Grafted Polymers and Nanostructures on Surfaces

Smart coatings can be achieved by fine tuning nanostructures in ultrathin films.The use of grafted polymers and particles on surfaces enable the modification and formation of robust coatings which can lead to very interesting stimuli-responsive properties. Polymer brush formation can involve surface initiated polymerization (SIP) or by grafting preformed polymers (but with low density). Another method can involve the application of colloidal particles to form uniform layers on surfaces or the application of lithographic and non-lithographic methods (can be expensive).

Milling: vertical or horizontal?

Dispersing fillers and pigments is one of the most important steps during paint manufacturing. This fundamental step is often understood as art more than as a scientific technology meaning the beaking down of pigment agglomerates and their distribution in a liquid phase. Dispersion is among other techniques performed by using attrition mills, which can be vertical or horizontal. Which of these designs is the best divides opinions.

Smart coatings – truly stretchable

Picking up on our latest blog entry, I have just come back from the European Coatings Conference "Smart coatings” with the conviction that the term "smart” is truly stretchable if not controversial.

Smart is too hip and trendy

Today nearly no coating exists on the market the word smart is not used for. No matter what kind of nanomaterial has found its way into the product, you always have one more feature than the "old school” requirements. For example corrosion protection, aesthetics and bending skills are usual demands, nothing special. These minimum requirements have to fit and are just compared to elderly products. It seems to me that the industry is tired of speaking about these skills.

Analysing sustainability

No doubt - sustainability is on everybody's lips these days. But how to measure it reliable? Of course there are methods available such as life cycle assesment (LCA), carbon footprint (CFP) and eco-indication 99 method. However, up to now no agreement is made within the coatings industry which of these methods is the best in terms of feasability and comparability. Jan Besamusca, DSM suggests to measure the CFP and recalulated it to the solid product.

Nanomaterials and the end-of-life question

Nanotechnology and novel materials are innovation drivers when it comes to the development of clean and efficient technologies. An industry dialogue recently held by the German Federal Ministry of Education and Research gathered material and nanotechnology R&D experts and environmental professionals who focused on opportunities and challenges of nanomaterials for environmental technologies.

Less raw materials, higher prices and no end in sight

Delivery difficulties for and disproportional price increases of many raw materials are challenging the coatings industry. According to national and international associations prices for certain raw materials have increased drastically – in the worst case by up to 50 %.

DOE- useful or not?

Design of experiments (DOE) is quite often a topic of hot debate in discussions with coatings experts. In my opinion DOE is good tool to reduce the time required to develop novel coating systems. On the other hand I am doubting that this tool is really used by paint manufacturers, especially by SMEs. Most of the formulators believe that personal experience in coatings development is more important than anything else. Those people do not believe in statistics and software. What is your preference?

Green adhesives

Two weeks ago I attended the FEICA European Adhesives & Sealants Conference in Helsinki, Finland. The program was mainly focused on market topics. The good news is that markets for adhesives are growing globally next year. However, I was specially interested in technical trends in adhesive formulation. Apparently, many people are working on bio-based and degradable systems. Experts I talked to expect these products to be available on the market in 1 to 2 years. However, some interessting research results are already available.

News about carbon nanotubes

A while ago I wrote about carbon nanotubes (CNTs) in this blog (see my entry of 26 January, 2010). Enthusiastically I recorded that CNTs have the potential to generate completely new materials and products with characteristics and combinations thereof that were not feasible with previous technologies. In the meantime a lot of new findings have been published, basically agreeing to this assessment.
