Special Issue Information

Dear Colleagues,

Controlling the porosity of polymers at all levels, from micro to macro pores, is becoming increasingly important. Applications of porous polymers, which are now found in numerous fields, e.g., separation, catalysis, gas and liquid storage, biomedical science, etc., are driving the research of this section of polymer science. Not only polymers with porosity, on one level, but polymer materials with bimodal or hierarchical pore size distribution are emerging and are now playing vital roles in specialized applications. Furthermore, polymers with tailored morphology and topology can contribute to optimized properties where apparently contradictory characteristics can be obtained. Another example of advanced porous polymers is adaptive porosity as a response to environmental change. Methods for the preparation of porous polymers include phase separation, block self-assembly, templating, various processing and a number of chemical methods, either during or post-polymerization.

This Special Issue of Polymers aims to present full research papers, communications, and review articles based on the latest advances in the synthesis, characterization, and applications of porous polymers. Fields that will be covered include, but are not limited to:

  • Porous polymer synthesis (macroporous, microporous, hierarchical porosity, bimodal porosity)
  • Advances in porosity characterization
  • Porous structure–property relationships
  • Porous polymeric monoliths and membranes
  • Porous polymer applications

Polymerization of high internal phase emulsions (polyHIPEs) is a well-established method for the production of high porosity foams. Researchers are often regulated to using a time-intensive trial and error approach to achieve target pore architectures. In this work, we performed a systematic study to identify the relative effects of common emulsion parameters on pore architecture (mixing speed, surfactant concentration, organic phase viscosity, molecular hydrophobicity). Across different macromer chemistries, the largest magnitude of change in pore size was observed across surfactant concentration (~6 fold, 5–20 wt%), whereas changing mixing speeds (~4 fold, 500–2000 RPM) displayed a reduced effect. Furthermore, it was observed that organic phase viscosity had a marked effect on pore size (~4 fold, 6–170 cP) with no clear trend observed with molecular hydrophobicity in this range (logP = 1.9–4.4). The efficacy of 1,4-butanedithiol as a reactive diluent was demonstrated and provides a means to reduce organic phase viscosity and increase pore size without affecting polymer fraction of the resulting foam. Overall, this systematic study of the microarchitectural effects of these macromers and processing variables provides a framework for the rational design of polyHIPE architectures that can be used to accelerate design and meet application needs across many sectors.
