I am devoted to Supramolecular Chemistry and Nanotechnology. My research is focused on combining both topics to design and prepare new materials inspired by Nature. I prepare cyclodextrin polymers, either crosslinked or lineal, to caps noble metal or semiconductor nanoparticles creating a synergistic effect between the receptor/recognizing capabilities of cyclodextrin and the intrinsic properties of nanoparticles. Nanoparticles are also chemically or physically modified on its surface to
achieve new physical properties (hydrophobic/hydrophilic compromise, shape, luminescent, among others).
My latest project (Fondecyt-11190555) aims to prepare supramolecular copolymer-binders based on adamantane and cyclodextrin host-guest interaction to assemble silicon anodes for Li-Ion batteries. Silicon anodes show a much higher gravimetric capacity than the actual carbon anodes but suffer from capacity fading due to their volume expansion (X300) upon lithiation and de-lithiation process. The reversible supramolecular interactions of binders are desirable for the healing of silicon particles during the battery cycling life.
Additionally, we prepare superhydrophobic composite membranes for desalinization of seawater, using membrane distillation technology. To achieve superhydrophobic membranes we used surface-modified nanoparticles (alkyl fluorinated-capped CuO or silica nanoparticles) to change the membrane properties by decreasing the surface energy.

Investigaciones :
As part of the Fondecyt 11190555 project, we are preparing silicon anodes using linear copolymers of polyacrylic acid with β-cyclodextrin and adamantane as binding agents. We study the correlation of polymers structure/composition with the self-healing properties on silicon. Our maxima goal is to prepare stable silicon anodes with long cycling life (>500 cyles) and with gravimetric capacity close to the theoretical. The research includes:
i) Designing and preparing vinyl monomers of β-cyclodextrin and adamantane, co-polymerizing them with acrylic acid, and characterizing the resulting products.
ii) Preparing silicon anodes using the synthesized polymers as binding agents
iii) Assembling half-cells, performing electrochemical characterization, and assessing cycling performance (gravimetric capacity, coulombic efficiency, and charge/discharge rate capability).
