{"doi":"10.1002/marc.202000290","title":"A Phase‐Changing Polymer Film for Broadband Smart Window Applications","abstract":"Abstract Smart windows (SWs) with tunable opacity are sought to regulate solar‐irradiation and privacy protection. A new smart window material based on a phase‐changing polymer that can be reversibly switched between a semicrystalline, opaque state and an amorphous, transparent state is introduced. The polymer film is a network of the phase‐changing poly(stearyl acrylate) crosslinked with a poly(ethylene oxide) oligomer. The two constituent polymers show strong phase separation. The transmission switching of the resulting copolymer film is resulted from the combination of three different mechanisms: reversible phase changing of the poly(stearyl acrylate) component, phase separation between the two distinct constituent polymers, and a large change of refractive index of the phase‐changing polymer during the amorphous‐to‐semicrystalline transition. The opaqueness switching can be reversed and repeated for more than 500 cycles of heating and cooling. A silver nanowire (AgNW)‐based transparent heater is combined with the SW film to control the semicrystalline‐to‐amorphous phase transition. The resulting smart window exhibits a high infrared transmittance modulation (Δ T IR ) of 80.4% and solar transmittance modulation (Δ T solar ) of 70.2%, which significantly outperform existing thermochromic smart windows.","journal":"Macromolecular Rapid Communications","year":2020,"id":77101,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":20,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9567,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":401944,"name":"Fangyi Guan","orcid":"0009-0006-8503-6740","position":1,"is_corresponding":false},{"id":401945,"name":"Zhou Li","orcid":"0000-0002-9952-7296","position":2,"is_corresponding":false},{"id":401946,"name":"Yuan Meng","orcid":"0000-0001-9603-9636","position":3,"is_corresponding":false},{"id":403310,"name":"Jiang Cheng","orcid":null,"position":4,"is_corresponding":false},{"id":401947,"name":"Lu Li","orcid":"0000-0002-2025-9074","position":5,"is_corresponding":false},{"id":401948,"name":"Qibing Pei","orcid":"0000-0003-1669-1734","position":6,"is_corresponding":false},{"id":401943,"name":"Yu Xie","orcid":"0000-0002-0088-6767","position":0,"is_corresponding":true}],"reference_count":45,"raw_metadata":null,"created_at":"2026-07-18T21:48:50.085103Z","pmid":"32691931","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
