Macroporous gels with huge cavities and partition walls result from controlled microsyneresis during gelation. In this report we show that the microsyneresis process can be further controlled: it is possible to orient the partition walls of macropores by the use of an electric field throughout polymerization. Our oriented macroporous polyacrylamide gels offer a specific structure: a set of parallel channels of about 2 μm inner diameter, with polyacrylamide walls including acidic groups linked to the aggregated matter.
