In this paper, the influence of ester and alkyl groups on the molecular structure and wettability of the polymers were studied through varying # in the alkyl side groups. PHEMA#Cs with relatively longer alkyl side groups (#≥15) show bilayer lamellar structures with well aligned side chains giving rise to the very low surface energies, calculated from advancing contact angles, in the range of 22.7-22.8 mN/m. In contrast, PHEMA#Cs with shorter alkyl side groups with #≤13 have disordered structures on the polymer surfaces and stick-slip behavior was observed when water was used as the test liquid for the advancing contact angle measurements. Furthermore, the alignment behavior of nematic liquid crystal, 5CB on the PHEMA#C films could be correlated with the molecular structure and wettability of the polymers.","is_dataset_classified":null,"base_score":2.772588722239781,"endowment":2.772588722239781,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21612785","pmcid":null,"openalex_id":"https://openalex.org/W2054603712","authors":[],"funders":[],"total_grants":0,"fwci":0.4789,"citation_percentile":0.6286776,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":1},{"year":2014,"count":2},{"year":2015,"count":2},{"year":2016,"count":2},{"year":2019,"count":1},{"year":2021,"count":1},{"year":2023,"count":2},{"year":2024,"count":1},{"year":2025,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0021979711005066?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0021979711005066?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jcis.2011.04.070","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/21612785","host_type":"repository"}],"fields_of_study":["Liquid Crystal Research Advancements","Adhesion, Friction, and Surface Interactions","Surface Modification and Superhydrophobicity","Algorithms","Esters","Liquid Crystals","Molecular Structure","Particle Size","Polyhydroxyethyl Methacrylate","Surface Properties"],"mesh_terms":["Algorithms","Esters","Particle Size","Polyhydroxyethyl Methacrylate","Surface Properties","Molecular Structure","Liquid Crystals"],"keywords":["Alkyl","Side chain","Methacrylate","Lamellar structure","Polymer","Contact angle","Liquid crystal","Bilayer","Wetting","Materials science","Polymer chemistry","Pendant group","Amphiphile","Chemistry","Crystallography","Organic chemistry","Composite material","Copolymer","Membrane"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-12T17:12:17.807958Z","pmid":null,"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":[]}
