The aim of the GreeNanoFilms project is to develop and apply ultra-high resolution nano-organized films by self-assembly of plant-based materials for next generation opto- and bio-electronics.

Carbohydrate biomass constitutes an abundant and renewable resource that is attracting growing interest as a biomaterial. Convincingly the use of different natural “elementary bricks”, from oligosaccharides to fibers found in biomass, when mimicking self-assembly as Nature does, is a promising field towards innovative nanostructured biomaterials, leading to eco-friendly manufacturing processes of various devices. Indeed, the self-assembly at the nanoscale level of plant-based materials, via an elegant bottom-up approach, allows reaching very high-resolution patterning (sub-10nm) never attained to date by petroleum-based molecules, thus providing them with novel properties.

GreeNanoFilms aims to use carbohydrates as “elementary bricks” (glycopolymers, cellulose nanocrystals and nanofibers) for the conception of ultra-high resolution nanostructured technical films to be used in various markets, from large volume sectors, such as

(i) high-added value transparent flexible substrate for printed electronic applications, (ii) thin films for high-efficiency organic photovoltaic,

to growing markets, such as (iii) next generation nanolithography and (iv) high-sensitivity SERS biosensors.

GreeNanoFilms main impacts are the implementation of a new generation of ultra-nanostructured carbohydrate-materials that will play a prominent role in the achievement of the sustainability improvement of various opto- and bio-electronic sectors. The prospective environmental impacts and benefits of new green processes, eco-efficient nanomaterials and nanoproducts will be quantified with Life Cycle Assessment, risk assessment and validation of the industrial feasibility, including economic evaluation of the products.

The objectives of this project are divided in 9 WPs where

WP1: Project management deals with the coordination and the management of GreeNanoFilms.

WP2: Self-assembly focuses on the design of bio-sourced block copolymer systems (BCP) to be used as active thin films for the identified and listed target applications (next generation nanolithography, OPV and Biosensors).

WP3: CNF film processing: Production of cellulose nanofibrils (enzyme assisted CNF and TEMPO-oxidized CNF from birch kraft pulp) using fibrillation procedures involving chemical and mechanical treatments and the quality control of all materials involved (pulp, fibrils and films).

WP4: Transparent Nanocellulose Technical Films: process and analyze R2R NIL patterned CNF films without CNC coatings and (2) implement CNC production further and characterize the produced CNC.

WP5: Opto-electronic device: Realize polymer/fullerene disordered bulk hetero-junction (BHJ) solar cells on cellulose nano-fibre film (CNF) at lab-scale (few mm² up to 5x5cm²) including: the Design BHJ solar cell architecture (structure, materials and pattern)

WP6: Next-generation high-resolution nanolithography, high-sensitivity SERS biosensors

One of the main objectives during the first half period of work is to develop technology to achieve a long-range periodic ordering of domains in directed self-assembly (DSA) process of MH-b-PS block-copolymers (BCP). Another objective is to optimize process conditions to selectively remove one of the components (e.g. by reactive ion etching in oxygen or other process).

WP7: Demonstration: The objective of this WP is to produce and assemble prototype products on a larger scale to demonstrate the developed technologies.

WP8: Sustainability, LCA & Risk assessment: It deals with the sustainability, life cycle assessment (LCA) and risk assessment with regard to the materials, processes and applications developed in the project.

WP9: Dissemination & Exploitation: The objectives of the WP 9 are devoted to the communication, dissemination and exploitation activities
