Abstract
本發明提出一種封裝膜、包括彼之有機電子裝置、及製造該有機電子裝置之方法。因此,本發明提出封裝膜,其可形成能夠有效地阻斷濕氣或水自外部進入有機電子裝置的結構,並在面板製程中具有極佳的加工性及在高溫度和高濕度條件下具有極佳的熱保留性。
Description
此申請案主張2015年2月4日向韓國智慧財產辦公室提出申請之韓國專利申請案第2015-0017620號之權利,茲將該案全文以引用方式納入本文中。
本申請案係關於封裝膜、包括彼之有機電子裝置(OED),及使用彼製造OED之方法。
OED係包括使用電洞和電子產生電荷交換之有機材料層的裝置,且OED可為,例如,光伏打裝置、整流器、發射器、或有機發光二極體(OLED)。
OED中,OLED具有較低的能量消耗和較高的回應速率,且比傳統光源更有利於較薄的顯示裝置或照明。此OLED亦具有極佳的空間施用性,且被預期施用於各種領域,包括所有種類的可攜式裝置、螢幕、筆記型電腦、和TV。
用於OLED的商品化和擴展用途,最關鍵的問題是耐久性。OLED中所含的有機材料和金屬電極極易被外在因素(如濕氣)所氧化。因此,包括OLED的產品對於環境因素非常敏感。因此,提出防止氧或濕氣自外部環境滲入OED(如OLED)的各種方法。
專利文件1中,揭示黏著性封裝組成物膜和有機電發光元件,且該組成物是以聚異丁烯(PIB)為基礎的壓感性黏著劑,但其在高溫度和高濕度條件下的加工性低和可靠性低。此外,在大尺寸平板面板的積層程序中,氣泡包封於面板之間,並因此而無法得到一致的積層性質。
因此,對於開發使得OED得以確保所須壽命,有效地防止濕氣滲入OED,維持在高溫度和高濕度條件下的可靠性,並具有極佳的積層性質(其為面板製程期間內要求的特性之一)之封裝劑有需求存在。
(專利文件1)韓國註冊專利申請案第2008-0088606號
本發明提出一種封裝膜,其可形成能夠有效地阻斷濕氣或水自外部進入OED的結構,並在面板製程中具有極佳的加工性及在高溫度和高濕度條件下具有極佳
的熱保留性。
下文中,參照附圖,將更詳細地描述本申請案的例示具體實施例。此外,為解釋本申請案,將省略已知通用功用或構造的詳細描述。此外,附圖係有助於瞭解本申請案之圖示。為更清楚地解釋本申請案,將省略與解說無關的零件,厚度經放大以清楚地展示數層和區域。本申請案之範圍不受限於圖中所示的厚度、尺寸和比。
本申請案係關於封裝膜。該封裝膜可用於封裝或包封OED,如OLED。
文中所謂“有機電子裝置(OED)”是具有包括在一對彼此面對的電極之間使用電洞和電子交換電荷的有機材料層之結構的產品或裝置,且OED的例子可包括,但本申請案不限於,光伏打裝置、整流器、發射器、和OLED。本申請案的例示具體實施例中,OED可為OLED。
本申請案之封裝膜可密封OED的有機電子元件的全表面,以保護元件使其不受到濕氣或氧的影響。此封裝膜可包括自丁烯衍生的聚合物和符合通式1的壓感性黏著層。
例示封裝膜的壓感性黏著層符合通式1。
通式1中,d是當藉由在金屬底板的一面上形成具有50μm厚度的壓感性黏著層而製得樣品以
1cm×1cm的黏著區域內接合至玻璃時,且500g的重量於85℃於重力方向載於金屬底板上1小時之時,蠕變的壓感性黏著層的蠕變距離。此處,金屬底板可由銅、鋁、鎳、鐵鎳合金或不銹鋼(SUS)所形成。詳細言之,包括壓感性黏著層和金屬底板之積層樣品的壓感性黏著層表面以1cm×1cm的黏著區域內接合至玻璃,並如前述地將重量載於金屬底板。可以在金屬底板移動距離中測得壓感性黏著層的蠕變距離。該通式中,d可為1mm或更小,例如,990μm或更小,950μm或更小,800μm或更小,700μm或更小,600μm或更小,或400μm或更小。

芳基。n是0至10的數字,當n是0時,U可直接鏈接至-O-Q。由於本申請案之壓感性黏著劑組成物包括疏水性聚合物和特定的式1的化合物,所以當施用於封裝有機電子元件時,該組成物在面板的製程期間內展現極佳的加工性且在高溫度和高濕度條件下展現極佳的熱保留性。
例示具體實施例中,該組成物包括60至95重量份之自丁烯衍生的聚合物和5至40重量份之符合式1的化合物。例示具體實施例中,該組成物包括60至90重量份之自丁烯衍生的聚合物和10至40重量份之符合式1的化合物,或65至90重量份之自丁烯衍生的聚合物和10至35重量份之符合式1的化合物。本申請案中,隨著組份含量調整於上述範圍內,可實現極佳的濕氣阻斷性和在高溫度和高濕度條件下的熱保留性。式1的化合物可包括,但未特別限於,丙烯酸正辛酯、丙烯酸異辛酯、丙烯酸異壬酯、丙烯酸月桂酯、丙烯酸硬脂酯、丙烯酸異硬脂酯、丙烯酸異癸酯、丙烯酸2-(2-乙氧基乙氧基)乙酯、丙烯酸甲氧基三乙二醇酯、或丙烯酸甲氧基聚乙二醇酯。

狀。此烯基亦可任意地經至少一個取代基取代。
除非特別界定,否則文中所謂“伸烷基”或“亞烷基”可為具2至30,2至25,2至20,2至16,2至12,2至10,或2至8個碳原子的伸烷基或亞烷基。此伸烷基或亞烷基可為直鏈、支鏈或環狀。此伸烷基或亞烷基亦可任意地經至少一個取代基取代。
除非特別界定,否則文中所謂“芳基”可為自包括苯的結構、或二或更多個苯稠合或偶合之化合物或其衍生物衍生的單價殘基。此芳基可具有6至22,較佳地6至16,且更佳地6至13個碳原子,且可為,例如,苯基、苯乙基、苯丙基、苄基、甲苯基、二甲苯基或萘基。
“自丁烯衍生的聚合物”是指聚合物的一或多個聚合單元衍生自丁烯。由於自丁烯衍生的聚合物的極性極低,所以作為封裝劑或包封劑時,其透明且幾乎沒有腐蝕的影響,該聚合物展現極佳的濕氣阻斷性和極佳的耐久性和可靠性。
本申請案中,自丁烯衍生的聚合物亦可為丁烯單體的均聚物;丁烯單體與不同的可聚合單體共聚而形成的共聚物;使用丁烯單體的反應性低聚物,或彼等之混合物。本申請案中衍生的聚合物是指聚合單體單元形成的聚合物。該丁烯單體可包括,例如,1-丁烯、2-丁烯或異丁烯。
丁烯單體或能夠與衍生物聚合之不同的單體可包括,例如,異戊二烯、苯乙烯或丁二烯。使用共聚物
時,可維持物理性質(如加工性和交聯度),並因此,當施用於OED時,可確保壓感性黏著劑本身的耐熱性。
使用丁烯單體的反應性低聚物亦可包括具有反應性官能基的丁烯聚合物。該低聚物可具有500至5000的重量平均分子量。該丁烯聚合物亦可鏈接至具有反應性官能基之不同的聚合物。該不同的聚合物可為(甲基)丙烯酸烷酯,但本申請案不限於此。該反應性官能基可為羥基、羧基、異氰酸酯基或含氮的基團。該反應性低聚物和不同的聚合物亦可藉多官能性交聯劑(其可為選自由異氰酸酯交聯劑、環氧基交聯劑、氮沅交聯劑和金屬鉗合交聯劑所組成之群組中之一或多者)交聯。
例示具體實施例中,本申請案之自丁烯衍生的聚合物可為二烯和包括一個碳-碳雙鍵之以烯烴為基礎的化合物之共聚物。此處,以烯烴為基礎的化合物可包括丁烯,二烯可為能夠與以烯烴為基礎的化合物聚合的單體,例如,異戊二烯或丁二烯。例如,包括碳-碳雙鍵之以烯烴為基礎的化合物和二烯之共聚物可為丁基橡膠。
本申請案中,該聚合物可具有某些重量平均分子量(MW),使得壓感性黏著劑組成物可模製成膜形狀。例如,該聚合物可具有約10,000至2,000,000,10,000至1,000,000,10,000至500,000或10,000至300,000的重量平均分子量。本申請案中,“重量平均分子量”是藉凝膠穿透層析法(GPC)測得之相關於聚苯乙烯標準品的值。但是,上述重量平均分子量不須具有樹脂組
份。例如,當樹脂組份的分子量不足以形成膜時,個別的黏合劑樹脂可摻合於壓感性黏著劑組成物中。“聚合物”和“樹脂組份”彼此可具有相同的意義。
本申請案之例示具體實施例中,該壓感性黏著層可以另包括多官能性活性能量射線可聚合的化合物,其可藉由以活性能量射線照射而聚合。該活性能量射線可聚合的化合物可符合式2。

符合式2之活性能量射線可聚合的化合物特別地具有與本申請案之聚合物之極佳的相容性,並因此可符合在高溫度和高濕度條件下的可靠性。例如,活性能量射線可聚合的化合物與上述自丁烯衍生的聚合物可使得壓感性黏著劑組成物具有極佳的濕氣阻斷性和在高溫度和高濕度條件下之極佳的可靠性。
該活性能量射線可聚合的化合物是指包括二或更多個能夠藉由以活性能量射線照射而參與聚合反應的官能基之化合物,例如,官能基包括似伸乙基的不飽和雙

相對於100重量份該活性能量射線可聚合的化合物,該自由基引發劑的含量為0.2至20重量份,0.5至18重量份,1至15重量份,或2至13重量份。因此,有效地誘發活性能量射線可聚合的化合物之反應,且可防止壓感性黏著組成物的物理性質因為固化之後殘留的組份而退化。

更多者作為濕氣清除劑時,可使用經煅燒的白雲石。
該濕氣清除劑可根據其用途而控制於適當尺寸。一個例示具體實施例中,濕氣清除劑的平均粒子尺寸可控制於約10至15000nm。具有以上範圍的尺寸之濕氣清除劑由於濕氣清除劑與濕氣的反應速率不會過高而易儲存,且可以有效地移除濕氣且不會損及待封裝的元件。
考慮所欲的阻斷性,可以無特別限制地適當地選擇濕氣清除劑的含量。

通式2中,σ1是在該壓感性黏著劑層製成600μm厚時,在先進的流變膨脹系統(ARES)的應力鬆弛試驗模式中,使用直徑為8mm的平面模具,藉由於85℃施用約200gf的正向力,當30%應變用於膜時,測得的最大應力值,而σ2是施用至該膜的該應變維持180秒之後測得的應力值。特定言之,該壓感性黏著劑層先製成600μm厚度,使用先進的流變膨脹系統(ARES)的應力鬆弛試驗模式。此處,使用具有8mm直徑的平面模具於85℃施用約200gf的正向力。σ1是30%應變施用於該膜時測得的最大應力值,而σ2是施用至該膜的該應變維持180秒之後測得的值。
如前述者,該封裝膜可用以封裝或包封OED,如OLED。展現該值(Ep)範圍的該封裝膜所形成的封裝或包封結構具有極佳的耐久性,當用於封裝或包封程序,在高溫耐久性試驗條件下,不會產生氣泡。例示具體實施例中,如之後描述者,該封裝膜可用以形成覆蓋OED元件的頂和側面之封裝或包封結構。
“先進的流變膨脹系統(ARES)”是流變計,其用以評估材料的黏彈性,如黏度、切變模數、耗損因子和儲存模數。此儀器係機械測定裝置,其可以使得樣品處於動力狀態和正常狀態並測定樣品承受所施用的前述應力
之轉矩(transfer torque)。
例示具體實施例中,本申請案之封裝膜可直接接合至該壓感性黏著層的該第一層上的金屬層。文中所謂“直接接合”是指沒有層介於兩層之間。該第二層可接合至有元件形成於其上的基板以完全封住該元件。即,該第二層可以直接接合至該基板。
例示具體實施例中,例示封裝膜的該第一層藉上述通式2計算的Ep值可為30至80%,30至75%或30至70%。該第二層藉上述通式2計算的Ep值亦可為8至40%,10至40%或20至40%。本申請案中,考慮該第一層直接接合至該金屬層,藉由將Ep值控制於以上範圍內,可以極佳地維持該第一層的黏著耐久性和可靠性。本申請案中,藉由將Ep值控制於以上範圍內,亦可達到介於基板和第二層的封裝膜之間的積層品質。根據本申請案的第一層的彈性部分的值可以與第二層的彈性部分的值相同或高於後者,但本申請案不限於此。
本申請案之例示具體實施例中,該第一層具有在50至500gf範圍內之根據ASTM D2979測得的探頭黏力,且特定言之,該第一層具有60至450gf或70至400gf的探頭黏力。該第二層亦具有在3至100gf範圍內之根據ASTM D2979測得的探頭黏力,且特定言之,該第二層具有3至90gf的探頭黏力。
製成100μm厚度時,根據本申請案之封裝膜的壓感性黏著層亦具有50、40、30、20或10g/m2.天或
更低的水蒸氣穿透率(WVTR),此係於100℉和100%的相對濕度在膜的厚度方向測得。壓感性黏著劑之組成或交聯條件經調整以具有此WVTR時,當壓感性黏著劑施用於電子裝置的封裝或包封結構時,該封裝或包封結構有效地阻斷濕氣或氧自外部滲透並因此而安定地保護該元件。WVTR越低,展現的濕氣阻斷性越佳,並因此,下限可為,但未特別限於,例如,0g/m2.天。
本申請案之例示具體實施例中,該封裝膜可以另包括金屬層。根據本申請案之例示具體實施例中之金屬層可為透明或不透明。該金屬層可藉由使金屬澱積於薄金屬箔或聚合物底膜上而形成。具有導熱性和濕氣阻斷性的任何材料可以無限制地用於該金屬層。該金屬層包括金屬、金屬氧化物、金屬氮化物、金屬碳化物、金屬氧氮化物、金屬氧硼化物、和其摻合物中之任一者。例如,該金屬層可包括二或更多種金屬的合金,例如,鐵-鎳合金。例示具體實施例中,該金屬層亦可包括金屬氧化物,如氧化矽、氧化鋁、氧化鈦、氧化銦、氧化錫、氧化錫銦、氧化鉭、氧化鋯、氧化鈮或其摻合物。該金屬層可以使用用於電解、滾軋、熱蒸發、電子束蒸發、濺鍍、反應性濺鍍、化學蒸鍍、電漿化學蒸鍍或電子迴旋加速器共振電漿源化學蒸鍍的設備澱積。本申請案的一個例示具體實施例中,該金屬層可藉反應性濺鍍澱積。
較佳地,該金屬層具有50W/mK或更高,60W/mK或更高,70W/mK或更高,80W/mK或更高,90
W/mK或更高,100W/mK或更高,110W/mK或更高,120W/mK或更高,130W/mK或更高,140W/mK或更高,150W/mK或更高,200W/mK或更高,或250W/mK或更高的導熱性。由於高導熱性,所以在使金屬層積層的程序中,於積層界面處產生的熱會迅速消散。因為高導熱性,所以在OED的操作中累積的熱也會迅速消散至外部,並因此而使得OED本身的溫度維持於較低溫度,且可減少破裂和缺陷。
文中所用“導熱性”可為藉傳導而能夠轉移熱的程度,其單位是W/mK。此單位是材料於相同溫度和距離的熱傳導程度,且是指相關於距離的單位(m)和溫度的單位(K)之熱的單位(watt)。
例如,本申請案之封裝膜的壓感性黏著層具有5000至107Pa.s的Mooney黏度(η*),此使用具有8mm直徑的平面模具以5%應變、1Hz頻率和在30至150℃範圍內的任一溫度之切應力測得。Mooney黏度可藉已知方法,例如,ARES(TA)測得。黏度範圍可為,例如,5,000至107Pa.s,5,000至106Pa.s或5,000至5×105Pa.s。金屬層可以另含括於符合該黏度範圍的壓感性黏著層的一面上。符合該黏度範圍的壓感性黏著層可包括上述式1的化合物或活性能量射線可聚合的化合物。
該封裝膜可以另包括底膜或脫模膜(下文中,可能稱為“第一膜”),並具有壓感性黏著劑形成於底膜或脫模膜上的結構。該結構可以另包括形成於壓感性黏
著劑上的底膜或脫模膜(下文中,亦稱為“第二膜”)。
圖1和2是根據本申請案之例示具體實施例中之封裝膜的截面圖。
如圖1所示者,本申請案之封裝膜包括壓感性黏著層12和金屬層13,彼等形成於底膜或脫模膜11上。圖2亦出示壓感性黏著層12,其包括第一層12a和第二層12b。
未特別限制可用於本申請案中之第一膜的特定類型。本申請案中,可以使用,例如,此技術中使用的通用聚合物膜作為第一膜。本申請案中,例如,底膜或脫模膜可為聚對酞酸乙二酯膜、聚四氟乙烯膜、聚乙烯膜、聚丙烯膜、聚丁烯膜、聚丁二烯膜、氯乙烯共聚物膜、聚胺甲酸乙酯膜、乙烯-乙酸乙烯酯膜、乙烯-丙烯共聚物膜、乙烯-丙烯酸乙酯共聚物膜、乙烯-丙烯酸甲酯共聚物膜或聚醯亞胺膜。底膜或脫模膜的一或兩面亦可經適當脫模處理。用於底膜之脫模處理的脫模劑的例子可為以醇酸、聚矽氧、氟、不飽和酯、聚烯烴或蠟為基礎的脫模劑,且用於耐熱性,可使用以醇酸、聚矽氧或氟為基礎的脫模劑,但本申請案不限於此。
本申請案中,未特別限制底膜或脫模膜(第一膜)的厚度,且可根據用途經適當選擇。例如,本申請案中,第一膜的厚度可為約10至500μm,且較佳地為約20至200μm。當厚度低於10μm,底膜容易在製程中變形,而當厚度超過500μm時,經濟效益降低。
未特別限制本申請案的封裝膜中所含括之壓感性黏著層的厚度,且可根據以下條件,考慮膜的用途作適當選擇。該壓感性黏著層的厚度可為5至200μm,且較佳地為5至100μm。該壓感性黏著層的厚度低於5μm時,無法確保足夠的黏著性,且在程序期間內的濕氣阻斷能力耗損會提高。厚度超過200μm時,難確保加工性,暴於側面的空間會膨脹,使得濕氣阻斷性退化,耐熱性退化,且經濟效益降低。
本申請案亦係關於封裝膜之製法。藉由將壓感性黏著層模製成膜或片狀,可製得例示封裝膜。
例示具體實施例中,該方法包括將包括構成上述壓感性黏著層之組份的塗覆液以膜或片狀施用於底膜或脫模膜,及乾燥所施用的塗覆液。
該塗覆液,例如,可藉由將上述各壓感性黏著層的組份溶解或分散於適當溶劑中而製得。例示具體實施例中,必要時,該壓感性黏著層可藉由將濕氣清除劑或填料溶解或分散於溶劑中,及使濕氣清除劑或填料在研磨之後與封裝樹脂混合而製得。
未特別限制製備塗覆液中所用溶劑類型。但是,溶劑的乾燥時間過長或須於高溫乾燥時,會發生與封裝膜的操作性或耐久性相關的問題,因此可使用揮發溫度為150℃或更低的溶劑。考慮膜的模製性,混合及使用少量具有以上範圍或更高之揮發溫度的溶劑。可以使用甲基乙基酮(MEK)、丙酮、甲苯、二甲基甲醯胺(DMF)、
甲基溶纖素(MCS)、四氫呋喃(THF)、二甲苯和N-甲基吡咯烷酮(NMP)中之一或二或更多者作為溶劑,但本申請案不限於此。
未特別限制將塗覆液施用至底膜或脫模膜的方法,且因此可為,例如,已知塗覆法,如刮刀塗佈、滾輪塗佈、噴霧塗佈、凹版塗佈、淋幕塗佈、刮刀式塗佈或澆斗嘴塗佈。
施用的塗覆液經乾燥,溶劑經揮發,藉此形成壓感性黏著層。乾燥可以,例如,於70至150℃進行1至10分鐘。可以考慮所用溶劑而改變乾燥條件。
未特別限制堆疊第一層和第二層之方法。例如,該第一層和該第二層,其形成於各自的脫模膜上,可經積層,藉此形成多層封裝膜,或該第二層可直接形成於該第一層上且反之亦然。
乾燥之後,金屬層可形成於該壓感性黏著層上。形成金屬層之方法可為此技術已知的技術。例如,金屬層可製成金屬箔片,或藉由將金屬澱積於聚合物基底上而形成。例如,可藉電解或滾軋形成金屬層。
本申請案亦係關於OED。該OED可包括基板;形成於該基板上的有機電子元件;和封裝有機電子元件的全表面(例如,所有的頂和側面)的封裝膜。該封裝膜可包括含有處於交聯狀態的壓感性黏著劑組成物之壓感性黏著層。該封裝膜可以另包括形成於壓感性黏著層上的金屬層。
此處,有機電子元件可為,例如,有機發光元件。
本申請案亦係關於製造OED之方法。該OED可以使用,例如,封裝膜,製得。
壓感性黏著層可製成在OED中展現極佳的濕氣阻斷性並有效地固定和支撐基板和金屬層的結構。
此外,無論OED的類型(例如,頂部發射或底部發射類型),該壓感性黏著層維持安定。
此處所謂“壓感性黏著層”是指覆蓋有機電子元件頂面和側面全數的壓感性黏著劑。
圖3是例示OED的圖示,其中有機電子元件是有機發光元件。
欲製造OED,例如,可以將上述封裝膜施用於有機電子元件已形成於其上的基板以覆蓋有機電子元件的全表面;及固化該封裝膜。
文中所謂“固化”是指經由加熱或UV照射而將本申請案的壓感性黏著劑組成物加以交聯,藉此製得壓感性黏著劑。
詳細言之,經由真空澱積或濺鍍,藉由在作為基板的玻璃或聚合膜上形成透明電極,在透明電極上形成發光有機材料層(例如,由電洞傳輸層、發射層和電子傳輸層所組成),及進一步在其上形成電極層,可形成有機電子元件。之後,配置封裝膜的壓感性黏著層以覆蓋已經經過上述程序之基板的有機電子元件的全表面。
例示具體實施例中,如圖3所示者,可配置用於封裝OED的產品,使得封裝膜的壓感性黏著層12之配置與OED22和基板21接觸。金屬層13亦配置於壓感性黏著層12上。
本申請案提出封裝膜,其可形成能夠有效地阻斷濕氣或氧自外部進入OED的結構,且及在高溫度和高濕度條件下具有極佳的熱保留性。
