Abstract
本揭露提供一種樹脂組合物,包括:第一彈性分子鏈段改質的環氧樹脂與環氧樹脂固化劑反應形成的一第一聚合物;以及第二彈性分子鏈段改質的丙烯酸酯聚合而成的一第二聚合物。
Description
本揭露關於樹脂,更特別關於樹脂組合物、封裝結構,以及樹脂組合物的形成方法。
透明顯示器及可摺式顯示器在不同場域之應用(如:智慧育樂、零售等開放式空間或個人使用之可撓式手機、平板及筆電等)常面臨民眾手指觸碰或撞擊之情境。因此,顯示面板除了需具備防刮、耐磨外,還需一定程度之耐衝擊特性。有鑑於此,增加顯示器之耐衝擊特性勢在必行。
目前由國際知名膠材企業研發之高阻尼感壓膠材商品,可表現出低溫性能和粘附性,並可用於製造減振複合材料,但並非透明顯示器領域應用所需之撞擊吸能材料。而目前國際上多以壓克力(如:3M公司)或矽膠(如:General Silicone、Shin-Etsu Chemical、Dow Corning等公司)之高分子為主。
綜上所述,目前亟需開發新的耐衝擊透明之材料。
本揭露一實施例提供之樹脂組合物,包括:第一彈性分子鏈段改質的環氧樹脂與環氧樹脂固化劑反應形成的第一聚合物,以及第二彈性分子鏈段改質的丙烯酸酯聚合而成的第二聚合物。
本揭露一實施例提供之封裝結構,包括:光電元件,以及封裝膜以封裝光電元件。封裝膜包括:第一彈性分子鏈段改質的環氧樹脂與環氧樹脂固化劑反應形成的第一聚合物,以及第二彈性分子鏈段改質的丙烯酸酯聚合而成的第二聚合物。
本揭露一實施例提供之樹脂組合物的形成方法,包括:混合第一彈性分子鏈段改質的環氧樹脂、環氧樹脂固化劑、第二彈性分子鏈段改質的丙烯酸酯、與起始劑,以環氧樹脂固化劑固化第一彈性分子鏈段改質的環氧樹脂,形成第一聚合物,以及以起始劑聚合第二彈性分子鏈段改質的丙烯酸酯,形成第二聚合物。
本揭露一實施例提供之樹脂組合物,可包括,但不限於,第一彈性分子鏈段改質的環氧樹脂與環氧樹脂固化劑反應形成的第一聚合物,以及第二彈性分子鏈段改質的丙烯酸酯聚合而成的第二聚合物。上述的彈性分子可為具有彈性的物質,受應力容易延伸,而應力消失後,會回復原狀。
在一些實施例中,上述的第一聚合物與第二聚合物互穿,例如可形成互穿網狀聚合物(Interpenetrating Polymer Network,IPN),但不限於此。若第一聚合物與第二聚合物非互穿,則材料使用之溫域範圍變狹窄。舉例來說,環氧樹脂僅帶有獨立反應之環氧基,而丙烯酸酯僅帶有雙鍵,故環氧基和雙鍵結構彼此不發生交聯反應,如此一來,才有機會形成互穿網狀結構。
在一些實施例中,上述的第一彈性分子鏈段與該第二彈性分子鏈段相同,若上述的分子鏈段不同,則增加材料霧度而影響光學特性。一般而言,上述的分子鏈段包括聚氨酯(polyurethane)、橡膠(rubber)、二聚體酸(dimer acid)、聚醚(polyether)、聚酯(polyester)或上述之組合,但不限於此。
在一些實施例中,上述的第一彈性分子鏈段與該第二彈性分子鏈段均為脂肪族(aliphatic),例如可為聚醚類脂肪族、聚酯類脂肪族,或上述之組合,但不限於此。
在一些實施例中,上述的第一彈性分子鏈段與該第二彈性分子鏈段均為芳香族(aromatic),例如可為苯環類芳香族、萘環類芳香族、蒽環類同分異構物,或上述之組合,但不限於此。
在一些實施例中,上述的第一彈性分子鏈段改質的環氧樹脂與第二彈性分子鏈段改質的丙烯酸酯的重量比為約1:0.45至1:10。例如約1:0.5至1:8、約1:0.5至1:6、約1:0.5至1:4、約1:0.5至1:2、約1:1至1:8、約1:1至1:6、約1:1至1:4、約1:1至1:2等,但不限於此。若第二彈性分子鏈段改質的丙烯酸酯之比例過低,則材料使用之溫域範圍狹窄;若第二彈性分子鏈段改質的丙烯酸酯之比例過高,則材料阻尼峰值下降。
在一些實施例中,上述的第一彈性分子鏈段改質的環氧樹脂與該環氧樹脂固化劑的重量比為約1:0.2至1:0.8之間,但不限於此。若環氧樹脂固化劑之比例過低,則硬化不完全。上述的環氧樹脂固化劑種類可包含胺類或酸酐類,但不限於此;環氧樹脂固化劑分子量約230至5000,但不限於此。
在一些實施例中,樹脂組合物之霧度≤0.5%。若霧度大於0.5%,則不適合使用於強調透明性之機構。
在一些實施例中,樹脂組合物之穿透度≥90%。若穿透度小於90%,則不適合使用於強調透明性之機構。
在一些實施例中,樹脂組合物在-20℃至50℃的Tan δ峰值為0.7至1.2。此外,樹脂組合物的Tan δ峰值≥0.7的溫度上限與溫度下限之間的差異可為10℃至30℃。Tan δ值的定義為E"/E',表示通過材料分子內部運動所耗散的能量。
本揭露一實施例提供之一種封裝結構,可包括,但不限於,光電元件,以及封裝膜以封裝光電元件。上述的光電元件可包括LCD、OLED、Micro LED等,但不限於此。上述的封裝膜,舉例來說,可包括第一彈性分子鏈段改質的環氧樹脂與環氧樹脂固化劑反應形成的第一聚合物,以及第二彈性分子鏈段改質的丙烯酸酯聚合而成的第二聚合物,但不限於此。
本揭露另一實施例提供之一種樹脂組合物的形成方法,可包括:混合第一彈性分子鏈段改質的環氧樹脂、環氧樹脂固化劑、第二彈性分子鏈段改質的丙烯酸酯、與起始劑,以環氧樹脂固化劑固化第一彈性分子鏈段改質的環氧樹脂,形成第一聚合物;以及以起始劑聚合第二彈性分子鏈段改質的丙烯酸酯,形成第二聚合物,但不限於此。舉例來說,起始劑(initiator)可為光起始劑(例如UV光起始劑)、熱起始劑等,或上述之組合,但不限於此。上述的光起始劑種類可為自由基反應型、陽離子反應型及陰離子反應型。上述的樹脂組合物與前述類似,在此不重述。
在一些實施例中,樹脂組合物的形成方法可為同時固化第一彈性分子鏈段改質的環氧樹脂與聚合第二彈性分子鏈段改質的丙烯酸酯。舉例來說,可同時以UV光照射及加熱的方式聚合而成。
在一些實施例中,樹脂組合物的形成方法可為分開固化第一彈性分子鏈段改質的環氧樹脂與聚合第二彈性分子鏈段改質的丙烯酸酯。舉例來說,可先以UV光照再加熱的方式聚合而成。使用上述兩階段分開固化與聚合,可填補凹凸或平坦結構的顯示器面板,滿足封裝製程需求。
以突破效益來說,本揭露之彈性/軟性耐高溫透明膜層材料在廣溫性、耐衝擊性及光學特性等技術皆較為領先,其將可整合至透明顯示器、一般顯示器、可撓式顯示器等產品上,且可滿足高效能LTPS TFT製程需求。

實施例6
接下來對實施例1~5以及比較例1~10之材料做霧度(Haze)、光穿透度(Total transmittance, T.T.)及Tan δ 峰值測試。參考ASTM D1003規範量測材料光學特性及IPC-TM-650規範做動態機械分析(Dynamic mechanism analysis, DMA)之Tan δ峰值量測,並於-50 ℃~50 ℃溫度掃描,找出Tan δ峰值及Tan δ峰值≧0.7之溫域範圍並計算差值,結果如表1所示。
表1
(N.A. = Not Applicable)
No. | 材料 (聚氨酯改質的環氧樹脂和聚氨酯改質的丙烯酸酯之重量比) | 霧度Haze (%) | 光穿透度T.T. (%) | Tan δ 峰值 | Tan δ峰值≧0.7之溫域範圍 (差值)(℃) |
實施例1 | 1:0.50 | 0.2 | 92.2 | 1.1 | 14~35 (21) |
實施例2 | 1:0.63 | 0.2 | 91.6 | 1.1 | 11~32 (21) |
實施例3 | 1:1.26 | 0.2 | 92.4 | 1.1 | 0~30 (30) |
實施例4 | 1:1.52 | 0.3 | 92.0 | 1.2 | -17~10 (27) |
實施例5 | 1:6.67 | 0.2 | 92.5 | 1.0 | 28~48 (20) |
比較例1 | 1:12.59 | 0.2 | 92.4 | 0.6 | N.A. (Tan δ峰值未≧0.7) |
比較例2 | 1:0.40 | 0.2 | 92.1 | 1.0 | 16~23 (7) |
由表1結果可知,實施例1~5霧度皆≤0.5 %、光穿透度皆≥90 %、Tan δ峰值皆≥0.7及Tan δ峰值≥0.7之溫域範圍(差值)皆≥20℃,甚至達到30℃的區間。在比較例1、2之Tan δ峰值測試結果發現,當聚氨酯改質的丙烯酸酯比例較高時,Tan δ峰值則<0.7;當聚氨酯改質的丙烯酸酯比例較低時,Tan δ峰值維持1.0且Tan δ峰值≥0.7的溫域範圍(差值)<20℃。
表2
(N.A. = Not Applicable;N.D. = Not Detected)
No. | 材料 | 霧度Haze (%) | 光穿透度T.T. (%) | Tan δ 峰值 | Tan δ峰值≧0.7之溫域範圍 (差值)(℃) |
比較例3 | 透明玻璃片 | 0.2 | 92.0 | N.A. | N.A. |
比較例4 | 透明矽膠片 | 15.5 | 91.6 | N.D. | N.D. |
比較例5 | 聚氨酯改質的環氧樹脂 | 0.2 | 92.0 | 1.1 | 21~29 (8) |
比較例6 | 聚氨酯改質的丙烯酸酯 | 0.2 | 92.4 | 0.6 | N.A. |
比較例7 | 不同種聚氨酯鏈段之聚氨酯改質的環氧樹脂和聚氨酯改質的丙烯酸酯 | 92.0 | 84.2 | 1.1 | 2~23 (21) |
比較例8 | 環氧樹脂和聚氨酯改質的丙烯酸酯 | 67.7 | 90.6 | 1.0 | 15~28 (13) |
比較例9 | 聚氨酯改質的環氧樹脂和丙烯酸酯 | 0.9 | 91.2 | 0.7 | 9~14 (5) |
比較例10 | 環氧樹脂和丙烯酸酯 | 0.4 | 92.1 | 0.5 | N.A. |
由上表可知,實施例1~5的霧度、光穿透度、Tan δ峰值及溫域範圍(差值)明顯優於傳統的透明玻璃片及透明矽膠片。
若單純使用聚氨酯改質的環氧樹脂(比較例5),則在Tan δ峰值≥0.7之溫域範圍(差值)小於10℃,若單純使用聚氨酯改質的丙烯酸酯(比較例6),則Tan δ峰值未達0.7。
若聚氨酯改質的環氧樹脂和聚氨酯改質的丙烯酸酯選用不同種類鏈段的聚氨酯,則會造成相容性變差,霧度大幅增加且穿透度降低。
若選用環氧樹脂(無聚氨酯改質) 和聚氨酯改質的丙烯酸酯,則亦會造成霧度大幅增加現象。若選用聚氨酯改直的環氧樹脂和丙烯酸酯(無聚氨酯改質),則Tan δ峰值≥0.7之溫域範圍(差值)為5℃。若環氧樹脂和丙烯酸酯兩者皆無聚氨酯改質,則霧度較差、Tan δ峰值未達0.7。
由上述可知,本揭露之彈性/軟性耐高溫透明膜層材料在廣溫性、耐衝擊性(高阻尼)及光學特性等技術皆較為領先,其將可整合至透明顯示器、一般顯示器、可撓式顯示器等產品上,且可滿足高效能LTPS TFT製程需求。
雖然本揭露已以數個較佳實施例揭露如上,然其並非用以限定本揭露,任何所屬技術領域中具有通常知識者,在不脫離本揭露之精神和範圍內,當可作任意之更動與潤飾,因此本揭露之保護範圍當視後附之申請專利範圍所界定者為準。
