11:15-12:00: Precise Targeting of Electrochromatic Properties of Nanomaterials On-Demand

Omowunmi "Wunmi" Sadik
Professor of Bioanalytical, Materials and Environmental Chemistry
Center for Advanced Sensors and Environmental Systems (CASE) & Department for Chemistry
State University of New York, Binghamton, USA

My laboratory at SUNY-Binghamton has discovered a new class of nanostructured, ϖ-conjugated, poly (amic) acid - PAA. The uniqueness of PAA lies in its excellent chromatic, electronic, biodegradable and mechanical properties. PAA membranes showed remarkable potential as sensors for engineered nanoparticles. This talk specifically focuses on our continued efforts - including exciting results - ultimately aimed at small molecule-driven molecular design and preparation of sustainable nanomaterials with precise targeting of electrochromatic properties on demand. The materials provide superior properties which can meet the requirements of society’s expectations for a safer environment and sustainable future.

Barbara Karn  

10:15-11:00: Sustainable Nanotechnology: Where did it come from, what is it and why an organization?

Dr Barbara Karn, PhD
Executive Director and Co-Founder, Sustainable Nanotechnology Organization (SNO),
2020 Pennsylvania Ave, NW
Washington DC, 20006
USA

This seminar will first present a history of the development of sustainable nanotechnology, mainly from a US perspective. Then, a brief discussion of sustainability itself will follow. The aspects of sustainability that nanotechnology can help implement will be presented, including the 3 legs of the sustainability tool and the systems that constitute global sustainability. The presentation will then make a case for a professional society to bring researchers, practitioners, and governance bodies together to promote sustainable nanotechnology.

11:15-12:00: A Holistic Approach to the Preparation of Composites of Polymers and Nanoparticles

Professor Tony McNally
Chair in Nanocomposites, Director of the International Institute for Nanocomposites Manufacturing (IINM)
International Institute for Nanocomposites Manufacturing, WMG, University of Warwick

There continues to be intense research interest in polymer nanocomposites (PCN’s) [1], but their potential has yet to be fully realised. Predominately, the practice has been to utilise solvent and/or sonication assisted mixing, in-situ polymerisation and template synthesis to prepare PCN’s. All approaches have significant limitations and are not readily scalable. The preparation of PCN’s using melt mixing, typically in twin-screw extruders, has also been reported. However, many studies utilise micro-extruders which operate with conical screws, the results from which are not scalable and those studies that have employed industrially relevant parallel twin-screw extruders have not been systematic. The tendency has been for researchers to mix the NP of interest into the polymer melt using whatever extruder/mixer available with no appreciation of the parameters that control NP dispersion and distribution in polymer melts. Moreover, many polymers are utilised in blends and localisation of NP’s in either phase has not been widely reported [2]. This presentation will highlight how a holistic approach is essential if the manufacture of PCN’s is to be sustainable and cost effective. Such an approach must include an understanding of the polymer-NP interface/interphase as well as primary and secondary processing [3-6].

13:00-13:45: Sustainable Nanotechnology - Polysaccharide nanocomposites

Dr Chaoying Wan
Assistant Professor in Nanocomposites
International Institute for Nanocomposites Manufacturing (IINM), WMG, University of Warwick

Polysaccharide and polysaccharide derivatives are naturally abundant, green and sustainable materials. The high chemical reactivity and stiffness provide them various opportunities in functional nanocomposites applications for biomedical devices, absorbents for waste water and packaging materials. Here we mainly discussed our recent research in graphene oxide modified polysaccharide (pullulan, chitosan and alginate) nanocomposites. The effects of graphene oxide on the mechanical, gas-permeability and biomedical activity were discussed. The resultant nanocomposties are targeting to tissue-scaffolds and food packaging.

13:45-14:30: Moving Sustainable Nanotechnology Forward

Nanomaterials and nano-enabled products (i.e. nanoproducts) are experiencing an impressive development nowadays and several applications are entering the market or are expected to do so in the near future. This requires appropriate robust and science based criteria and methodologies to evaluate and manage their sustainability. During this research project a comprehensive set of criteria for evaluating nanoproducts sustainability was developed. It is structured in six main areas: (i) economic performance; (ii) environmental impacts; (iii) environmental risk assessment; (iv) human health risk assessment; (v) social implications and (vi) technical performance. The reliability of the criteria in each area was verified in addition to their validity. Furthermore, the relative importance of the criteria was calculated as well as their correlations. On the whole, this study demonstrates that the survey is a powerful and effective research tool for the identification of research and policy priorities in area of sustainable nanotechnology. .
