Current Research

Layer-by-layer assembly of functional polymers 

        Electrostatic layer-by-layer (LbL) assembly technique is an approach for fabrication of polyelectrolyte multilayers (PEMs) on the solid substrates based on electrostatic interactions between oppositely charged polyelectrolytes. LbL technique has attracted extensive research interests and intensive attentions in the past decades, not only due to the feasibility for preparation and the robustness of the PEMs but also the abundance of assembled functianl blocks and the precise control over the molecular architecture and low cost. Functional multilayer films have been directly constructured through electrostatic assembly between various functional materials including inorganic nanoparticles, proteins, virus, DNA and polyelectrolyte. We utilize the excess charged groups and counterion snaturally presenting in PEMs to create functional film. Firstly metallic precursor ions can be incorporated into multilayer film via counterion exchange, and metal nanoparticels/polymer composites can be fabricated through subsequently in-situ reduction. It is possible to repeat the counterion exchange/in situ reduction cycle when the bonding sites to counterions were reproduced and the counterions were regenerated after the reduction of counterions. Therefore, the content and size of metallic nanoparticles in PEMs can be controlleded by varying the number of exchange/reduction cycles using the same counterions; and bimetallic nanoparticles with special structure and even multimetallic nanoparticles with onion-like multilayer structure can be synthesized through using the same counterions. These metallic nanoparticles may find application in the fields of catalysis and optical materials.

Smart Responsive Surface

One of the hot topics currently is about the self-assembly technology. Electrostatic self-assembly has shown notable advantages, not only due to the feasibility for preparation but also applied to substrates of any shape and size, among many methods to prepared functional films. We take the advantages of the universality of the PEMs and the ease of surface modification of the PEMs through counterion exchange at the surfaces, to realize rapid and reversible change of the surface wettability. When we expanded the method of the counterion exchange on the PEM surface to a micro-, nano-structured substrate that exhibits roughness on two different length scales, tunable surfaces with wettability that can be manipulated rapidly and reversibly from superhydrophilicity to superhydrophobicity is successfully fabricated. By controlling the ion-exchange kineics, on the same surface, completed erasable, rewritable gradient surfaces with reversibly wettability was conveniently achieved.

Surface roughness has been proved to be one of key factors in the surface wettability. Our research focus on two kinds of substrates with different surface topograhpy: The micro-nano-structured gold surface and substrate coated with submicrometer scale silica spheres. Both of them show the same superhydrophobicity but extremely different contact angle hysteresisaccording to “Lotus Effect” and “Rose Effect”.

The Novel Structures of Conjugated Polymer

Compare to their inorganic counterparts, conjugated polymers are lighter, cheaper, and solution processable, features offering potential advantage in large-area flexible organic optoelectronic devices. Poly(3-hexylthiophene) (P3HT) is one of most promising conjugated polymer candidates for semiconductor applications such as organic field-effect transistors and organic solar cells. To achieve desirable charge mobility in semicrystalline P3HT films, P3HT molecules must be assembled with a high degree of intrachain order. We have prepared a new kind of poly(3-hexylthiophene)(P3HT) nanowhiskers self-assembled in dilute solution. These nanowhiskers were tens of micrometers in length, ~30 nm in width, but only 1.6 nm in thickness, corresponding to single molecular layer of P3HT in the side-chain direction, i.e. those are P3HT monolayer nanowhiskers. Field-effect mobility of these nanowhiskers measured in network state was 0.91 (± 0.23) ×10-2 cm2V-1s-1. Our findings provide new insight into the self-assembly behavior of P3HT as well as new building blocks for optoelectronic devices. Recently, we have taken advantage of these P3HT monolayer nanowhiskers to investigate the adsorption of P3HT to substrates with different surface functionalities in order to better understand the interactions between the surface and the P3HT interfacial layer. Meanwhile, a quick approach to obtain these nanowhiskers and fundamental investigations of crystallization process are underway.
