“…S19) The uneven temperature distribution visibly shows the exceptional thermal insulation capabilities of Zr-DPA/EP. Comparison of this work with previously reported epoxycontaining composites (27,31,34,(36)(37)(38)(39)(40)(41) in terms of thermal conductivity further reveals the excellent thermal insulation of Zr-DPA/EP (table S3).…”

Metal-organic frameworks (MOFs) hold great promise for diverse applications when combined with polymers. However, a persistent challenge lies in the susceptibility of exposed MOF pores to molecule and polymer penetration, compromising the porosity and overall performance. Here, we design a molecular-caged MOF (MC-MOF) to achieve contracted window without sacrificing the MOF porosity by torsional conjugated ligands. These molecular cages effectively shield against the undesired molecule penetration during polymerization, thereby preserving the pristine porosity of MC-MOF and providing outstanding light and thermal management to the composites. The polymer containing 0.5 wt % MC-MOF achieves an 83% transmittance and an exceptional haze of 93% at 550 nanometers, coupled with remarkable thermal insulation. These MC-MOF/polymer composites offer the potential for more uniform daylighting and reduced energy consumption in sustainable buildings when compared to traditional glass materials. This work delivers a general method to uphold MOF porosity in polymers through molecular cage design, advancing MOF-polymer applications in energy and sustainability.

Transparent bamboo (TB) is a new type of biomass and light transmitting material with potential to serve as substitute for transparent wood. However, the potential of the bamboo structure in preparing transparent composites is underexplored. Inspired by the functional gradient structure of bamboo, a simple and efficient two‐step strategy to prepare TB with different transmittance levels, fiber textures, and colors is used. The performance of single‐ and multilayer TB with various fiber volume contents prepared using different lamination methods is evaluated. It is found that the optical and mechanical properties of TB differ with the fiber volume content and the lamination method used. TB composed of veneers with low fiber volume shows the highest light transmittance (44.6%), whereas TB composed of veneers with high fiber volume has the highest tensile strength (45.7 MPa). In terms of water resistance, cross lamination inhibits expansion in width (water absorption rate, 16.37–21.26%) and thickness (thickness swelling rate, 10.22–21.74%). The lamination structure and fiber volume content in the preparation of TB should be selected according to the specific application scenarios. The graded utilization of bamboo veneer with a fiber gradient can effectively realize the rational allocation of bamboo resources and promote sustainable development.
