1. Rheological and mechanical properties of systems containing nanocellulose
Abstract : Nanocellulose is a cellulose entity at the nanoscale. There are several different types of nanocellulose such as cellulose nanofibrils (CNF), which are long, somewhat flexible fibrils and cellulose nanocrystals (CNC), which are shorter and more rod-like particles. READ MORE

2. Mass Transport Through Polymer Films: The Importance of Interfaces and Compatibility
Abstract : Different types of barriers are used in packaging to keep and protect products from the surrounding environment and are often essential for storing and transportation. Today, many barriers are made of different types of polymers, but since most polymers do not exhibit desired barrier properties on their own, combinations must be used. READ MORE

3. Additive-Driven Improvements in Interfacial Properties and Processing of TMP-Polymer Composites
Abstract : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.

4. Melt Spun Electro-Conductive Polymer Composite Fibers
Abstract : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.

5. Water-assisted mixing and compression moulding of ethylene-acrylic acid copolymer reinforced with nano-cellulose
Abstract : The concerns regarding aspects of global warming, depleting oil resources, accumulation of plastics in landfills has served as motivation to move towards utilizing sustainable and renewable resources to fulfil our needs. In the present work, the reinforcing capabilities of cellulose nanofibrils (CNF) and modified/unmodified cellulose nanocrystals (CNC) based composites prepared through water-assisted mixing, drying and compression moulding was explored.
