Luminescent gels for energy applications This research activity was funded by European Commission as part of the Framework 7 integrated

project EPHOCELL -“Smart light collecting system for the efficiency enhancement of solar cells”, grant

agreement No 227127 (2009- 2013)

The main objective is focused on

preparation and characterization

of gels, based on low and high

molecular weight gelators, in

which organic molecules and/or

organo-metallic complexes are

embedded..

The research activity aims to

probe the effectiveness of DS and

UC mechanisms in gels with the

objective to develop new media for

DS and UC and to give rise, in the

long term, to a new generation of

luminescent solar concentrators

flexible and adaptable to several

geometries.

M. Avella, M. Cocca, M. L. Di Lorenzo, G. Gentile

An increase in the energy conversion efficiency of PV devices

could be obtained through a process of energy transfers

supported by adaptable molecular systems:

1) down-shifter (DS) – antenna molecules able to absorb UV

photons and to transfer the absorbed energy to an emitter,

which emits a photon in the absorption band of the photovoltaic

material.

2) up-converter (UC) - sensitizer molecules able to absorb IR

photons and to emit the absorbed energy in the absorption

band of the photovoltaic system.

DS activity: red emittion of 12-HSA gel with Eu(tta)3phen

complex exposed to UV light (l = 360 nm).

UC activity: green to blue conversion in

12HSA gels containig the couple S/E

palladium porphyrin (PdOEP)/Perylene

Selective localization of MWCNT

in microstructured composites

PS/PLA co-continuous blend with CNTs

Electrical resistivity

V. Ambrogi, C. Carfagna, P. Cerruti, G. Gentile, G. Nasti

A masterbatch of PS with 2wt% of MWCNT was prepared and then melt mixed

with different amounts of PLA. This two-step process led to a double percolated

morphology (i.e PS percolates in PLA phase, and MWCNTs percolate in PS phase).

SEM micrographs clearly indicated formation of bicontinuous morphology, while

TEM images evidenced high selectivity for MWCNT localization in the system. The

double percolation led to a very low electrical percolation threshold of about 0.15

v% MWCNT content on the total volume.

Phenol adsorption increases with GNP or MWCNT

Hyper-crosslinked resins (HCLR) are high surface area polymers based on the post

crosslinking of “gel-type” resins, usually realized by suspension polymerization.

The objective of this activity is the realization of HCLR containing carbon nanofillers, such as

plain or modified MWCNT or GNP, in order to modulate the specific surface area, the specific

pore volume, the pore distribution and the adsorption properties of the material.

RESULTS:

A new synthetic process for the

gel-type precursors was set up,

based on the bulk polymerization

of the starting monomers. This

allowed to easily embed MWCNT

or GNP within the HCLR

Si realizzano attraverso la combinazione/integrazione di diverse tecniche di espansione (foaming diretto, sintesi in situ di nano-porosità (aerogel), gas foaming, chemical e physical foaming) con la combinazione di materiali differenti (polimeri organici sintetici, naturali ed inorganici) che interagiscono con meccanismi chimico-fisici che agiscono su scale differenti: da quell’atomica a quella macroscopica.

L’architettura porosa può essere distinta sulla base della matrice di partenza: Schiume poliuretaniche: compositi e/o ibridi Schiume di origine naturale (Proteine vegetali o animali, polisaccaridi) Ceramici espansi compositi o ibridi (geopolimeri, diatomite, silico-aluminati, cementi)

Multifunctional Thermosets Self Healing Epoxy

The activities were performed in the framework of the FP7 European Project “ALAMSA ”

A Life-cycle Autonomus Modular System for Aircraft Material State Evaluation and Restoring System (ALAMSA)”

Epoxy resin based on Diels–Alder (D-

A) adducts has been synthesized and

crosslinked with amine curing agent

for the preparation of mendable

material.

The cured resin can heal multiple

time upon heat trigger.

Diels–Alder epoxies are miscible with

conventional epoxy and curing

agents. Their composition enables

the use of processing technologies

used for composites manufacturing,

like prepregging or liquid infusion of

dry fibers.

Composite in Fire: experimental and modelling

Fire resistance and Fire Reaction of composite elements surely stand up as fundamental issue for many

industrial sector. Enhanced fire performance could be achieved and modelling technique employed to prevent,

control and manage fire scenario.

Aeronautical Composites: engine tail fire event

Engine tail pipe fire event: qualification procedure

Tested stiffened panel

The wider use of composite materials for primary structures

pose the problem of their behavior when exposed accidentally

to a local overheating deriving from events like fire.

Overheating means that the structure is submitted to a

temperature higher than the design maximum service

temperature, generally 80°C.
