About

Materials scientist &
surface engineer

Prof. Mohammed Es-Souni is an Honorary Member of Kiel University of Applied Sciences and founder of IMST — Institute for Materials & Surface Technology. Over 35 years, his research has consistently delivered functional coating technologies that solve real-world problems in medicine, industry, and energy.

His work centres on two commercially impactful pillars: release-free antibiofouling and scratch-resistant coatings for medical devices, contact lenses, implants, and industrial surfaces; and electrocatalytic thin-film coatings for green hydrogen production alongside nanostructured electrochemical energy storage systems.

All coating technologies are developed using environmentally sustainable methods — photografting, sol-gel deposition, and electrochemical processing — enabling scale-up from laboratory to industrial production without hazardous processing routes.

His research has been funded by the DFG, German Federal Ministries, and the European Union, with a cumulative portfolio exceeding €15 million. Five technology transfer awards recognise the consistent translation of research into industrial value.

Technology Pillar I

Antibiofouling &
Scratch-Resistant Surfaces

Patented release-free antibiofouling and scratch-resistant surface coatings — no biocides, no leachable agents. Photografted polymer brushes on porous oxide scaffolds deliver simultaneous protein resistance and mechanical durability. Proven for medical devices, RGP contact lenses, implants, optics, and membranes. Available for licensing and co-development.

◎

Photografted Polymer Brush Systems

UV-initiated photografting of PEG, pSBMA, and related antifouling polymer chains directly onto substrate surfaces including porous alumina, metals, and polymers. Chemically anchored brushes resist protein adsorption and bacterial adhesion without releasing agents.

⬡

Porous Oxide / Polymer Brush Composites

Pore walls of anodized alumina and other porous oxide supports are functionalized with photografted antifouling brushes. This architecture combines mechanical robustness of the oxide scaffold with the antifouling chemistry of the brush — enabling scratch-resistant, non-fouling surfaces.

◈

Oxide-Polymer Nanocomposite Coatings

Inorganic-organic hybrid coatings combining metal oxide nanoparticles (TiO₂, SiO₂, Al₂O₃) with photografted antifouling polymer matrices. The hard oxide phase provides mechanical reinforcement and scratch resistance while the polymer brush imparts protein repellency — a superior architecture to purely organic multilayer systems.

01
Contact Lens Coatings (Patented)
Antifouling and wettability-enhancing coatings for rigid gas-permeable (RGP) contact lenses. Patented process (DE102018127812B4, granted 2020) providing long-term protein resistance and improved wearer comfort.
02
Medical Implant Surfaces (Patented)
Antibacterial and anti-adhesive coatings for medical implants (DE102018115709B4, granted 2020). NiTi shape memory alloy surfaces modified with photografted polymer brushes for smart implant applications.
03
Transparent Scratch-Resistant Antifouling (Patented)
Porous oxide-polymer nanocomposite architecture underpins the European patent (EP 18703549.8, granted 2022) for a transparent, scratch-resistant antifouling coating. The oxide scaffold provides hardness and optical transparency while the polymer brush prevents biofouling — validated for sensor covers, optics, and precision glass surfaces.
04
Membranes, Polymers & Silicones
Surface treatment of polymer nets, membranes, and silicone substrates for antifouling and hydrophilic performance. Suitable for filtration, microfluidics, and medical device housings via scalable photografting processes.
Technology Pillar II

Electrocatalytic Coatings
for Green Hydrogen

Nanostructured thin-film electrocatalysts for the hydrogen evolution reaction (HER) — TiN films with engineered oxygen defects, Au-nanorod-supported Pd/Pt catalysts, and porous PtPd alloy nanotube coatings. Outstanding HER performance with minimal precious metal loading. Scalable deposition processes for green hydrogen production electrodes. Validated in Nanomaterials, Catalysis Science & Technology.

⬡

TiN-Based Electrocatalyst Films

Thin films of titanium nitride (TiN) with engineered oxygen defects act as robust, cost-effective HER electrocatalysts with outstanding performance. The defect engineering strategy tunes electronic structure and active site density without relying on platinum-group metals. Validated in Nanomaterials 2024.

◈

Nanorod-Supported Pd & Pt Catalysts

Au-nanorod arrays used as high-surface-area supports for Pd and Pt nanocatalysts deposited at ultra-low loading. Systematic study (Nanomaterials 2023) demonstrated Pd outperforms Pt mass-for-mass on Au-NR supports — directly informing cost-reduction strategies for green hydrogen electrolysers.

◉

Porous PtPd Alloy Nanotube Coatings

Template-derived porous PtPd alloy nanotubes on substrate surfaces combine maximised active surface area with minimal Pt content. Demonstrated high-performance HER electrocatalysis with low Pt loading (Catalysis Science & Technology 2019) — a viable path to affordable water-splitting electrodes.

01
Sonochemical Nanoparticle Processing on TiN Substrates
Noble metal nanoparticles and nanoalloys synthesised directly on nanocarbon and TiN substrates from aqueous solution via sonochemistry — a green, one-step route eliminating surfactants and organic solvents. Enables electrode coatings with atomically dispersed catalyst phases (Ultrasonics Sonochemistry 2018; Micromachines 2023).
02
Nanocarbon & Carbon-CNT Composite Electrodes
Meso-macroporous graphite thin films and carbon-CNT nanocomposites processed via a novel on-substrate route provide high-surface-area, corrosion-resistant electrode supports. Modified nanocarbon surfaces with enhanced double-layer capacitance serve both as HER catalyst supports and as energy storage electrodes (Carbon 2017; RSC Advances 2014–2015).
03
Nanostructured Supercapacitor Electrodes
NiO nanostructures and Ni(OH)₂ nanolamellae electrode films deliver high specific capacitance for electrochemical energy storage — directly complementary to intermittent hydrogen production from renewable sources (Nanoscale Research Letters 2013; Micromachines 2023).
04
Piezo- & Pyroelectric Harvesting (Background Capability)
Established competence in piezoelectric (PZT, PVDF-TrFE) and pyroelectric (PMN-PT, PIN-PMN-PT) thin films for mechanical and thermal energy conversion. Available as a secondary technology stream for hybrid energy systems integrating harvesting with electrochemical storage or hydrogen production.
