標準解讀

GB/T 44210-2024是一項針對納米技術(shù)領(lǐng)域中納米銀線透明導(dǎo)電薄膜的老化測試標準。該標準詳細規(guī)定了利用氙燈加速老化的試驗方法,旨在評估這類薄膜材料在模擬極端光照條件下的穩(wěn)定性和耐用性。以下是標準內(nèi)容的概述:

標準適用范圍

本標準適用于含有納米銀線的透明導(dǎo)電薄膜材料,這些材料廣泛應(yīng)用于觸控屏、柔性顯示器、太陽能電池及智能窗等領(lǐng)域。通過規(guī)定的氙燈加速老化試驗方法,可以快速預(yù)測和評估這些薄膜材料在長期使用或暴露于高強度光環(huán)境下的性能變化。

試驗原理與設(shè)備

  • 氙燈加速老化試驗:利用氙弧燈模擬自然太陽光譜,通過控制光強度、溫度、濕度等條件,加速材料老化過程,短時間內(nèi)獲得長期使用效果的數(shù)據(jù)。
  • 試驗設(shè)備:標準要求使用能提供連續(xù)光譜、光強可調(diào)的氙燈老化箱,同時需配備溫濕度控制系統(tǒng)以維持試驗所需的環(huán)境條件。

試驗條件與程序

  1. 樣品制備:規(guī)定了樣品的尺寸、數(shù)量及處理方式,確保所有測試樣本具有一致性。
  2. 環(huán)境參數(shù):詳細說明了試驗過程中所需的溫度、濕度、光照強度及照射周期的具體數(shù)值,以模擬特定的加速老化環(huán)境。
  3. 試驗周期:根據(jù)材料特性及預(yù)期應(yīng)用場景設(shè)定合適的曝光時間,通常遠短于實際應(yīng)用中的老化時間,以達到快速評估的目的。
  4. 性能評估:老化試驗前后,對樣品的光學(xué)性能(如透光率、霧度)、電學(xué)性能(電阻值、導(dǎo)電性)及結(jié)構(gòu)特性進行檢測,以評估老化影響。

結(jié)果分析與報告

標準指導(dǎo)如何根據(jù)測試數(shù)據(jù)評價納米銀線透明導(dǎo)電薄膜的老化程度,包括但不限于性能衰減率、穩(wěn)定性指標等。要求試驗報告應(yīng)包含詳細的試驗條件、測試結(jié)果及分析結(jié)論,以便于不同實驗室間的結(jié)果比對和驗證。

標準的實施與意義

該標準為納米銀線透明導(dǎo)電薄膜的生產(chǎn)商、研究機構(gòu)及質(zhì)量檢測部門提供了統(tǒng)一的測試方法,有助于提高產(chǎn)品性能評估的一致性和可靠性,加速新材料的研發(fā)與應(yīng)用進程,同時保障終端產(chǎn)品的質(zhì)量和使用壽命。

引言

隨著電容式觸控顯示屏的應(yīng)用越來越廣泛,從智慧教育、智慧會議,到智慧出行、智慧醫(yī)療和政務(wù)

等領(lǐng)域,電容式觸控屏的應(yīng)用需求日益增加。納米銀線透明導(dǎo)電薄膜具有透光率高、方阻低、柔性好的

特性,在柔性觸控屏以及剛性觸控屏感應(yīng)層的應(yīng)用中,有著獨特的優(yōu)點。

由于納米銀線透明導(dǎo)電薄膜材料在使用時經(jīng)常暴露在太陽輻射或玻璃后太陽輻射下,因此測定太陽

輻射、溫度、濕度及其他氣候因素對材料性能的影響非常重要。在實驗室設(shè)備中的暴露比在自然環(huán)境中

有更多的可控條件,為更加快速地測定太陽輻射、溫度、濕度對材料性能的影響,常采用將納米銀線透

明導(dǎo)電薄膜暴露于氙燈(模擬透過窗玻璃的日光光譜的人造光源)下的試驗方法,評價材料的耐光性

能,指導(dǎo)新材料的評估、篩選與研發(fā)改進。
