Issue 4 Pages 245-252,\u00a0<a href=\"https:\/\/doi.org\/10.11203\/jar.40.245\">https:\/\/doi.org\/10.11203\/jar.40.245<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why Is This Study Important?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Particle deposition on transparent surfaces is a common problem in glove boxes, industrial observation windows, transportation systems, and protective equipment. Accumulated particles reduce visibility, safety, and operational efficiency. This study investigated a simple nanoparticle-coating strategy to reduce particle adhesion while maintaining transparency. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Research Highlights<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The authors applied silica nanoparticle coatings onto acrylic substrates and polycarbonate substrates, after surface modification using polyethyleneimine. Unlike conventional approaches, the method uses water-based dispersions and avoids organic solvents, making it suitable for sensitive polymer materials. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Key Findings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The best performance was achieved using a silica concentration of 0.1 mass%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Particle adhesion forces decreased from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>39.0 nN to 5.4 nN for acrylic<\/li>\n\n\n\n<li>38.4 nN to 3.7 nN for polycarbonate<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">corresponding to reductions to approximately:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>13.8% of the original value (acrylic)<\/li>\n\n\n\n<li>9.6% of the original value (polycarbonate) <\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why Does It Work?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The nanoparticle coating creates microscopic surface roughness. This roughness reduces the actual contact area between particles and the substrate, thereby lowering adhesion forces. The concept is simple: <strong>less contact area means lower particle adhesion.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Significance for Aerosol Science<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The study demonstrates a practical application of nanoparticle engineering to control particle deposition. Potential applications include: glove boxes, radioactive-material handling systems, optical inspection windows, transparent protective covers, industrial process equipment, where visibility and contamination control are both critical. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"327\" height=\"311\" src=\"https:\/\/jaast.jp\/wp-content\/uploads\/2026\/09\/image-4.png\" alt=\"\" class=\"wp-image-1458\" srcset=\"https:\/\/jaast.jp\/wp-content\/uploads\/2026\/09\/image-4.png 327w, https:\/\/jaast.jp\/wp-content\/uploads\/2026\/09\/image-4-300x285.png 300w\" sizes=\"auto, (max-width: 327px) 100vw, 327px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\u672c\u8a18\u4e8b\u306f\u300e\u30a8\u30a2\u30ed\u30be\u30eb\u7814\u7a76\u300f\u63b2\u8f09\u8ad6\u6587\u3092\u5e83\u304f\u7d39\u4ecb\u3059\u308b\u305f\u3081\u3001\u65e5\u672c\u30a8\u30a2\u30ed\u30be\u30eb\u5b66\u4f1a\uff08JAAST\uff09\u304c\u4f5c\u6210\u3057\u305f\u89e3\u8aac\u8a18\u4e8b\u3067\u3059\u3002\u751f\u6210AI\u3092\u7de8\u96c6\u88dc\u52a9\u30c4\u30fc\u30eb\u3068\u3057\u3066\u6d3b\u7528\u3057\u3066\u3044\u307e\u3059\u304c\u3001\u5185\u5bb9\u306f\u539f\u8457\u8ad6\u6587\u306b\u57fa\u3065\u304d\u3001\u5b66\u4f1a\u62c5\u5f53\u8005\u304c\u78ba\u8a8d\u30fb\u7de8\u96c6\u3057\u3066\u3044\u307e\u3059\u3002\u7814\u7a76\u5185\u5bb9\u306e\u8a73\u7d30\u306b\u3064\u3044\u3066\u306f\u539f\u8457\u8ad6\u6587\u3092\u3054\u53c2\u7167\u304f\u3060\u3055\u3044\u3002<em>This article was prepared by the Japan Association of Aerosol Science and Technology (JAAST) to introduce research published in<\/em> Earozoru Kenkyu. <em>Generative AI was used as an editorial support tool.
