on biopolymers (bio-polyamide, aliphatic polyesters, collagen and cellulose) with different reinforcing agents (graphene and non-graphene 2D structures, cellulose nanofibers), implemented and validated to TRL 5-TRL 9, for the manufacture of: • High quality automotive components (bumper, spare wheel well, B-pillar) • Food packaging • Biomedical products • Protective coatings
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.
