The journal “Materials” is preparing a Special Issue titled “New Trends in Polymeric Foams”. In this Special Issue, recent research on advanced polymeric foams is considered.
Polymeric foams—also known as cellular polymers—are materials of great interest that can be found everywhere in our present world. Their particular structure gives them unique properties that allow a broadening of the range of properties of their solid counterparts. The applications of these foamed materials are thus very extensive. They are of special interest in sectors like construction, automotive, aeronautics, packaging and protection, biotechnology, energy management, etc. Currently, more than 10% of the polymers produced around the world are used to produce polymeric foams.
The needs of today’s society, in which both reducing the energy consumption and the amount of raw materials and using environmentally-friendly technologies are a must, make necessary the development of advanced foaming technologies and cellular materials with improved properties. In this way, current polymer foams could be substituted by materials with improved performance, the applications of traditional foamed polymers could be extended, and finally, solid plastics could be replaced by foamed ones.
In the last few years, special importance has been given to reducing the cell size up to the nanometre range, giving rise to nanocellular polymers, to understand the complex mechanisms underlying the formation of cellular materials, to develop improved foaming technologies, and to obtain improved properties by tuning the formulations used to produce these materials.
Research on nanocellular polymers has increased significantly due to their potential properties. These novel materials could have better mechanical properties than conventional foams, thermal conductivities well below those presented by current insulation materials, they can be transparent, and they have enhanced dielectric properties. As a consequence, the door is opened to a significant number of new applications, such as super thermal insulation, filtering, sensing, catalysis, etc.
On the other hand, understanding the mechanisms taking place during the foaming process is a factor of major importance in establishing a relationship between cellular structure, properties, and applications. The use of conventional and non-conventional experimental techniques to analyse the foamability of different complex polymeric formulations can be helpful to design new materials with advanced properties. Thermal and rheological techniques, visualization techniques to evaluate nucleation and growth during injection moulding, in-situ rheological measurements during extrusion, X-ray radioscopy and tomography, among others, are examples of these non-conventional techniques.
In addition, the development and/or the improvement of the technologies to produce cellular polymers and the development of improved formulations are hot topics in the field, being in many cases the results of this research of direct application in the industry.
This Special Issue considers recent research on advanced polymeric foams. Of special interest are the research topics focused on developing new formulations and technologies to produce improved cellular materials, as well as those related to the analysis of the foaming mechanisms by using different conventional and non-conventional experimental techniques.
Research in these particular fields is required which considers the needs of today’s society, including the reduction of energy consumption and the amount of raw materials as well as the development of environmentally-friendly technologies.
It is our pleasure to invite you to submit a manuscript for this Special Issue.
