Sustainable transparent bamboo/W-VO2 composites for solar modulation and energy-efficient buildings
Bibliographic record
Abstract
Energy-efficient buildings require sustainable materials that combine structural performance with advanced optical and thermal functionalities to minimize energy consumption and greenhouse gas emissions. Here, we reported a new strategy to develop biodegradable transparent bamboo with a dense and ordered structure, achieved through selective delignification followed by directional pressing to align cellulose nanofibrils. This process yielded large-scale transparent bamboo with remarkable mechanical strength, 78% optical transparency in the visible spectrum, and a high haze (> 90%) that ensured uniform daylight distribution and reduced reliance on artificial lighting. To further impart dynamic solar modulation, a thin polylactic acid film containing tungsten-doped vanadium dioxide (W-VO 2 ) nanoparticles was integrated onto the transparent bamboo substrate. The resulting thermochromic bamboo exhibited a solar modulation ability of 9.7% along with effective thermal regulation that lowered indoor heating loads in hot regions. By synergizing biodegradability, mechanical robustness, and active photothermal control, this transparent bamboo/W-VO 2 composite offered a sustainable and high-performance alternative to conventional glass, holding great promise for energy-efficient building applications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
