Summary: The method of breath figure (BF) has attracted much attention due to its simplicity and adjustability for preparing ordered porous films. Polymers from biomass have received a lot of attention because of their advantages of low carbon, green, good biocompatibility, and easy modification. This article reviews the physicochemical modification of biomass-based polymers and the preparation of ordered porous films via BF. Future research could focus on the preparation of ordered, functional, and biocompatible porous films with smaller pore sizes for more applications in different fields.

Summary: Ordered porous polyimide films were fabricated from (AB)(m) type of diblock copolymer polyimide-b-polystyrene (PI-b-PS). Increasing the volume fraction of polystyrene (f (V)(PS)) can decrease the relative dielectric constants and water contact angles of the porous PI films. The porous PI films displayed excellent wettability and can be used as low-kappa materials. The solvent uptake of the porous PI films increased with increasing f (V)(PS), and a net-like morphology appeared at f (V)(PS) of 0.36.

Summary: A facile method is proposed to prepare all-brominated cesium lead bromide perovskite films, by pre-introducing an appropriate amount of cesium bromide in the first step. This method enables the formation of a single phase cesium lead bromide film with full coverage, requiring only one cesium bromide supplementation. The preparation time of cesium lead bromide films is significantly shortened, providing a practical approach for large-scale production.

Summary: Ordered nanoporous structures can be achieved through selective electrochemical etching, resulting in a 2.7 times increase in photocurrent for porous GaN compared to planar GaN. The enhanced photocatalytic performance is mainly due to the increased specific surface area and modulation of the electric fields of incident light in the porous structures.

Summary: This study demonstrates the morphology transition of amphiphilic block copolymer honeycomb-structured films from primary to hierarchical adsorption-type microporous domains. The characteristic parameters of these hierarchical films can be controlled by changing the length of segments or swelling conditions. The research also shows that amphiphilic BCP with low volume content of hydrophilic blocks can efficiently stabilize water droplets during the morphology transition. This BCP film has potential applications in wastewater treatment, novel optical devices, and size-selective separation.

Summary: Bamboo is expected to replace wood as a structural material due to its abundant resources and environmental friendliness. This study optimized natural bamboo as a high-performance structural material through a green and simple process of high temperature and pressurization-densification, resulting in densified bamboo with excellent physical properties. The tensile strength, tensile modulus, flexural strength, and flexural modulus of densified bamboo exceeded those of natural bamboo. Additionally, the densified bamboo showed good anti-rebound characteristics and exhibited high specific strength, making it a significant source of engineering structural materials.

Summary: In this study, a facile method to synthesize hierarchically porous boronic acid group-functionalized monoliths with optical activity was developed using crosslinking and polymerization-induced phase separation (CPIPS). The composition of the pre-polymerization solution was adjusted to control the permeability and macropore size of the porous structure. The hierarchically porous structure and large surface area were confirmed by microscopy and gas adsorption measurements. Furthermore, the boronic acid functional group was successfully introduced on the surface of the monoliths, allowing for interaction with cis-diol groups. The monoliths exhibited good optical activity, showing potential in the recognition, separation, and adsorption of compounds with chirality and cis-diol groups.

Summary: This study presents a new approach to synthesize porous cobalt manganate nanocubes as a sulfur carrier for lithium-sulfur batteries, which significantly improves the cycling performance and stability of the battery. The porous nanocubes provide abundant active sites for sulfur accommodation and trap polysulfides during cycling, while the polypyrrole coating enhances electrical conductivity and suppresses polysulfide shuttling.
