“…Other methods to generate this extra porosity include leachable additives such as sucrose, polyvinyl pyrrolidone, sodium diphenyl ether disulphonate and pH dependent soluble polymer latex. 30 Future work includes optimization of latex dispersion formulation and the sintering process to fabricate an engineered stamp with sufficient gas permeability that will not trap air bubbles in the photopolymer during the roll-to-roll imprint process and will have a life of $1000 impressions. The testing to achieve this includes porosity and gas permeability characterization followed by roll-to-roll imprint life-testing of the stamp.…”
