durchlässigere

Durchlässigere is the comparative form of the German adjective durchlässig, meaning more permeable or more transmissive. It is used attributively before a noun and agrees with the noun in gender, number, and case (for example: eine durchlässigere Membran, ein durchlässigerer Filter, das durchlässigere Material). The stem combines the prefix durch- (through) with the notion of letting substances or signals pass.

In usage, durchlässigere is common in natural sciences and engineering to compare materials, membranes, soils, or tissues by their ability to allow the passage of liquids, gases, or solutes. In biology, eine durchlässigere Zellmembran describes a membrane with higher permeability. In geology and hydrology, soil or rock layers can be described as durchlässiger if they permit faster groundwater movement. In filtration and chemical engineering, researchers seek durchlässigere Filtermedien to increase throughput or diffusion rates, while balancing permeability with selectivity.

The term can also be used metaphorically to describe openness or accessibility, for example when discussing institutions, processes, or communications that are more durchlässig for information, people, or ideas. In these contexts, the nuance extends beyond physical permeability to include ease of exchange and integration.

Related terms include Durchlässigkeit, the noun for permeability, and Permeabilität, used in technical disciplines to denote the measurable ability of a material to transmit fluids or gases.
