The Mechanics of Reinforcement in Polymer-Based Nanocomposites

Although there has been a rapid growth of interest in polymer-based nanocomposites the mechanics of reinforcement in such materials is still not yet fully understood. It has been established by the authors that stress transfer from the matrix to the reinforcement in nanocomposites reinforced by graphene nanoplatelets (GNPs) can be followed from stress-induced Raman band shifts. A detailed study has been undertaken of the mechanisms of stress transfer in a range of polymeric matrices with very different levels of Young’s modulus, Em, reinforced by graphene nanoplatelets (GNPs). The matrix materials studies have been natural rubber (Em ~ 1MPa), thermoplastic elastomers (Em ~ 10-100 MPa) and polypropylene (Em ~ 1000 MPa). The microstructure of the nanocomposites has been fully characterised using a range of different advanced analytical techniques that include, Raman imaging, x-ray computer tomography (CT) scans and polarized Raman spectroscopy that give an unprecedented level of information upon their microstructures.

It is found that the addition of the GNPs leads to significant increases in stiffness in each polymer showing high levels of reinforcement are obtained. For each material the effective Young’s modulus of the graphene, Eeff, has been determine using the rule of mixtures and it has been found that this scales with the value of Em. Additionally the stress-induced Raman bands shifts show different levels of stress transfer from the polymer matrix to the GNPs which again scale with the Young's modulus of the matrix.

A unifying theory has been developed to predict the stiffness of the bulk nanocomposites from the mechanics of stress transfer from the matrix to the GNP reinforcement based upon these studies of deformation of the individual flakes. Excellent agreement has been found between the measured and predicted values of Eeff, and hence composite Young’s modulus for the bulk nanocomposites.

Learning from nature and based on lotus leaves and fish scale, we developed super-wettability system: superhydrophobic, superoleophobic, superhydrophilic, superoleophilic surfaces in air and superoleophobic, superareophobic, superoleophilic, superareophilic surfaces under water [1]. Further, we fabricated artificial materials with smart switchable super-wettability [2], i.e., nature-inspired binary cooperative complementary nanomaterials (BCCNMs) that consisting of two components with entirely opposite physiochemical properties at the nanoscale, are presented as a novel concept for the building of promising materials [3-4].

The smart super-wettability system has great applications in various fields, such as self-cleaning glasses, water/oil separation, anti-biofouling interfaces, and water collection system [5].

The concept of BCCNMs was further extended into 1D system. Energy conversion systems that based on artificial ion channels have been fabricated [6]. Also, we discovered the spider silk’s and cactus's amazing water collection and transportation capability [7], and based on these nature systems, artificial water collection fibers and oil/water separation system have been designed successfully [8].

Learning from nature, the constructed smart multiscale interfacial materials system not only has new applications, but also presents new knowledge: Super wettability based chemistry including basic chemical reactions, crystallization, nanofabrication arrays such as small molecule, polymer, nanoparticles, and so on [9].

Nanostructured Liquid-Crystalline Assemblies for Energy and Environmental Applications

Takashi KATO

The University of Tokyo, Japan

Functional liquid-crystalline (LC) materials have been developed for use as ion conductors[1-5], water treatment membranes[6], and templates for the formation of organic/inorganic composites[7]. Design of molecular shape, control of molecular interactions, and formation of nanostructures play crucial roles for the development of these functional materials.[1-6] The orientation control and switching of conductivities have been achieved for ionic liquid crystals.[2,3] These nanostructured assemblies ionic are also applied as electrolytes for lithium ion batteries.[4] Another approach using LC assemblies is to develop bio-inspired environmentally friendly composite materials based on oriented LC templates. Chiral LC materials act as templates for the crystallization of calcium carbonate, resulting in the formation of ordered environmentally benignant composite materials.[7] Calcium carbonate-based LC nanorods have been obtained.[8] Aligned solid thin-films consisting of the LC nanorods have been formed by orientation by mechanical sharing.

Self-healing, Damage Sensing, Actuating Magnet-Polymer Composites


Nanyang Technological University, Singapore

Magnet filler-polymer matrix composites (MagPol) are promising materials in which to incorporate multifunctionality, due to the flexibility in the choice of polymer matrix and magnetic fillers. The use of magnetic fillers has several advantages which include remote contactless heating and actuation, several actuation modes, high actuation strain and strain rate, self-sensing and quick response. We focuse on the development of a tri-functional composite capable of damage sensing, self healing and actuation.

In this work we develop magnetic composite films using magnetic particles embedded in commercially available thermoplastics. Damage is detected via visible color changes in the composite. This is achieved by the addition of mechanochromic dye to the film. Plastic deformation of the polymer results in a color change indicating the damage site. Healing of the damaged site can then commence by subjecting the film to an alternating magnetic field. Curie temperature controlled magnetic nanoparticles embedded in the film generate heat which facilitates chain mobility and healing via the reptation mechanism. Additionally, the presence of the magnetic particles enables the film to be influenced by an external magnetic field and thereby to actuate in both a static and dynamic manner. We have thus developed a low cost trifunctional magnet polymer composite capable of sensing, self healing and actuation. Applications of such a composite would include morphing aircraft wings, wind turbine blades, deployable space structures, structural health monitoring etc.

Inspired by nature, self-healing materials represent the forefront of recent developments in materials chemistry and engineering. Herein, fully biodegradable and light-healable materials were first prepared from synthetic poly (propylene carbonate) (PPC) and biobased cellulose nanocrystal(CNCs)via quaternary hydrogen bonding between urea isopyrimidone (UPy) units, among which UPy functionalized PPC were first prepared via living anionic polymerization between CO2 and propylene oxide (PO) initiated by UPy containing alcohol. These nanocomposites displayed significantly improved mechanical properties comparing to PPC, as well as self-healing ability in presence of ultraviolet radiation.
