The results show that the density of glass, glass transition temperature and thermal expansion coefficient increase with the increase of yttria content, and the chemical durability decreases with the increase of yttria content. The bend strength of glass increases from 53.52 MPa to 109.65 MPa when 1.80% Y2O3 is added into glass. However, with the content of yttria further increases to 6.84%, the bend strength is suspended about 110 MPa. Y2O3 acting as network modifies in the structure and makes the island-shape network unit repolymerization by the bonding of Ge-O-Y because of the decrease of non-bridge oxygens and strengthening of glass network structure.

Via XRD analysis, we found that the ZnO nanoparticles had been dissolved more severely as the portion of acrylic acid in the ABM copolymer raised. In DSC and DMA analysis, we found that ZnO nanoparticles and ABM copolymers had no apparent influence on the glass transition temperature and the mechanical strength of PMMA matrix. Data from TGA analysis indicate that ZnO nanoparticles evidently enhance the thermal stability of PMMA matrix. However, the addition of the easily decomposed ABM copolymers in PMMA reduces the thermal stability of PMMA matrix. Via UV-vis analysis, we observed that adding ZnO nanoparticles into PMMA matrix dramatically decreased the transparency of ZnO/PMMA nanocomposites films. Whereas adding ABM copolymers into ZnO/PMMA nanocomposites as the compatibilizers can increase the transparency of ZnO/PMMA nanocomposites films. Hence, it`s obvious that the ABM copolymers improved the dispersibility of ZnO nanoparticles in PMMA matrix. After inspected by SEM and TEM analysis, we found that if ZnO/PMMA nanocomposites containing ABM copolymers as compatibilizers, ZnO nanoparticles would loosely and widely disperse in PMMA matrix. In addition, the capability of ABM copolymer to improve the dispersibility of ZnO nanoparticles increases with the portion of acrylic acid in the ABM copolymer. Therefore, we suggest that the amount of carboxylic acid groups in ABM copolymer is one of the important factors to aid the dispersion of ZnO nanoparticles in PMMA matrix.
由XRD分析得知当复材中的ABM共聚物的AA比例越高时，其溶解ZnO粒子的现象就越严重；由DSC与DMA分析得知ZnO粒子与ABM共聚物并不会对PMMA高分子的玻璃转移温度与机械强度有显著的影响；由TGA分析得知ZnO粒子可有效地提升PMMA高分子的热稳定性，而复材中加入易热裂解的ABM共聚物却会降低PMMA高分子的热稳定性；由UV-vis分析得知当PMMA基材中加入ZnO粒子时会大幅降低可见光(550 nm)对ZnO/PMMA复材薄膜之透射度，而复材中加入ABM共聚物会则会提升ZnO/PMMA复材薄膜的可见光之透射度，显示ABM共聚物可改善ZnO粒子於PMMA基材中的分散性；而由SEM与TEM分析亦可以观察出当ZnO/PMMA复材中加入ABM共聚物时，其ZnO粒子的分散情形较松散且分散范围较广；另外，当ABM共聚物中AA的比例越高时，其帮助ZnO粒子分散的功能就越显著，由此可知ABM共聚物中的羧酸官能基是本研究中提升ZnO粒子分散性的一个主要因素。
