一 | 据New Atlas报道，塑料可以是硬的，也可以是软的，但塑料可以同时具有这两种特性吗？得克萨斯大学奥斯汀分校的科学家们一直在探索这个问题，并生产出一种首创的材料，这种材料在某些部分是柔韧的，而在其他部分是坚硬的，他们认为有一天这种材料会被用于柔性电子产品和机器人。 (ECNS) -- The 34th Guangzhou Expo, underway in Guangzhou, Guangdong Province, put sci-tech innovations and mountain-region specialties on display Saturday, serving as a platform for east-west cooperation that links the Greater Bay Area with Zunyi in Guizhou Province and the Three Gorges Reservoir Area in Chongqing. At the Tianhe venue, a pair of smart glasses drew some of the largest crowds. The device uses eye tracking and vital-sign monitoring to allow contact-free interaction, and it also offers simultaneous interpretation with AI-generated voice cloning in real time. Other exhibits included an AI-assisted system for preliminary diagnosis, designed to ease the strain on medical resources; virus-free seed potato breeding techniques aimed at securing crop yield and quality; and consumer products made from ingredients classified as both food and medicine. All were developed through collaboration among companies, universities, and research institutes, turning laboratory results into everyday applications. Guangzhou's Tianhe District, which has placed sci-tech innovation high on its agenda, is building an innovation hub for the Greater Bay Area. Alongside the technology on show, the expo helped match products with buyers under east-west paired-assistance programs. The Zhuhai-Zunyi session of the Guangzhou Consumption-Assistance Exhibition featured nearly 100 specialty goods from the eight Zunyi counties that receive paired support. One brand zone used displays and on-site tastings to show how a national supply-chain center for new-style tea drinks is taking shape and how Zunyi's tea industry is changing as a result. The center, built jointly by Zhuhai and Zunyi, has doubled the added value of Zunyi tea. Official figures show the city's new-style tea drink industry reached an output value of 1.005 billion yuan (about $139 million) in 2025, up 40% year on year, with local tea farmers among the beneficiaries. Zhuhai Agricultural Control Group has arranged talks with buyers across the Greater Bay Area to widen market access for premium farm produce from Zunyi. In Daozhen Autonomous County, Guizhou Province, Zhuhai-Zunyi cooperation has brought in 107 million yuan in east-west paired-assistance funding, and the output value of local industry has risen sharply since 2021. Companies and cultural tourism operators from Chongqing's Three Gorges Reservoir Area attended the expo as a delegation for the first time, a significant step for the region's signature industries in reaching the national market. Guangzhou has supported the Three Gorges Reservoir Area through paired assistance for years. Exhibits covering both technology and cultural tourism also underlined the region's push for green development. Officials from the Three Gorges Reservoir Area said they would build on the exhibition to deepen ties with Guangzhou and other Greater Bay Area cities, and would take part in trade fairs and promotional events in the bay area on a regular basis.

。在开发这种新型材料时，科学家们从天然材料中获得了灵感，这些材料在某些地方是刚性的，而在其他地方则是柔软和有弹性的。
二 | 皮肤、肌肉、树木和贝类是该团队提供的几个例子，但是创造出混合强度和灵活性的合成版本是很困难的。以前的方法包括将不同的材料混合在一起，但这有其缺点，成品往往在接缝处散开。研究人员声称，在材料科学的这一分支中，一种新型的类似塑料的材料取得了突破。
三 | 作为一个起点，化学家们使用了单体，即聚集在一起形成聚合物的小分子。在这种情况下，聚合物与常用塑料中的聚合物非常相似，但有一两个特殊的技巧。在测试了十几种候选材料后，科学家们发现了一种催化剂，它可以被整合到单体中，使它们对可见光产生反应，用廉价的蓝色LED来传递。这产生了创造一种半结晶聚合物的效果，其属性类似于橡胶，形成一种坚硬的材料。同时，没有暴露在光线下的区域仍然是柔软和有弹性的。“这是同类材料中的第一种，”化学助理教授和论文的通讯作者Zachariah Page说。
四 | “通过应用光来控制结晶，并因此控制材料的物理特性的能力，对于可穿戴电子设备或软体机器人的执行器来说，可能是一种变革。”研究人员称，这种类似塑料的材料的韧性是天然橡胶的10倍，但在不同区域具有不同的物理特性。科学家们想象他们的创造有广泛的应用，包括固定可穿戴技术或医疗设备中的电子元件，以及改善机器人的强度和灵活性。研究第一作者Adrian Rylski说：“我们期待着探索应用这种化学方法来制造包含软硬成分的3D物体。”这项研究发表在《科学》杂志上。
