A novel ultra-violet assisted anisotropic etching of plastic to realize micro-gears
(Elsevier: Sensors and Actuators A: Physical, 2004-09-21)An ultraviolet assisted chemical etching of plastic is reported in which the etching of PET substrates is anisotropic in the direction of light illumination. A strong solvent as di-methyl-formamide (DMF) is exploited to ... -
Surface modification of poly(biphenyl dianhydride-para-phenylene diamine) (BPDA-PDA) polyimide by UV photo-oxidation
(Springer-Verlag: Journal of Adhesion Science and Technology, 2006-03)Poly(biphenyl dianhydride-para-phenylene diamine) (BPDA-PDA, Upilex-S) polyimide (PI), was exposed to 185 and 254 nm UV radiation in the presence of oxygen at atmospheric pressure. SEM micrographs revealed only a small ...
