A new report presents a promising application of polyurea nanofibers to enhance the anti-corrosion and wear resistance of epoxy resins.
Highly dispersed nanofibers with continuous strengthening interface can enhance the anticorrosion and wear resistance of traditional waterborne epoxy resin. Polyurea ~50 nm in diameter nanofibers were synthesised by addition polymerisation of methylene diphenyl diisocyanate and organic amine.
The impedance of as-prepared composite coatings was increased by almost four times, providing longer lasting protection even in harsh environments. Meanwhile, the polyurea with 0.25 wt% nanofibers can greatly improve the wear resistance of coating up to 73.2 %. The anti-wear capacity of composite coating is derived from the entangled polyurea nanofibers transmitting the force of the contact surface and dimensional resistance to prevent coating displacement.
The study was published in Progress in Organic Coatings, Volume 171, October 2022.

The microstructure of an organic coating affects the leaching of inhibitor pigment, and this microstructure can be altered by the addition of other pigments.
The network of cavities and voids formed upon dissolution and removal of the soluble pigment introduces transport paths, and consequently, facilitates the leaching of the main inhibitor pigment.
Adequate leaching of active inhibitor pigments in organic coatings is essential for corrosion protection that relies on active inhibition of the metallic substrate. Therefore, it is important to obtain a comprehensive understanding of the factors that influence leaching kinetics and mechanisms. In the present study, model organic coatings were formulated to investigate the influence of additional pigmentation (i.e. pigments other than the main inhibitor) on the leaching of species released from the main inhibitor pigment.
In a recent article, It was found that addition of soluble/sparingly soluble pigments to the organic coating resulted in increased leaching rate. This was attributed to the formation of clusters comprised of both the main inhibitor pigment and the additional pigment. The network of cavities and voids formed upon dissolution and removal of the soluble pigment introduces transport paths in the organic coating, and consequently, facilitates the leaching of the main inhibitor pigment.

The Engineering Council has announced the formal signing of new agreements with Spanish professional bodies Asociación de Ingenieros Profesionales de España (AIPE) and the Agency for Qualification of Professional Engineers (AQPE), which will facilitate the mobility and recognition of engineering professionals between the UK and Spain.
AIPE are based in Madrid and AQPE represents the Catalan region, based in Barcelona. Both AIPE and AQPE competence standards are based very closely on the Engineering Council’s UK Standard for Engineering Competence and Commitment (UK-SPEC) and their processes – including a professional review interview – are similar. Both organisations have had their standards in place for six years (with support from the Institution of Mechanical Engineers, IMechE) and award titles including Expert Professional Engineer and Senior Professional Engineer. Engineers registered with the Engineering Council, or certified by AIPE and AQPE are required to demonstrate they are maintaining and developing their professional competence through a process of Continuing Professional Development (CPD).
On 29th September the Science Council held its first ever policy conference entitled The Science Council Climate Conference – The UK Pathway to Net-Zero. The event brought together Science Council members and other organisations from across the science and engineering community to discuss how the UK can meet its targets for reducing emissions and reaching net-zero in the coming years.
The conference drew on the diverse expertise of member organisations, exploring in depth topics such as the challenges and opportunities in the food system, achieving net-zero in the steel industry and the role of hydrogen in balancing future supply and demand.
Speaking at the conference, Sir Patrick Vallance, Government Chief Scientific Adviser and National Technology Adviser, said: “Every year, we’re losing Arctic Sea ice and CO2 levels have dramatically increased since the industrial revolution. There are clearly unarguable changes that are occurring. Science and technology are undoubtedly central to what we need to do. We need to be focused on technologies that we can already see, technologies that we have already invented, and ask how do we work out which of those we can implement and scale.”
