“…The final water contact angle values were similar for the both systems. This was possibly due to the faster degradation of the epoxy‐cured PMAD than that of the alcohol‐cured one due to the ozonolysis of aromatic moieties included in the epoxy‐cured PMAD . Furthermore, the difference in the chemical structure of the crosslinking points should also be considered, i.e.…”

Crosslinking and de-crosslinking reactions of an alternating copolymer of maleic anhydride (MAn) and 2,4-dimethyl-1,3-pentadiene (DMPD) by thermal curing with polyfunctional alcohols as the crosslinkers and subsequent ozone degradation are reported in this article. The ring-opening reaction of an anhydride group by polyfunctional alcohols produces network polymers with an ester linkage. The rate of crosslinking reaction depends on the curing conditions, i.e. the structure of the used alcohols and the curing temperature and time. The crosslinking density of the alcohol-cured copolymers is low due to a slow reaction between the anhydride and hydroxy groups, being different from the corresponding epoxy-cured copolymer with a dense network structure reported in a previous article. The insoluble resins are readily de-crosslinked and solubilized by ozone degradation. The polymer surface modification by ozone is also investigated.

“…In this paper we present UV/ozone (UVO) pre-treatment as a straightforward method to activate SU-8 surfaces [17][18][19] and control chemisorption of molecules [3,4]. Because UVO leads to a milder surface oxidation than argon or oxygen plasma treatment, the SU-8 surface roughness is not affected by UVO exposition.…”

SU-8 photoresist polymer is widely used in the fabrication of microdevices. However, for biological applications, the problem of efficiently modifying SU-8 surfaces without perturbing roughness has not been successfully resolved. We present UV/ozone (UVO) surface pre-treatment as an effective method to increase the hydrophilicity of SU-8 films without affecting surface roughness, thus improving specific covalent binding of bio-molecules. We demonstrate that 30 s UVO treatment suffices to create carboxyl groups at the surface that can then be used for high density binding of molecules via amide bond formation. We further demonstrate that a two-step surface modification where the surface is first protected with an ethylene glycol monolayer leads to an increase in binding specificity. Finally, to illustrate the controlled binding and accessibility of immobilized molecules, we show three cycles of reversible interactions between anti-tamra antibody and tamra-cadaverine immobilized on the surface of SU-8.

“…Indeed, additives are often included in formulations with the express intent that the additive should migrate to the coating/paint surface so at to perform its specified function (or functions). Such functions may include levelling, [5] anti-cratering, [6] enhancing substrate wetting and improving flow.…”
