美國Hybrid Plastics
美國加州 Hybrid Plastics公司開發(fā)出了一種全新思路的納米增強劑 POSS。其特點是它能溶于溶劑和樹脂中，因而能確保實現分子分散，同時保持低黏度，從而加大了填充量，并且不影響加工流動性。但當溫度降至 POSS的熔點以下時，它便立即固化并形成納米結構起到增強作用。POSS的另一個特點是它的單體或齊聚物都與樹脂發(fā)生接枝共聚，使接枝物玻璃化溫度提高到樹脂本身的分解溫度以上，而接枝產物的分解溫度又比樹脂提高了 40～100 ℃，這使它高溫下仍保持了良好的加工流動性。該公司宣稱，POSS 是近 50 年來開發(fā)出的第 1 種全新思路的化學產品，它具有納米粘土的優(yōu)點，卻沒有納米粘土的缺點。

In the early 1990s, a scientific team under the direction of Dr. Joseph Lichtenhan at Edwards Air Force Base in California invented the first new class of chemical feedstocks to be developed in 50 years - Polyhedral Oligomeric Silsesquioxane or POSS? as it’s known. In 1998, Dr. Lichtenhan and his team spun this POSS? technology out of the Air Force Research Laboratory and founded Hybrid Plastics?. Thus began the process of the Company converting from a small R&D facility to a true manufacturing company. In 2004 the Company took its next major step and relocated from California to Hattiesburg, Mississippi. It acquired a 15 acre manufacturing site and developed an association with one of the best polymers schools in the United States - the University of Southern Mississippi’s School of Polymers and High Performance Materials - which is also located in Hattiesburg.

Today Hybrid Plastics? is one of the top 10 nanotechnology companies in the United States. It’s dedicated staff of scientists and engineers have received awards naming their customer service as unparalleled in the global high performance fillers market. Hybrid Plastics? is unique among nanotech companies because it actually manufactures its nano-products on a multi-ton scale at its 35,000 sq. ft. facility. The Company sells worldwide with 40% of its sales overseas.

Nanotechnology holds the promise of being the science of the 21st Century. Indeed, the National Science and Technology Council has stated "Nanotechnology could impact the production of virtually every human-made object…” POSS? nanoscopic chemicals provide unique opportunities to create revolutionary material combinations through a melding of the desirable properties of ceramics and polymers at the 1 nm length scale. These new combinations enable the circumvention of classic material performance trade-offs by exploiting the synergy and properties that only occur between materials at the nanoscale. They release no VOCs and, thereby, produce no odor or air pollution, while offering easy incorporation into existing manufacturing protocols. These elegant chemicals also push the technology into new applications such as soluble yet biologically inert delivery vehicles for pharmaceuticals and medical applications such as biocompatible prosthetics
