Supramolecular impactmechanism of polycarboxylate superplasticizers on controlled hardening building nanocomposites

Thin Films of Supramolecular Nanocomposites

Assessment of the interaction of polycarboxylate superplasticizers in hydrated lime pastes modified with nanosilica or metakaolin as pozzolanic reactives

Two polycarboxylate ether copolymers were assessed as superplasticizers (SPs) for hydrated lime pastes modified with two reactive compounds, nanosilica (NS) and ceramic metakaolin (MK). Characterization of the molecular structure of the SPs by Size Exclusion Chromatography, XRD, FTIR and MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time-of-Flight) mass spectrometry was performed. The ...

Nanostructures on graphene using supramolecule and supramolecular nanocomposites.

Nanopatterning and functionalizing of graphene is often required to tune or enhance its unique physical properties. However, complex processes are needed to overcome the chemical incompatibilities between the patterning template, the functional small molecules or nanoparticles, and the underlying graphene. We present a block copolymer (BCP)-based supramolecular thin film as a versatile platform...

High-strength, healable, supramolecular polymer nanocomposites.

A supramolecular polymer blend, formed via π-π interactions between a π-electron rich pyrenyl end-capped oligomer and a chain-folding oligomer containing pairs of π-electron poor naphthalene-diimide (NDI) units, has been reinforced with cellulose nanocrystals (CNCs) to afford a healable nanocomposite material. Nanocomposites with varying weight percentage of CNCs (from 1.25 to 20.0 wt %) within...
