具体悬赏项目：

金发项目A1

碳纤维增强的PP热塑性复合材料的界面相容性以及适合PP树脂的碳纤维上浆剂开发. Interface compatibility of PP thermoplastic composites reinforced by carbon fiber, as well as carbon fiber sizing agent for PP resin development.

要求：通过对碳纤维上浆后，大幅提高PP碳纤维复合材料的力学性能,和加工性能. Through the carbon fiber sizing, a substantial increase in mechanical properties and machining performance of PP carbon fiber composite materials can be achieved.

金发项目A2

可微波加热的PP及PA树脂的微波吸收剂材料，同时具有较好的后端可加工性能，即兼顾加工粘度和材料各项力学性能 Microwave absorber material made of PP and PA resin that can be heated by microwave, with excellent back-end processability, i.e., taking into account the processing viscosity and mechanical properties of the material

要点：通过在PP和PA树脂中添加微波吸收剂后，可以提高微波有效加热树脂至熔点的目的，同时能够保证树脂具有较好的加工性能 By adding the microwave absorber to the PP and PA resin, it can improve the effective heating of the resin to its melting point via microwave, and to ensure that the resin has good processability

金发项目A3

新型半芳香族聚酰胺连续聚合工艺 Continuous polymerization process of new semi-aromatic polyamide

要求：半芳香族聚酰胺是由脂肪族二胺与对苯二甲酸和（或）间苯二甲酸缩合聚合而成，其熔点一般都超过300°C。 Semi-aromatic polyamides are derived from the condensation and polymerization of Aliphatic Diamines, Terephthalic Acid and/or Isophthalic Acid with its melting point generally exceeding 300°C.

国外大公司如杜邦、巴斯夫等采用连续熔融聚合工艺生产。其关键技术难点在于：1. 反应温度高。由于半芳香族聚酰胺熔点高，故反应温度一般都在320°C以上；2. 工艺窗口窄。半芳香族聚酰胺熔点高，接近其分解温度，因此聚合温度窗口窄，集中在320-340°C之间。

Continuous melt polymerization process is adopted by big-name companies such as DuPont and BASF. Key technical difficulties are: 1. High reaction temperature. As the melting point of semi-aromatic polyamide is high, the reaction temperature is generally above 320°C; 2. Narrow process window. As the melting point of semi-aromatic polyamide is high and close to its decomposition temperature, the polymerization temperature window is narrow and between 320 - 340°C.

金发项目A4

汽车/家电轻量化高分子材料开发 R&D on lightweight polymer materials for automobile / home appliances

要点：对现有汽车及家电高分子材料内部空心化等技术特征，使高分子材料，如PP、ABS等。

In terms of internal hollowing of polymer materials applied in automobile and home appliances, it should decrease density of polymer materials by 20-25%, maintain its mechanical retention rate above 90%, and be better applied in the injection molding industry.
